Organization Consolidation And Presentation Of Financial Statements [Abstract]
Significant Accounting Policies and Recent Accounting Pronouncements	2. Significant Accounting Policies and Recent Accounting Pronouncements Principles of Consolidation — The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Reclassifications — Certain reclassifications have been made to the fiscal year 2019 financial statements to conform to the fiscal year 2020 presentation. The reclassifications had no impact on net loss, total assets, total liabilities, or stockholders’ equity. Use of Estimates — The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The Company believes judgment is involved in determining revenue recognition; the acquisition-date fair value of intangible assets; the fair value of contingent consideration associated with acquisitions; the recoverability of long-lived assets; impairment of goodwill and intangible assets; stock-based compensation expense; and income tax uncertainties. The Company bases these estimates on historical and anticipated results, trends, and various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ materially from those estimates and assumptions. Concentration of Credit Risk — No customer accounted for 10% or more of net revenue for the years ended December 31, 2020 or 2019, respectively. No customer accounted for 10% or more of the Company’s accounts receivable balance as of December 31, 2020 or 2019. The Company does not require collateral or other security to support accounts receivable. To reduce risk, the Company’s management performs ongoing credit evaluations of its customers’ financial condition. The Company maintains allowances for potential credit losses in its consolidated financial statements. Allowance for Doubtful Accounts — The allowance for doubtful accounts is based on the Company’s assessment of the collectibility of customer accounts. The Company regularly reviews its receivables that remain outstanding past their applicable payment terms and establishes an allowance and potential write-offs by considering factors such as historical experience, credit quality, age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. Although the Company expects to collect net amounts due as stated on the consolidated balance sheets, actual collections may differ from these estimated amounts. Inventories — Inventories are stated at the lower of cost (using average cost or standard cost, as applicable) or net realizable value (market). Inventory is written down for excess inventory, technical obsolescence and the inability to sell based primarily on historical sales and expectations for future use. The Company operates in an industry characterized by technological change. The planning of production and inventory levels is based on internal forecasts of customer demand, which are highly unpredictable and can fluctuate substantially. Should the demand for the Company’s products prove to be significantly less than anticipated, the ultimate realizable value of the Company’s inventory could be substantially less than amounts in the consolidated balance sheets. Once inventory has been written down below cost, it is not subsequently written up. Property and Equipment — Property and equipment are stated at cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method over estimated useful lives of three to ten years for furniture, fixture and office equipment, five to seven years for machinery, five years for automobiles and three years for computer software. Leasehold improvements are amortized over the shorter of the lease term or their estimated useful life. Business Combinations — The tangible and identifiable intangible assets acquired and liabilities assumed in a business combination are recorded based on their estimated fair values as of the business combination date, including identifiable intangible assets, which either arise from a contractual or legal right or are separable from goodwill. The Company bases the estimated fair value of identifiable intangible assets acquired in a business combination on independent valuations that use information and assumptions provided by management, which consider management’s estimates of inputs and assumptions that a market participant would use. Any excess purchase price over the estimated fair value assigned to the net tangible and identifiable intangible assets acquired and liabilities assumed is recorded to goodwill. The use of alternative valuation assumptions, including estimated revenue projections, growth rates, cash flows, discount rates, estimated useful lives and probabilities surrounding the achievement of contingent milestones could result in different purchase price allocations and amortization expense in current and future periods. In circumstances where an acquisition involves a contingent consideration arrangement that meets the definition of a liability under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity Transaction costs associated with acquisitions are expensed as incurred in general and administrative expenses. Results of operations and cash flows of acquired companies are included in the Company’s operating results from the date of acquisition. Intangible Assets — Amortizable intangible assets include trademarks, developed technology and customer relationships acquired as part of business combinations. Intangible assets subject to amortization are amortized using the straight-line method over their estimated useful lives ranging from four to twelve years Goodwill — Goodwill represents the excess of the aggregate of the fair value of consideration transferred in a business combination, over the fair value of assets acquired, net of liabilities assumed. In accordance with ASC 350, Intangibles-Goodwill and Other (“ASC 350”), goodwill is not amortized but is tested for impairment on an annual basis, in the fourth quarter, or whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. In testing for goodwill impairment, the Company compares the fair value of its reporting unit to its carrying value including the goodwill of that unit. If the carrying value, including goodwill, exceeds the reporting unit’s fair value, the Company will recognize an impairment loss for the amount by which the carrying amount exceeds the reporting unit’s fair value. The loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit. Long-Lived Assets — The Company reviews long‑lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment loss is recognized when the total estimated future undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. Impairment, if any, is assessed using discounted cash flows or other appropriate measures of fair value. There were no impairment losses recorded during the years ended December 31, 2020 or 2019. Leases — The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and long-term operating lease liabilities on the Company’s consolidated balance sheets. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future payments. The operating lease ROU assets also include any lease payments made and exclude lease incentives and initial direct costs incurred. The Company’s lease terms may include options to extend the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component. Freight Costs — The Company reflects the cost of shipping its products to customers as a cost of revenue. Reimbursements received from customers for freight costs are recognized as product revenue. Research and Development — Costs to research, design, and develop the Company’s products are expensed as incurred and consist primarily of employee compensation, external contractor costs, and fees for the development of prototype products. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. Generally, the Company’s products are released soon after technological feasibility has been established. Costs incurred subsequent to achieving technological feasibility have not been significant and generally have been expensed as incurred. As of December 31, 2020 and 2019, the net amount of capitalized software development costs were $280,000 and $318,000, respectively, and are included in other current and long term assets in the accompanying consolidated balance sheets. No software development costs were capitalized in 2020 or 2019. The Company capitalizes certain costs for its internal-use software incurred during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Internal-use software is amortized on a straight line basis over its estimated useful life, generally three years. The estimated useful life is determined based on management’s judgment on how long the core technology and functionality serves internal needs and the customer base. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The Company recorded amortization expense related to software development costs of $78,000 and $235,000 for the years ended December 31, 2020 and 2019, respectively. Advertising Costs — The Company expenses advertising costs as incurred. Advertising costs were not significant for the years ended December 31, 2020 and 2019. Stock-based Compensation — The Company accounts for all stock-based payment awards, including employee stock options, restricted stock awards, and performance share units in accordance with ASC 718, (“ASC 718”). Under the fair value recognition provisions of ASC 718, stock-based compensation cost is measured at the grant date based on the fair value of the award. Compensation expense for all stock-based payment awards is recognized using the straight-line single-option approach. Employee stock options awards are valued under the single-option approach and amortized on a straight-line basis, net of estimated forfeitures. The value of the portion of the stock option award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Company’s consolidated statements of comprehensive loss. See Note 12, , for further information regarding the Company’s stock-based compensation assumptions and expenses. The Company has elected to use the Black Scholes pricing model to estimate the fair value of its stock options, which incorporates various subjective assumptions including volatility, risk-free interest rate, expected life, and dividend yield to calculate the fair value of stock option awards. Since the Company has been publicly traded for many years, it utilizes its own historical volatility in valuing its stock option grants. The expected life of an award is based on historical experience, the terms and conditions of the stock awards granted to employees, as well as the potential effect from options that have not been exercised at the time. The assumptions used in calculating the fair value of stock-based payment awards represent management’s estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and the Company uses different assumptions, its stock-based compensation expense could be materially different in the future. In addition, the Company estimates the expected forfeiture rate and recognizes expense only for those awards which are ultimately expected-to-vest shares. If the actual forfeiture rate is materially different from the Company’s estimate, the recorded stock-based compensation expense could be different. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Income Taxes — The Company accounts for income taxes in accordance with ASC 740, (“ASC 740”), which requires the asset and liability approach for financial accounting and reporting of income taxes. Deferred income taxes reflect the recognition of future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The carrying value of net deferred tax assets reflects that the Company has been unable to generate sufficient taxable income in certain tax jurisdictions. A valuation allowance is provided to reduce the deferred tax asset to an amount that is more likely than not to be realized. The deferred tax assets are still available for the Company to use in the future to offset taxable income, which would result in the recognition of a tax benefit and a reduction in the Company’s effective tax rate. Actual operating results and the underlying amount and category of income in future years could render the Company’s current assumptions, judgments and estimates of the realizability of deferred tax assets inaccurate, which could have a material impact on its financial position or results of operations. The Company accounts for uncertain tax positions in accordance with ASC 740, which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. It prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. Such changes in recognition or measurement might result in the recognition of a tax benefit or an additional charge to the tax provision in the period. The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated statement of comprehensive loss. