Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated financial statements include the results of the Company and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated upon consolidation. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the consolidated financial statements filed with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (“Annual Report”) filed with the Securities and Exchange Commission on March 14, 2023. In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive income (loss), stockholders’ equity and cash flows for the interim periods, but are not necessarily indicative of the results of operations or cash flows to be anticipated for the full year 2023 or any future period. The Company has evaluated subsequent events occurring after the date of the condensed consolidated financial statements for events requiring recording or disclosure in the condensed consolidated financial statements. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its significant estimates, including the valuation of accounts receivable, the lives and realization of tangible and intangible assets, contingent consideration liabilities, stock-based compensation expense, customer life, accounting for revenue recognition, contingent liabilities related to legal matters, and income taxes including deferred taxes and any related valuation allowance. In particular, the Company's contingent consideration liabilities are subject to significant estimates surrounding forecasts of certain revenues and other factors. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions it believes to be reasonable under the circumstances. Actual results could differ from those estimates and such differences could be material to the Company’s financial position and results of operations. The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred assets in the future in excess of their net recorded amount, the Company makes an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. Concentrations of Risk Credit Risk – Financial instruments that potentially subject the Company to concentration of credit risk consisted primarily of cash and cash equivalents and accounts receivable from trade customers. The Company maintains its deposits of cash and cash equivalents at two domestic and four international financial institutions. The Company is exposed to credit risk in the event of default by a financial institution to the extent that cash and cash equivalents are in excess of the amount insured by the Federal Deposit Insurance Corporation ("FDIC") and other local country government agencies. The Company generally places its cash and cash equivalents with high-credit quality financial institutions. To date, the Company has not experienced any losses on its cash and cash equivalents. As of March 31, 2023, the Company had $ 3.8 million and $ 25,000 on hand in separate respective accounts with the Company's two domestic financial institutions, for which only $ 250,000 per bank is insured under FDIC limits. Concentration of Accounts Receivable and Contract Asset – At March 31 202 3, three customers accounted for 27 %, 20 % and 16 % of the Company’s total accounts receivable and contract asset, respectively. At March 31, 2022, two customers accounted for 38 % and 15 % of the Company’s total accounts receivable and contract asset. Concentration of Revenues – For the three months ended March 31, 2023, two customer s accounted for 27 % and 10 % of the Company’s total revenues, respectively. For the three months ended March 31, 2022, two customers accounted for 38 % and 10 % of the Company’s total revenues, respectively. Concentration of Suppliers – The Company relies on a limited number of suppliers and contract manufacturers. In particular, a single supplier is currently the sole manufacturer of the Company’s proprietary sensors. Recent Accounting Pronouncements Adopted In June 2016, the Financial Accounting Standards Board ("FASB”) issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this ASU replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit loss and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance was effective at the beginning of the Company’s first quarter of fiscal 2023. The Company adopted this ASU effective January 1, 2023 . The adoption of this ASU did no t have a material impact on the Company's consolidated financial statements.

Business Acquisition	Note 4. Business Acquisition During the first quarter of 2022, the Company completed the acquisition of 100 % of the membership interests in Forensic Logic, LLC (“Forensic Logic”) for purchase consideration of $ 4.9 million in cash, subject to working capital adjustments, and $ 14.3 million in the form of 464,540 shares of the Company's common stock based on the closing price on the date of acquisition. The purchase consideration also included a contingent earnout payable based on Forensic Logic’s revenues generated during 2022 and 2023. The acquisition date fair value of the contingent earnout was $ 12.4 million, resulting in a total purchase consideration of $ 31.6 million. The following table summarizes the assignment of fair value to the identified assets and liabilities recorded as of the acquisition date (in thousands): Cash and cash equivalents $ 303 Accounts receivable and contract asset, net 220 Property and equipment, net 200 Operating lease right-of-use assets 1,893 Software technology 7,140 Tradename 1,000 Customer relationships 8,400 Goodwill 20,155 Other assets 186 Accrued expenses and other current liabilities ( 635 ) Operating lease liabilities ( 1,893 ) Deferred revenue ( 5,382 ) Total estimated consideration $ 31,587 Goodwill primarily represents the value of cash flows from future customers and the employee workforce. The Company expects to deduct the amortization of goodwill and intangible assets for tax purposes. A portion of the amortization deduction will commence upon settlement of contingent consideration liabilities. The Company valued the intangible assets using income-based approaches. Significant assumptions included forecasts of revenues, cost of revenues, research and development expense, sales and marketing expense, general and administrative expense, technology lives, royalty rates, working capital rates, customer attrition rates and other estimates. The Company discounted the cash flows at 24 %, reflecting the risk profile of the assets. Acquisitio n-related expenses totaled $ 0.6 million, of which $ 0.1 million is included in general and administrative expense for the three months ended March 31, 2022.