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets. See Note 10, Income Taxes Net Loss Per Share — Basic net loss per share is based upon the weighted average number of common shares outstanding during the period. Diluted net loss per share is based upon the weighted average number of common shares and dilutive-potential common share equivalents outstanding during the period, if applicable. Dilutive-potential common share equivalents are excluded from the computation of net loss per share in the loss periods, as their effect would be antidilutive. As the Company has incurred losses from operations during each of the last two fiscal years, shares issuable pursuant to equity awards are excluded from the computation of diluted net loss per share in the accompanying consolidated statements of comprehensive loss, as their effect is anti-dilutive. Comprehensive Loss — Comprehensive loss for the years ended December 31, 2020 and 2019 has been disclosed within the consolidated statements of comprehensive loss. Other accumulated comprehensive loss includes net foreign currency translation adjustments, which are excluded from consolidated net loss. Foreign Currency Translation and Transactions — The functional currencies of the Company’s foreign subsidiaries are the local currencies, except for the Singapore subsidiary, which uses the U.S. dollar as its functional currency. For those subsidiaries whose functional currency is the local currency, the Company translates assets and liabilities to U.S. dollars using period-end exchange rates and translates revenues and expenses using average exchange rates during the period. Exchange gains and losses arising from translation of foreign entity financial statements are included as a component of other comprehensive loss and gains and losses from transactions denominated in currencies other than the functional currency of the Company are included in the Company’s consolidated statements of comprehensive loss. The Company recognized net currency losses of $0.1 million in 2020, and net gains of $0.1 million in 2019. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that the Company adopts as of the specified effective date. Unless otherwise discussed, the Company does not believe that the impact of recently issued standards that are not yet effective will have a material impact on its financial position or results of operations upon adoption. In June 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (326): Measurement of Credit Losses on Financial Instruments Codification Improvement to Topic 326, Financial Instruments – Credit Losses Codification Improvements to Topic 326, Financial Instruments – Credit Losses Derivatives and Hedging , Financial Instruments Financial Instruments Credit Losses (Topic 326) Targeted Transition Relief Financial Instruments-Credit Losses Derivatives and Hedging Leases Codification Improvements to Topic 326, Financial Instruments-Credit Losses. Additionally, ASU No. 2019-10 defers the effective date for the adoption of the new standard on credit losses for public filers that are considered small reporting companies as defined by the SEC to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, which will be fiscal 2023 for the Company if it continues to be classified as a SRC. In February 2020, the FASB issued ASU 2020-02, which provides guidance regarding methodologies, documentation, and internal controls related to expected credit losses. The subsequent amendments will have the same effective date and transition requirements as ASU No. 2016-13. Early adoption is permitted. Topic 326 requires a modified retrospective approach by recording a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. While the Company is currently evaluating the impact of Topic 326, Company does not expect the adoption of the ASU to have a material impact on its consolidated financial statements. In December 2019, FASB issued ASU 2019-12, Income Taxes (740), Simplifying the Accounting for Income Taxes

Revenue From Contract With Customer [Abstract]
Revenue	3. Revenue Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of its products, software licenses, and services, which are generally capable of being distinct and accounted for as separate performance obligations. For contracts with multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation, generally on a relative basis using its standalone selling price. The stated contract value is generally the transaction price to be allocated to the separate performance obligations. Revenue is recognized net of any taxes collected from customers that are subsequently remitted to governmental authorities. Nature of Products and Services The Company derives revenues from sales of hardware products, software licenses, subscriptions, professional services, software maintenance and support, and extended hardware warranties. Hardware Product Revenues — Guarantees Software License Revenues — Subscription Revenues — the right to take possession of the software supporting the subscription service, or if applicable, any hardware devices at any time during the contract period, and as such are not considered separate performance obligations. Revenue is recognized ratably on a straight-line basis over the term of the contract beginning when the service is made available to the customer. Subscription contract terms range from month-to-month to six years in length and billed monthly or annually. Professional Services Revenues — Software Maintenance and Support Revenues — Extended Hardware Warranties Revenues — two Performance Obligation When Performance Obligation is Typically Satisfied When Payment is Typically Due How Standalone Selling Price is Typically Estimated Hardware products When customer obtains control of the product (point-in-time) Within 30-60 days of shipment Observable in transactions without multiple performance obligations Software licenses When license is delivered to customer or made available for download, and the applicable license period has begun (point-in-time) Within 30-60 days of the beginning of license period Established pricing practices for software licenses bundled with software maintenance, which are separately observable in renewal transactions Subscriptions Ratably over the course of the subscription term (over time) In advance of subscription term Contractually stated or list price Professional services As services are performed and/or when contract is fulfilled (point-in-time) Within 30-60 days of delivery Observable in transactions without multiple performance obligations Software maintenance and support services Ratably over the course of the support contract (over time) Within 30-60 days of the beginning of the contract period Observable in renewal transactions Extended hardware warranties Ratably over the course of the support contract (over time) Within 30-60 days of the beginning of the contract period Observable in renewal transactions Significant Judgments The Company’s contracts with customers often include promises to transfer multiple products and services to a customer. For such arrangements, the Company allocates the transaction price to each performance obligation based on its relative standalone selling price (“SSP”). Judgment is required to determine the SSP for each distinct performance obligation in a contract. For the majority of items, the Company estimates SSP using historical transaction data. The Company uses a range of amounts to estimate SSP when it sells each of the products and services separately and needs to determine whether there is a discount to be allocated based on the relative SSP of the various products and services. In instances where SSP is not directly observable, such as when the product or service is not sold separately, the Company determines the SSP using information that may include market conditions and other observable inputs. The determination of SSP is an ongoing process and information is reviewed regularly in order to ensure SSPs reflect current information or trends. Disaggregation of Revenues The Company disaggregates revenue from contracts with customers based on the timing of transfer of goods or services to customers (point-in-time or over time) and geographic region based on the shipping location of the customer. The geographic regions that are tracked are the Americas, Europe and the Middle East, and Asia-Pacific regions. Total net sales based on the disaggregation criteria described above are as follows (in thousands): Year Ended December 31, 2020 2019 Point-in- Point-in- Time Over Time Total Time Over Time Total Americas $ 54,491 $ 3,811 $ 58,302 $ 56,461 $ 4,904 $ 61,365 Europe and the Middle East 9,124 373 9,497 11,078 339 11,417 Asia-Pacific 19,121 — 19,121 10,973 — 10,973 Total $ 82,736 $ 4,184 $ 86,920 $ 78,512 $ 5,243 $ 83,755 Contract Balances Amounts invoiced in advance of services being provided are accounted for as deferred revenue. Nearly all of the Company’s deferred revenue balance is related software maintenance contracts. Payment terms and conditions vary by contract type, although payment is typically due within 30 to 90 days of contract inception. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts do not include a significant financing component. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s products and services, not to receive financing from its customers. Changes in deferred revenue during the years ended December 31, 2020 and 2019 were as follows (in thousands): Year Ended December 31, 2020 2019 Deferred revenue, beginning of period $ 2,833 $ 2,810 Deferral of revenue billed in current period, net of recognition 1,591 2,149 Recognition of revenue deferred in prior periods (2,058 ) (2,126 ) Deferred revenue as, end of period $ 2,366 $ 2,833 Unsatisfied Performance Obligations Revenue expected to be recognized in future periods related to remaining performance obligations, excluding revenue pertaining to contracts that have an original expected duration of one year or less, and contracts where revenue is recognized as invoiced, was approximately $0.9 million as of December 31, 2020. Since the Company typically invoices customers at contract inception, this amount is included in the deferred revenue balance. As of December 31, 2020, the Company expects to recognize approximately 62% of the revenue related to these unsatisfied performance obligations during 2021, 26% during 2022, and 12% thereafter. Assets Recognized from the Costs to Obtain a Contract with a Customer The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company has determined that certain sales incentive programs (i.e. commissions) meet the requirements to be capitalized. Capitalized incremental costs related to contracts are amortized over the respective contract periods. For the years ended December 31, 2020 and 2019, total capitalized costs to obtain contracts were immaterial. Practical Expedients The Company has elected the following practical expedients in accordance with ASC 606, Revenue from Contracts with Customers • The Company expenses costs as incurred for costs to obtain a contract when the amortization period would have been one year or less. These costs include internal sales force compensation programs and certain partner sales incentive programs as the Company has determined annual compensation is commensurate with annual sales activities. • The Company generally expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling and marketing expense. • The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. • The Company does not consider the time value of money for contracts with original durations of one year or less.

Business Combinations [Abstract]
Business Combinations	4. Business Combinations Viscount Systems, Inc. On January 2, 2019, the Company completed the purchase of substantially all the assets of the Freedom, Liberty, and Enterphone™ MESH products and services of Viscount Systems, Inc. (“Viscount”) and the assumption of certain liabilities (the “Asset Purchase”). Under the terms of the purchase agreement, the Company was obligated to pay at closing aggregate consideration of $2.9 million consisting of: (i) payment in cash of approximately $1.3 million, and (ii) the issuance of 419,288 shares of the Company’s common stock with a value of approximately $1.6 million. An aggregate of approximately 31,447 shares of the Company’s common stock issuable at the closing of the transaction were held back for 12 months following the closing for the satisfaction of certain indemnification claims. In the first quarter of 2020, the Company released the 31,447 holdback shares as the indemnification claims were satisfied. Additionally, in the event that revenue from the assets purchased under the agreement in 2019 was greater than certain specified revenue targets, the Company would have been obligated to issue earnout consideration of up to a maximum of $3.5 million payable in shares of the Company’s common stock, subject to certain conditions. In the event that such revenue targets were not met in 2019, but 2020 revenue from the assets purchased exceeded certain higher targets for 2020, then the Company would have been obligated to issue up to a maximum of $2.25 million in earnout consideration in the form of common stock. The maximum total earnout consideration liability for all periods was $3.5 million in the aggregate, payable in the Company’s common stock. As of December 31, 2019, management had assessed the probability of the issuance of shares related to the earnout consideration and determined its fair value to be $750,000. In the first quarter of 2020, the Company and the sellers of the assets acquired from Viscount reached agreement that certain of the 2019 revenue targets were achieved. In the second quarter of 2020, the Company issued to the sellers earnout consideration consisting of 157,233 shares of its common stock with a fair value of approximately $489,000. The Company recognized a reduction in earnout consideration expense of $261,000 in the statements of comprehensive loss during the year ended December 31, 2020, representing the settlement date fair value of the shares issued and the recorded earnout liability. Such earnout targets were not achieved in 2020. Accordingly, n o value was ascribed to the earnout as of December 31, 2020. Assets acquired and liabilities assumed were recorded based on valuations derived from estimated fair value assessments and assumptions used by the Company. The following table summarizes the fair values of assets acquired and liabilities assumed at the date of acquisition (in thousands): Accounts receivable $ 636 Inventory 249 Prepaid expenses and other current assets 29 Property and equipment 190 Operating lease ROU assets 550 Trademarks 160 Customer relationships 710 Developed technology 800 Total identifiable assets acquired 3,324 Accounts payable (372 ) Operating lease liabilities (61 ) Accrued expenses and liabilities (120 ) Deferred revenue (34 ) Earnout consideration liability (200 ) Other current liabilities (326 ) Long-term operating lease liabilities (489 ) Total liabilities assumed (1,602 ) Net identifiable assets acquired 1,722 Goodwill 1,200 Net purchase price $ 2,922 Acquisition related intangibles included in the above table are finite-lived and are being amortized on a straight-line basis over their estimated lives, which approximates the pattern in which the economic benefits of the intangible assets are expected to be realized, as follows (in thousands): Gross Purchased Intangible Assets Estimated Useful Life (in Years) Trademarks $ 160 5 Customer relationships 710 10 Developed technology 800 10 $ 1,670 Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. The acquisition resulted in $1.2 million of goodwill. With the addition of Viscount’s products and services, the Company believes this goodwill largely reflects the expansion of its Premises offerings with advanced, complementary solutions for the commercial and small- and medium-sized business markets, leveraging Freedom’s IT-centric software, defined architecture, and hardware-light platform. In accordance with ASC 350, goodwill is not amortized but is tested for impairment at least annually in the fourth quarter. See Note 6, Goodwill and Intangible Assets

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements The Company determines the fair values of its financial instruments based on a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. Under ASC 820, Fair Value Measurement and Disclosures • Level 1 – Quoted prices (unadjusted) for identical assets and liabilities in active markets; • Level 2 – Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly; and • Level 3 – Unobservable inputs. Assets and Liabilities Measured at Fair Value on a Recurring Basis As of December 31, 2020 and 2019, there were nominal cash equivalents. The Company’s only liabilities measured at fair value on a recurring basis are the contingent consideration associated with the acquisitions of Thursby Software Systems, Inc. and Viscount. The fair value of the earnout consideration is based on achieving certain revenue and profit targets as defined under the respective acquisition agreements. The valuation of the earnout consideration is classified as a Level 3 measurement as it is based on significant unobservable inputs and involves management judgment and assumptions about achieving revenue and profit targets and discount rates. The unobservable inputs used in the measurement of the earnout consideration are highly sensitive to fluctuations and any changes in the inputs or the probability weighting thereof could significantly change the measured value of the earnout consideration at each reporting period. As of December 31, 2019, management had assessed the probability of the issuance of shares related to the Viscount earnout consideration and determined its fair value to be $750,000. In the first quarter of 2020, the Company and the sellers of the assets acquired from Viscount reached agreement that certain of the 2019 revenue targets were achieved. In the second quarter of 2020, the Company issued to the sellers the related earnout consideration consisting of 157,233 shares of its common stock with a fair value of approximately $489,000. Changes in the fair value of liabilities classified in Level 3 of the fair value hierarchy were as follows (in thousands): Viscount Earnout Consideration Balance at December 31, 2019 $ 750 Decrease in fair value of earnout liability (261 ) Issuance of common stock in connection with earnout consideration (489 ) Balance at December 31, 2020 $ — Assets and Liabilities Measured at Fair Value on a Non-recurring Basis Certain of the Company's assets, including goodwill, intangible assets, and privately-held investments, are measured at fair value on a nonrecurring basis if impairment is indicated. Purchased intangible assets are measured at fair value primarily using discounted cash flow projections. For additional discussion of measurement criteria used in evaluating potential impairment involving goodwill and intangible assets, refer to Note 6, Goodwill and Intangible Assets As of December 31, 2020 and 2019, the Company had $348,000 respectively, of privately-held investments measured at fair value on a nonrecurring basis, which were classified as Level 3 assets due to the absence of quoted market prices and inherent lack of liquidity. The Company reviews its investments to identify and evaluate investments that have an indication of possible impairment. The Company adjusts the carrying value for its privately-held investments for any impairment if the fair value is less than the carrying value of the respective assets on an other-than-temporary basis. The amount of privately-held investments is included in other assets in the accompanying consolidated balance sheets. As of December 31, 2020 and 2019, there were no liabilities that are measured and recognized at fair value on a non-recurring basis. Assets and Liabilities Not Measured at Fair Value The carrying amounts of the Company's accounts receivable, prepaid expenses and other current assets, accounts payable, and other accrued liabilities approximate fair value due to their short maturities. The carrying value of the Company’s financial liabilities approximates fair value based upon borrowing rates currently available to the Company for loans with similar terms.

The Company performs an initial assessment of qualitative factors to determine whether the existence of events and circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In performing the qualitative assessment, the Company identifies and considers the significance of relevant key factors, events, and circumstances that affect the fair value of its reporting units. These factors include external factors such as macroeconomic, industry, and market conditions, as well as entity-specific factors, such as actual and planned financial performance. If, after assessing the totality of relevant events and circumstances, the Company determines that it is more likely than not that the fair value of the reporting unit exceeds its carrying value and there is no indication of impairment, no further testing is performed; however, if the Company concludes otherwise, then the Company will perform the quantitative impairment test which compares the estimated fair value of the reporting unit to its carrying value, including goodwill. If the carrying amount of the reporting unit is in excess of its fair value, an impairment loss would be recorded in the consolidated statement of comprehensive loss. During Intangible Assets The following table summarizes the gross carrying amount and accumulated amortization for intangible assets resulting from acquisitions (in thousands): Developed Customer Trademarks Technology Relationships Total Amortization period (in years) 5 10 - 12 4 - 12 Gross carrying amount at December 31, 2020 $ 765 $ 9,123 $ 15,771 $ 25,659 Accumulated amortization (382 ) (5,773 ) (11,941 ) (18,096 ) Intangible assets, net at December 31, 2020 $ 383 $ 3,350 $ 3,830 $ 7,563 Gross carrying amount at December 31, 2019 $ 763 $ 9,109 $ 15,763 $ 25,635 Accumulated amortization (229 ) (4,873 ) (10,429 ) (15,531 ) Intangible assets, net at December 31, 2019 $ 534 $ 4,236 $ 5,334 $ 10,104 Each period, the Company evaluates the estimated remaining useful lives of purchased intangible assets and whether events or changes in circumstances warrant a revision to the remaining period of amortization. If a revision to the remaining period of amortization is warranted, amortization is prospectively adjusted over the remaining useful life of the intangible asset. Intangible assets subject to amortization are amortized on a straight-line basis over their useful lives as outlined in the table above. The Company performs an evaluation of its amortizable intangible assets for impairment at the end of each reporting period. The Company did not identify any impairment indicators during the years ended December 31, 2020 and 2019.

Prior to the Company’s acquisition of Hirsch in 2009, in November 1994, Hirsch had entered into a settlement agreement (the “1994 Settlement Agreement”) with two limited partnerships, Secure Keyboards, Ltd. (“Secure Keyboards”) and Secure Networks, Ltd. (“Secure Networks”). On April 8, 2009, the 1994 Settlement Agreement was amended and restated to replace the royalty-based payment arrangement with an installment payment schedule with contractual payments to be made in future periods through 2021 (the “2009 Settlement Agreement”). On April 30, 2009, as part of the acquisition of Hirsch, the Company provided Secure Keyboards and Secure Networks with a limited guarantee of Hirsch’s payment obligation under the 2009 Settlement Agreement. On April 13, 2020, the Company, Secure Keyboards, and Secure Networks, amended the 2009 Settlement Agreement. The amendment reduced the amount of quarterly payments due under the obligation in 2020, and requires three additional quarterly payments in 2021, increasing the total amount due under the obligation by approximately $90,000. The Company’s remaining payment obligation under the 2009 Settlement Agreement, as amended, was extended through October 31, 2021. The Company included approximately $139,000 of interest expense during the year ended December 31, 2020, and $52,000, net of an $87,000 carrying value adjustment of interest expense during the year ended December 31, 2019, in its consolidated statements of comprehensive loss for interest accreted on the payment obligation.

Following subsequent amendments, on February 8, 2021 the Company amended and restated the Loan and Security Agreement in its entirety (the “Loan and Security Agreement”). The Loan and Security Agreement provides for a $20.0 million revolving loan facility subject to a borrowing base and a $4.0 million non-formula revolving loan facility that is not subject to a borrowing base. The Company’s obligations under the Loan and Security Agreement are collateralized by substantially all of its assets. The maturity date of the main revolving loan facility is February 8, 2023. The non-formula revolving loan facility will terminate on February 7, 2022, however the Company may, at its option if certain conditions are met, convert prior to their maturity any loans under the non-formula revolving loan facility to a term loan that will fully amortize and mature on February 1, 2025. Advances under the revolving loan facilities and the term loan (if converted) will initially bear interest at a per annum rate equal to the prime rate as determined under the Loan and Security Agreement plus 0.25%. The Company may voluntarily prepay amounts outstanding under the revolving loan facilities and the term loan without prepayment charges. In the event the Loan and Security Agreement is terminated prior to February 8, 2023, the Company would be required to pay an early termination fee in the amount of 2.0% of the main revolving loan line if terminated prior to February 8, 2022 and 1% of the main revolving loan line thereafter. Additional borrowing requests under the revolving loan facilities are subject to various customary conditions precedent, including a borrowing base for the main revolving loan facility. The Loan and Security Agreement contains customary representations and warranties and customary affirmative and negative covenants, including, limits or restrictions on the Company’s ability to incur liens, incur indebtedness, make certain restricted payments (including dividends), merge or consolidate and dispose of assets. In addition, the Loan and Security Agreement contains financial covenants requiring that the Company (i) hold $5 million in unrestricted cash in accounts with EWB, (ii) maintain a monthly minimum trailing six-month EBITDA of $0.6 million for the first two quarters of 2021 and $1.2 million thereafter and (iii) maintain, if the Company converts into the term loan and starting with the quarter ending March 31, 2022, a quarterly fixed charge coverage ratio of at least 1.35 : 1.00. The Loan and Security Agreement contains customary events of default that entitle EWB to cause any or all of the Company’s indebtedness under it to become immediately due and payable. The events of default (some of which are subject to applicable grace or cure periods), include, among other things, non-payment defaults, covenant defaults, cross-defaults to other material indebtedness, bankruptcy and insolvency defaults and material judgment defaults. Upon the occurrence and during the continuance of an event of default, EWB may terminate its lending commitment and/or declare all or any part of the unpaid principal of all loans, all interest accrued and unpaid thereon and all other amounts payable under the Loan and Security Agreement to be immediately due and payable. On December 7, 2020, the Company repaid all remaining amounts outstanding under the EWB Term Loan. As of December 31, 2020, the Company was in compliance with all financial covenants under the Revolving Loan Facility. April 21 Funds On May 5, 2020, the Company issued secured subordinated promissory notes in an aggregate principal amount of $4.0 million (the “Notes”) to 21 April Fund, LP and 21 April Fund, Ltd. (collectively referred to as the “April 21 Funds”) pursuant to a Note and Warrant Purchase Agreement entered into with the April 21 Funds (the “Note Purchase Agreement”). The Notes are collateralized by the Company’s assets, but subordinate to the Company’s obligations to EWB under its Loan and Security Agreement. Proceeds from the sale of the Notes were only to be used for expenses incurred by the Company in connection with its provisions of goods and services under a statement of work with a third party. The Notes have an initial term of nine months and do not bear interest during this period. If the Notes are not repaid on or before the nine-month anniversary of issuance, (a) the Notes will thereafter bear interest of 8% per annum, payable quarterly, and (b) additional warrants to purchase common stock would be issuable to the April 21 Funds for each month all or a portion of the Notes remain unpaid, as further detailed in the Note Purchase Agreement. In the event the Notes are not paid in full by the first anniversary of their issuance, May 5, 2021, they shall thereafter bear interest of 12% per annum, payable quarterly, and additional warrants would be issuable to the April 21 Funds. On December 31, 2020, the principal amount outstanding under the Notes was $2.8 million. As discussed in Note 11, Stockholders’ Equity, the fair value of the warrants issued to April 21 Funds was calculated using the Black Scholes pricing model using the following assumptions: estimated volatility of 63.2%, risk free interest rate of 0.24%, no dividend yield, and an expected life of three years. The relative fair value of the warrants of $290,000 was recorded as a direct reduction from the carrying amount of the Notes and is being amortized as interest expense over the term of the April 21 Funds promissory notes. On February 5, 2021, the Company entered into an amendment (the “Amendment”) to its secured subordinated promissory note with April 21 Funds, which extended the initial term of the Notes to March 31, 2021.

A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended December 31, 2020. Such objective evidence limits the ability to consider other subjective evidence such as the Company’s projections for future growth. A valuation allowance of $62.7 million and $62.5 million as of December 31, 2020 and 2019, respectively, has been recorded to offset the related net deferred tax assets as the Company is unable to conclude that it is more likely than not that such deferred tax assets will be realized. The net deferred tax liabilities are primarily from foreign tax liabilities as well as intangibles acquired as a result of the acquisition of Hirsch and 3VR, which are not deductible for tax purposes. Section 951A under the Tax Cuts and Jobs Act (the “Act”) requires a U.S. shareholder of a controlled foreign corporation to include in taxable income the shareholder’s share of global intangible low-taxed income (“GILTI”) for the year. The Company has determined that the Section 951A provisions do apply to its operations and relationships with its controlled foreign corporations (“CFCs”). The Company recorded no GILTI income in 2020 due to net tested losses at its CFCs. The Company recorded GILTI income of $0.5 million in 2019. As of December 31, 2020, the Company had net operating loss carryforwards of $119.4 million for federal, $45.9 million for state and $73.6 million for foreign income tax purposes. Certain of the Company’s federal, state and foreign loss carryforwards have started expiring and will continue to expire through 2040 if not utilized. The Tax Reform Act of 1986 (the “Tax Reform Act”) limits the use of net operating loss and tax credit carryforwards in certain situations where changes occur in stock ownership. The Company completed its acquisition of Bluehill ID AG on January 4, 2010, which resulted in a stock ownership change as defined by the Tax Reform Act. The Company also completed its acquisition of 3VR on February 14, 2018, which resulted in a stock ownership change as defined by the Tax Reform Act. These transactions resulted in limitations on the annual utilization of federal and state net operating loss carryforwards and credits. As a result, the Company reevaluated its available deferred tax assets, and the loss carryforward and credit amounts, excluding the valuation allowance presented above have been adjusted for the limitation resulting from the change in ownership in accordance with the provisions of the Tax Reform Act. The provision for income taxes reconciled to the amount computed by applying the statutory federal tax rate to the loss before income taxes from operations is as follows (in thousands): December 31, 2020 2019 Income tax provision at statutory federal tax rate of 21% $ (1,057 ) $ (173 ) State taxes, net of federal benefit (12 ) 23 Foreign taxes provisions provided for at rates other than U.S statutory rate (202 ) (486 ) Section 951(A) inclusion — 108 Expiration of capital loss carryforwards — (689 ) Change in valuation allowance 1,432 1,668 Permanent differences (76 ) (135 ) Acquisition costs 2 10 Other (14 ) — Total provision for income taxes $ 73 $ 326 The Company applies the provisions of, and accounted for uncertain tax positions in accordance with, ASC 740. ASC 740 clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements. It prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The CARES Act includes provisions relating to refundable payroll tax credits, deferment of the employer portion of certain payroll taxes, net operating loss carryback periods, and alternative minimum tax credit refunds. The Company analyzed the provisions of the CARES Act and determined there was no significant impact to its provision for income taxes for the year ended December 31, 2020. On June 29, 2020, California Governor Gavin Newsom signed Assembly Bill 85 (“AB85”) into law as part of the California 2020 Budget Act, which temporarily suspends the use of California net operating losses and imposes a cap on the amount of business incentive tax credits that companies can utilize against their net income for tax years 2020, 2021, and 2022. The Company analyzed the provisions of AB 85 and determined there was no impact on the Company’s provision for income taxes for the current period. On December 27, 2020, the Consolidated Appropriations Act, 2021 (the “CAA”) was signed ito law. The CAA includes provisions meant to clarify and modify certain items put forth in CARES Act, while providing aid to businesses affected by the pandemic. The CAA allows deductions for expenses paid for by Paycheck Protection Program (“PPP”) and Economic Injury Disaster Loan (“EIDL”) Program, clarifies forgiveness of EIDL advances, and other business provisions. The Company analyzed the provisions of the CAA and determined there was no significant impact to its provision for income taxes for the year ended December 31, 2020. A reconciliation of the beginning and ending amount of unrecognized tax benefits with an impact on the Company’s consolidated balance sheets or results of operations is as follows (in thousands): 2020 2019 Balance at January 1 $ 2,687 $ 2,879 Additions based on tax positions related to the current year 1 2 Additions for tax positions of prior years — 2 Reductions in prior year tax positions (381 ) (196 ) Balance at December 31 $ 2,307 $ 2,687 While timing of the resolution and/or finalization of tax audits is uncertain, the Company does not believe that its unrecognized tax benefits as presented in the above table would materially change in the next 12 months. As of December 31, 2020 and 2019, the Company recognized liabilities for unrecognized tax benefits of $2.3 million and $2.7 million, respectively, which were accounted for as a decrease to deferred tax assets. Since there was a full valuation allowance against these deferred tax assets, there was no impact on the Company’s consolidated balance sheets or statements of comprehensive loss for the years ended December 31, 2020 and 2019. Also the subsequent recognition, if any, of these previously unrecognized tax benefits would not affect the effective tax rate. Such recognition would result in adjustments to other tax accounts, primarily deferred taxes. The amount of unrecognized tax benefits which, if recognized, would affect the tax rate is $0.1 million as of December 31, 2020 and 2019. The Company recognizes interest accrued related to unrecognized tax benefits and penalties as income tax expense. During fiscal 2020, the Company recorded a decrease to accrued penalties of $5,000 and a decrease in accrued interest of $21,000 related to the unrecognized tax benefits noted above. As of December 31, 2020, the Company has recognized a total liability for penalties of $7,000 and interest of $14,000. During fiscal 2019, the Company recorded a decrease in accrued penalties of $1,000 and an increase in accrued interest of $2,000 related to the unrecognized tax benefits noted above. As of December 31, 2019, the Company had recognized a total liability for penalties of $12,000 and interest of $35,000. The Company files U.S. federal, U.S. state and foreign tax returns. The Company generally is no longer subject to tax examinations for years prior to 2016. However, if loss carryforwards of tax years prior to 2016 are utilized in the U.S., these tax years may become subject to investigation by the tax authorities.

Equity [Abstract]
Stockholders' Equity	11. Stockholders’ Equity Preferred Stock The Company is authorized to issue 10,000,000 shares of preferred stock, 40,000 of which have been designated as Series A Participating Preferred Stock, par value $0.001 per share, and 5,000,000 of which have been designated as Series B Non-Voting Convertible Preferred Stock, par value $0.001 per share (the “Series B Preferred Stock”). No shares of the Company’s Series A Participating Preferred Stock were outstanding as of December 31, 2020 and 2019. At both December 31, 2020 and 2019, 5,000,000 shares of the Series B convertible preferred stock The Board may from time to time, without further action by the Company’s stockholders, direct the issuance of shares of preferred stock in other series and may, at the time of issuance, determine the rights, preferences and limitations of each series, including voting rights, dividend rights and redemption and liquidation preferences. Satisfaction of any dividend preferences of outstanding shares of preferred stock would reduce the amount of funds available for the payment of dividends on shares of the Company’s common stock. Holders of shares of preferred stock may be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up of the Company before any payment is made to the holders of shares of the Company’s common stock. Upon the affirmative vote of the Board, without stockholder approval, the Company may issue shares of preferred stock with voting and conversion rights, which could adversely affect the holders of shares of its common stock. Series B Preferred Stock and Private Placement On December 20, 2017, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with each of 21 April Fund, Ltd. and 21 April Fund, LP (collectively, the “Purchasers”), pursuant to which the Company, in a private placement, agreed to issue and sell to the Purchasers an aggregate of up to 5,000,000 shares of the Series B convertible preferred stock Each Share shall be convertible into the Company’s common stock (i) following the sixth (6th) anniversary of the initial closing of the Private Placement or (ii) if earlier, during the thirty (30) day period following the last trading day of any period of three (3) or more consecutive trading days that the closing market price of the Company’s common stock exceeds $10.00. Each Share is convertible at the option of the holder of the Shares into such number of shares of the Company’s common stock determined by taking the accreted value of such Share (purchase price plus accrued but unpaid dividends) and dividing such value by the stated value of such Share ($4.00 per share, subject to adjustment for dilutive issuances, stock splits, stock dividends and the like); provided, however, that the Company shall not convert any Shares if doing so would cause the holder thereof, along with its affiliates, to beneficially own in excess of 19.9% of the outstanding common stock immediately after giving effect to the applicable conversion (the “Ownership Limitation”), unless waiver of this restriction has been effected by the holder requesting conversion of Shares. Based on the current conversion price, the outstanding, including the accretion of dividends shares of Series B convertible preferred stock as of December 31, 2020 would be convertible into 5 Each share of Series B convertible preferred stock a cumulative th Series B convertible preferred stock Series B convertible preferred stock applicable to the Series B convertible preferred stock).

On May 5, 2020, the Company entered into an amendment to the Loan and Security Agreement, which included amending the EWB Warrant, reducing its exercise price from $3.64 to $3.50 per share and extended the expiration date of the EWB Warrant from February 8, 2022 to February 8, 2023. The Company calculated the fair value of the amended EWB Warrant using the Black Scholes pricing model using the following assumptions: estimated volatility of 63.2%, risk free interest rate of 0.24%, no dividend yield, and an expected life of three years. The fair value of the amended EWB Warrant of $42,000, as well as legal and administrative costs of $92,000, were recorded as a direct reduction from the carrying amount of the Revolving Loan Facility and are being amortized as interest expense over the remaining term of the Loan and Security Agreement.

Restructuring And Related Activities [Abstract]
Restructuring and Severance	15. Restructuring and Severance During the year ended December 31, 2019, the Company incurred restructuring and severance related costs of $105,000. These costs were partially offset by the reversal of a restructuring accrual of $91,000 for future rental payment obligations associated with vacated office space at its Fremont, California facility, which was sublet in the third quarter of 2019. In the year ended December 31, 2020, the Company incurred restructuring expenses of $1,716,000, consisting of severance related costs of $375,000, and facility rental related costs associated with office space of an acquired business of approximately $1,341,000. The latter included a charge of $1,199,000 associated with the impairment of the ROU operating lease asset, which was subleased, but subsequently went into default due to non-payment of rent beginning April 1, 2020. Sublease income of $198,000 was received in the first quarter of 2020, however, since the first quarter of 2020, no rental payments were received.

Leases [Abstract]
Leases	16. Leases The Company’s leases consist primarily of operating leases for administrative office space, research and development facilities, a manufacturing facility, and sales offices in various countries around the world. The Company determines if an arrangement is a lease at inception. Some lease agreements contain lease and non-lease components, which are accounted for as a single lease component. Total rent expense was approximately $ 1.5 during the years ended December 31, 2020 and 2019, respectively Initial lease terms are determined at commencement and may include options to extend or terminate the lease when it is reasonably certain the Company will exercise the option. Remaining lease terms range from one to five years, some of which include options to extend for up to five years. Leases with an initial term of twelve months or less are not recorded on the consolidated balance sheets. As the Company’s leases do not provide an implicit rate, the present value of future lease payments is determined using the Company’s incremental borrowing rate based on information available at the lease commencement date.

Legal Proceedings	17. Legal Proceedings On January 1, 2016, certain of the Company’s present and former officers and directors were named as defendants, and the Company was named as nominal defendant, in a shareholder derivative lawsuit filed in the United States District Court for the Northern District of California, entitled Oswald v. Humphreys, et al., Case No. 16-cv-00241-CRB, alleging breach of fiduciary duty and waste claims. On January 25, 2016, certain of the Company’s present and former officers and directors were named as defendants, and the Company was named as nominal defendant, in a shareholder derivative lawsuit filed in the Superior Court of the State of California, County of Alameda, entitled Chopra v. Hart, et al., Case No. RG16801379, alleging breach of fiduciary duty claims. On February 9, 2016, certain of the Company’s present and former officers and directors were named as defendants, and the Company was named as nominal defendant, in a shareholder derivative lawsuit filed in the Superior Court of the State of California, County of Alameda, entitled Wollnik v. Wenzel, et al., Case No. HG16803342, alleging breach of fiduciary duty, corporate waste, gross mismanagement, and unjust enrichment claims. These lawsuits generally allege that the Company made false and/or misleading statements and/or failed to disclose information in certain public filings and disclosures between 2013 and 2015. Each of the lawsuits seeks one or more of the following remedies: unspecified compensatory damages, unspecified exemplary or punitive damages, restitution, declaratory relief, equitable and injunctive relief, and reasonable costs and attorneys’ fees. On May 2, 2016, the court in the Chopra lawsuit entered an order staying proceedings in the Chopra lawsuit in favor of the Oswald lawsuit, based on a stipulation to that effect filed by the parties in the Chopra lawsuit on April 28, 2016. Similarly, on June 28, 2016, the court in the Wollnik lawsuit entered a stipulated order staying proceedings in the Wollnik lawsuit in favor of the Oswald lawsuit. On June 17, 2016, the plaintiff in the Oswald lawsuit filed an amended complaint. On August 1, 2016, the Company filed a motion to dismiss for failure by plaintiff to make a pre-lawsuit demand on the Company’s board of directors, which motion was heard on October 14, 2016. The judge in the Oswald lawsuit issued an order on November 7, 2016 granting the Company’s motion to dismiss, without prejudice. In addition, the court stayed the case so that plaintiff could exercise whatever rights he had under Section 220 of the Delaware General Corporation Law. On or around November 30, 2016, the plaintiff purported to serve a books and records demand under Section 220 of the Delaware General Corporation Law. The Company responded to that demand. On March 21, 2017, the Company and the plaintiff in the Oswald lawsuit filed a stipulation and proposed order lifting the stay of the case, granting the plaintiff leave to amend, and setting a briefing schedule. The plaintiff in the Oswald lawsuit filed his second amended complaint on April 10, 2017. The Company then filed a motion to dismiss that second amended complaint on May 12, 2017. After further briefing and argument, on October 22, 2017, the court issued its written order denying the motion to dismiss on the basis of demand futility. On January 3, 2018, the court entered a stipulated order setting a response and briefing schedule for defendants to the second amended complaint. Defendants filed motions to dismiss the second amended complaint in the Oswald action under Rule 12(b)(6) on January 16, 2018. After further briefing and argument, on April 13, 2018, the court entered an order granting defendants’ motions to dismiss. On April 19, 2018, plaintiff Oswald filed a motion for leave to file a third amended complaint. On that same date, plaintiff Chopra, a plaintiff in a related and stayed derivative action in state court, filed a motion to intervene in the Oswald action. After further briefing and argument, on July 16, 2018, the court entered an order granting the Chopra motion to intervene and denying the Oswald motion for leave to file a third amended complaint. After the filing of an unopposed administrative motion for entry of judgment by defendants, on October 1, 2018, the court entered an order granting administrative motion for entry of final judgment and entered final judgment in favor of all named defendants and against plaintiffs Oswald and Chopra. On October 23, 2018, plaintiff Oswald filed a notice of appeal with the Ninth Circuit. After the appeal was fully-briefed, the matter was argued before the Ninth Circuit on March 5, 2020. On April 2, 2020, the Ninth Circuit issued a memorandum decision affirming final judgment in favor of defendants. In the interim, the state court Chopra and Wollnik actions remained stayed with periodic status conferences. Following the Ninth Circuit’s affirmance of the Oswald judgment in favor of defendants, the parties to the Wollnik action stipulated to its dismissal without prejudice, which was entered by the Court on May 21, 2020. The parties to the Chopra action similarly stipulated to its dismissal without prejudice, which was entered by the Court on June 10, 2020. From time to time, the Company may become subject to claims arising in the ordinary course of business or could be named a defendant in additional lawsuits. The outcome of such claims or other proceedings cannot be predicted with certainty and may have a material effect on the Company’s financial condition, results of operations or cash flows.

Due to the uncertainty in demand from its customers, the Company may have to change, reschedule, or cancel purchases or purchase orders from its suppliers. These changes may lead to vendor cancellation charges on these purchases or contractual commitments. The following table summarizes the Company’s warranty accrual activity during the years ended December 31, 2020 and 2019 (in thousands): Year Ended December 31, 2020 2019 Balance at beginning of period $ 407 $ 316 Warranty accrual acquired in acquisition — 90 Accruals for warranties charged to expense 55 19 Cost of warranty claims (141 ) (18 ) Balance at end of period $ 321 $ 407 The Company provides warranties on certain product sales for periods ranging from 12 to 36 months, and allowances for estimated warranty costs are recorded during the period of sale. The determination of such allowances requires the Company to make estimates of product return rates and expected costs to repair or to replace the products under warranty. The Company currently establishes warranty reserves based on historical warranty costs for each product line combined with liability estimates based on the prior 12 months’ sales activities. If actual return rates and/or repair and replacement costs differ significantly from the Company’s estimates, adjustments to recognize additional cost of sales may be required in future periods. Historically the warranty accrual and the expense amounts have been immaterial.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation — The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Reclassifications	Reclassifications — Certain reclassifications have been made to the fiscal year 2019 financial statements to conform to the fiscal year 2020 presentation. The reclassifications had no impact on net loss, total assets, total liabilities, or stockholders’ equity.
Use of Estimates	Use of Estimates — The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The Company believes judgment is involved in determining revenue recognition; the acquisition-date fair value of intangible assets; the fair value of contingent consideration associated with acquisitions; the recoverability of long-lived assets; impairment of goodwill and intangible assets; stock-based compensation expense; and income tax uncertainties. The Company bases these estimates on historical and anticipated results, trends, and various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ materially from those estimates and assumptions.
Concentration of Credit Risk	Concentration of Credit Risk — No customer accounted for 10% or more of net revenue for the years ended December 31, 2020 or 2019, respectively. No customer accounted for 10% or more of the Company’s accounts receivable balance as of December 31, 2020 or 2019. The Company does not require collateral or other security to support accounts receivable. To reduce risk, the Company’s management performs ongoing credit evaluations of its customers’ financial condition. The Company maintains allowances for potential credit losses in its consolidated financial statements.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts — The allowance for doubtful accounts is based on the Company’s assessment of the collectibility of customer accounts. The Company regularly reviews its receivables that remain outstanding past their applicable payment terms and establishes an allowance and potential write-offs by considering factors such as historical experience, credit quality, age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. Although the Company expects to collect net amounts due as stated on the consolidated balance sheets, actual collections may differ from these estimated amounts.
Inventories	Inventories — Inventories are stated at the lower of cost (using average cost or standard cost, as applicable) or net realizable value (market). Inventory is written down for excess inventory, technical obsolescence and the inability to sell based primarily on historical sales and expectations for future use. The Company operates in an industry characterized by technological change. The planning of production and inventory levels is based on internal forecasts of customer demand, which are highly unpredictable and can fluctuate substantially. Should the demand for the Company’s products prove to be significantly less than anticipated, the ultimate realizable value of the Company’s inventory could be substantially less than amounts in the consolidated balance sheets. Once inventory has been written down below cost, it is not subsequently written up.
Property and Equipment	Property and Equipment — Property and equipment are stated at cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method over estimated useful lives of three to ten years for furniture, fixture and office equipment, five to seven years for machinery, five years for automobiles and three years for computer software. Leasehold improvements are amortized over the shorter of the lease term or their estimated useful life.
Business Combinations	Business Combinations — The tangible and identifiable intangible assets acquired and liabilities assumed in a business combination are recorded based on their estimated fair values as of the business combination date, including identifiable intangible assets, which either arise from a contractual or legal right or are separable from goodwill. The Company bases the estimated fair value of identifiable intangible assets acquired in a business combination on independent valuations that use information and assumptions provided by management, which consider management’s estimates of inputs and assumptions that a market participant would use. Any excess purchase price over the estimated fair value assigned to the net tangible and identifiable intangible assets acquired and liabilities assumed is recorded to goodwill. The use of alternative valuation assumptions, including estimated revenue projections, growth rates, cash flows, discount rates, estimated useful lives and probabilities surrounding the achievement of contingent milestones could result in different purchase price allocations and amortization expense in current and future periods. In circumstances where an acquisition involves a contingent consideration arrangement that meets the definition of a liability under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity Transaction costs associated with acquisitions are expensed as incurred in general and administrative expenses. Results of operations and cash flows of acquired companies are included in the Company’s operating results from the date of acquisition.
Intangible Assets	Intangible Assets — Amortizable intangible assets include trademarks, developed technology and customer relationships acquired as part of business combinations. Intangible assets subject to amortization are amortized using the straight-line method over their estimated useful lives ranging from four to twelve years
Goodwill	Goodwill — Goodwill represents the excess of the aggregate of the fair value of consideration transferred in a business combination, over the fair value of assets acquired, net of liabilities assumed. In accordance with ASC 350, Intangibles-Goodwill and Other (“ASC 350”), goodwill is not amortized but is tested for impairment on an annual basis, in the fourth quarter, or whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. In testing for goodwill impairment, the Company compares the fair value of its reporting unit to its carrying value including the goodwill of that unit. If the carrying value, including goodwill, exceeds the reporting unit’s fair value, the Company will recognize an impairment loss for the amount by which the carrying amount exceeds the reporting unit’s fair value. The loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit.
Long-Lived Assets	Long-Lived Assets — The Company reviews long‑lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment loss is recognized when the total estimated future undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. Impairment, if any, is assessed using discounted cash flows or other appropriate measures of fair value. There were no impairment losses recorded during the years ended December 31, 2020 or 2019.
Leases	Leases — The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and long-term operating lease liabilities on the Company’s consolidated balance sheets. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future payments. The operating lease ROU assets also include any lease payments made and exclude lease incentives and initial direct costs incurred. The Company’s lease terms may include options to extend the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component.
Freight Costs	Freight Costs — The Company reflects the cost of shipping its products to customers as a cost of revenue. Reimbursements received from customers for freight costs are recognized as product revenue.
Research and Development	Research and Development — Costs to research, design, and develop the Company’s products are expensed as incurred and consist primarily of employee compensation, external contractor costs, and fees for the development of prototype products. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. Generally, the Company’s products are released soon after technological feasibility has been established. Costs incurred subsequent to achieving technological feasibility have not been significant and generally have been expensed as incurred. As of December 31, 2020 and 2019, the net amount of capitalized software development costs were $280,000 and $318,000, respectively, and are included in other current and long term assets in the accompanying consolidated balance sheets. No software development costs were capitalized in 2020 or 2019. The Company capitalizes certain costs for its internal-use software incurred during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Internal-use software is amortized on a straight line basis over its estimated useful life, generally three years. The estimated useful life is determined based on management’s judgment on how long the core technology and functionality serves internal needs and the customer base. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The Company recorded amortization expense related to software development costs of $78,000 and $235,000 for the years ended December 31, 2020 and 2019, respectively.
Advertising Costs	Advertising Costs — The Company expenses advertising costs as incurred. Advertising costs were not significant for the years ended December 31, 2020 and 2019.
Stock-based Compensation	Stock-based Compensation — The Company accounts for all stock-based payment awards, including employee stock options, restricted stock awards, and performance share units in accordance with ASC 718, (“ASC 718”). Under the fair value recognition provisions of ASC 718, stock-based compensation cost is measured at the grant date based on the fair value of the award. Compensation expense for all stock-based payment awards is recognized using the straight-line single-option approach. Employee stock options awards are valued under the single-option approach and amortized on a straight-line basis, net of estimated forfeitures. The value of the portion of the stock option award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Company’s consolidated statements of comprehensive loss. See Note 12, , for further information regarding the Company’s stock-based compensation assumptions and expenses. The Company has elected to use the Black Scholes pricing model to estimate the fair value of its stock options, which incorporates various subjective assumptions including volatility, risk-free interest rate, expected life, and dividend yield to calculate the fair value of stock option awards. Since the Company has been publicly traded for many years, it utilizes its own historical volatility in valuing its stock option grants. The expected life of an award is based on historical experience, the terms and conditions of the stock awards granted to employees, as well as the potential effect from options that have not been exercised at the time. The assumptions used in calculating the fair value of stock-based payment awards represent management’s estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and the Company uses different assumptions, its stock-based compensation expense could be materially different in the future. In addition, the Company estimates the expected forfeiture rate and recognizes expense only for those awards which are ultimately expected-to-vest shares. If the actual forfeiture rate is materially different from the Company’s estimate, the recorded stock-based compensation expense could be different. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
Income Taxes	Income Taxes — The Company accounts for income taxes in accordance with ASC 740, (“ASC 740”), which requires the asset and liability approach for financial accounting and reporting of income taxes. Deferred income taxes reflect the recognition of future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The carrying value of net deferred tax assets reflects that the Company has been unable to generate sufficient taxable income in certain tax jurisdictions. A valuation allowance is provided to reduce the deferred tax asset to an amount that is more likely than not to be realized. The deferred tax assets are still available for the Company to use in the future to offset taxable income, which would result in the recognition of a tax benefit and a reduction in the Company’s effective tax rate. Actual operating results and the underlying amount and category of income in future years could render the Company’s current assumptions, judgments and estimates of the realizability of deferred tax assets inaccurate, which could have a material impact on its financial position or results of operations. The Company accounts for uncertain tax positions in accordance with ASC 740, which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. It prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. Such changes in recognition or measurement might result in the recognition of a tax benefit or an additional charge to the tax provision in the period. The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated statement of comprehensive loss. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets. See Note 10, Income Taxes
Net Loss Per Share	Net Loss Per Share — Basic net loss per share is based upon the weighted average number of common shares outstanding during the period. Diluted net loss per share is based upon the weighted average number of common shares and dilutive-potential common share equivalents outstanding during the period, if applicable. Dilutive-potential common share equivalents are excluded from the computation of net loss per share in the loss periods, as their effect would be antidilutive. As the Company has incurred losses from operations during each of the last two fiscal years, shares issuable pursuant to equity awards are excluded from the computation of diluted net loss per share in the accompanying consolidated statements of comprehensive loss, as their effect is anti-dilutive.
Comprehensive Loss	Comprehensive Loss — Comprehensive loss for the years ended December 31, 2020 and 2019 has been disclosed within the consolidated statements of comprehensive loss. Other accumulated comprehensive loss includes net foreign currency translation adjustments, which are excluded from consolidated net loss.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions — The functional currencies of the Company’s foreign subsidiaries are the local currencies, except for the Singapore subsidiary, which uses the U.S. dollar as its functional currency. For those subsidiaries whose functional currency is the local currency, the Company translates assets and liabilities to U.S. dollars using period-end exchange rates and translates revenues and expenses using average exchange rates during the period. Exchange gains and losses arising from translation of foreign entity financial statements are included as a component of other comprehensive loss and gains and losses from transactions denominated in currencies other than the functional currency of the Company are included in the Company’s consolidated statements of comprehensive loss. The Company recognized net currency losses of $0.1 million in 2020, and net gains of $0.1 million in 2019.
Recent Accounting Pronouncements	Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that the Company adopts as of the specified effective date. Unless otherwise discussed, the Company does not believe that the impact of recently issued standards that are not yet effective will have a material impact on its financial position or results of operations upon adoption. In June 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (326): Measurement of Credit Losses on Financial Instruments Codification Improvement to Topic 326, Financial Instruments – Credit Losses Codification Improvements to Topic 326, Financial Instruments – Credit Losses Derivatives and Hedging , Financial Instruments Financial Instruments Credit Losses (Topic 326) Targeted Transition Relief Financial Instruments-Credit Losses Derivatives and Hedging Leases Codification Improvements to Topic 326, Financial Instruments-Credit Losses. Additionally, ASU No. 2019-10 defers the effective date for the adoption of the new standard on credit losses for public filers that are considered small reporting companies as defined by the SEC to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, which will be fiscal 2023 for the Company if it continues to be classified as a SRC. In February 2020, the FASB issued ASU 2020-02, which provides guidance regarding methodologies, documentation, and internal controls related to expected credit losses. The subsequent amendments will have the same effective date and transition requirements as ASU No. 2016-13. Early adoption is permitted. Topic 326 requires a modified retrospective approach by recording a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. While the Company is currently evaluating the impact of Topic 326, Company does not expect the adoption of the ASU to have a material impact on its consolidated financial statements. In December 2019, FASB issued ASU 2019-12, Income Taxes (740), Simplifying the Accounting for Income Taxes