Fair Value Measurements	Note 5. Fair Value Measurements In November 2020, using a Monte Carlo Simulation approach, and Level III of the fair value hierarchy established by Accounting Standards Codification (“ASC”) 820-10-35-37, the Company estimated the fair value of the contingent consideration liability associated with its acquisition of LEEDS LLC (“LEEDS”) to be $ 0.2 millions as of the acquisition date. During the fourth quarter of 2021, the fair value of the contingent consideration was increased by $ 1.3 million based upon estimated 2022 revenue targets, representing an adjustment to the most likely outcome expected for the liability. During the three months ended March 31, 2023, the Company paid the $ 1.5 million LEEDS contingent consideration balance. In January 2022, using a Monte Carlo Simulation approach and Level III of the fair value hierarchy established by ASC 820-10-35-37, the Company estimated the fair value of the contingent consideration liability associated with its acquisition of Forensic Logic to be $ 12.4 million as of the acquisition date. During the year ended December 31, 2022, and the first quarter of 2023, the fair value of the contingent consideration was decreased by $ 9.2 million based upon revised estimated 2022 and 2023 revenue targets due to delays in certain expected contracts by a small number of significant potential customers. The changes in the fair value of contingent consideration liabilities for the quarters ended March 31 are as follows (in thousands): Three Months Ended March 31, 2023 2022 Beginning balance $ 4,746 $ 1,500 Payment of contingent consideration liability ( 1,500 ) — Change in fair value of contingent consideration ( 6 ) 12,400 Ending balance $ 3,241 $ 13,900 There were no transfers into or out of Level III during the three months ended March 31, 2023 and 2022.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 14. Commitments and Contingencies Contingencies On August 28, 2018, Silvon S. Simmons (the “Plaintiff”) amended a complaint against the City of Rochester, New York and various city employees, filed in the United States District Court, Western District of New York, to add the Company and employees as a defendant. The amended complaint alleges conspiracy to violate the Plaintiff’s civil rights, denial of the right to a fair trial, and malicious prosecution. The Plaintiff claims that the Company colluded with the City of Rochester to fabricate and create gunshot alert evidence to secure Plaintiff’s conviction. On the basis of the allegations, the Plaintiff has petitioned for compensatory and punitive damages and other costs and expenses, including attorney’s fees. The Company believes that the Plaintiff’s claims are without merit and is disputing them vigorously. The Company may become subject to legal proceedings, as well as demands and claims that arise in the normal course of business. Such claims, even if not meritorious, could result in the expenditure of significant financial and management resources. The Company makes a provision for a liability relating to legal matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed and adjusted to include the impacts of negotiations, estimated settlements, legal rulings, advice of legal counsel, and other information and events pertaining to a particular matter. An unfavorable outcome on any litigation matters could require payment of substantial damages, or, in connection with any intellectual property infringement claims, could require the Company to pay ongoing royalty payments or could prevent the Company from selling certain of its products. As a result, a settlement of, or an unfavorable outcome on, any of the matters referenced above or other litigation matters could have a material adverse effect on the Company’s business, operating results, financial condition and cash flows.

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The condensed consolidated financial statements include the results of the Company and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated upon consolidation. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the consolidated financial statements filed with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (“Annual Report”) filed with the Securities and Exchange Commission on March 14, 2023. In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive income (loss), stockholders’ equity and cash flows for the interim periods, but are not necessarily indicative of the results of operations or cash flows to be anticipated for the full year 2023 or any future period. The Company has evaluated subsequent events occurring after the date of the condensed consolidated financial statements for events requiring recording or disclosure in the condensed consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its significant estimates, including the valuation of accounts receivable, the lives and realization of tangible and intangible assets, contingent consideration liabilities, stock-based compensation expense, customer life, accounting for revenue recognition, contingent liabilities related to legal matters, and income taxes including deferred taxes and any related valuation allowance. In particular, the Company's contingent consideration liabilities are subject to significant estimates surrounding forecasts of certain revenues and other factors. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions it believes to be reasonable under the circumstances. Actual results could differ from those estimates and such differences could be material to the Company’s financial position and results of operations. The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. In the event the Company determines that it would be able to realize its deferred assets in the future in excess of their net recorded amount, the Company makes an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.
Concentrations of Risk	Concentrations of Risk Credit Risk – Financial instruments that potentially subject the Company to concentration of credit risk consisted primarily of cash and cash equivalents and accounts receivable from trade customers. The Company maintains its deposits of cash and cash equivalents at two domestic and four international financial institutions. The Company is exposed to credit risk in the event of default by a financial institution to the extent that cash and cash equivalents are in excess of the amount insured by the Federal Deposit Insurance Corporation ("FDIC") and other local country government agencies. The Company generally places its cash and cash equivalents with high-credit quality financial institutions. To date, the Company has not experienced any losses on its cash and cash equivalents. As of March 31, 2023, the Company had $ 3.8 million and $ 25,000 on hand in separate respective accounts with the Company's two domestic financial institutions, for which only $ 250,000 per bank is insured under FDIC limits. Concentration of Accounts Receivable and Contract Asset – At March 31 202 3, three customers accounted for 27 %, 20 % and 16 % of the Company’s total accounts receivable and contract asset, respectively. At March 31, 2022, two customers accounted for 38 % and 15 % of the Company’s total accounts receivable and contract asset. Concentration of Revenues – For the three months ended March 31, 2023, two customer s accounted for 27 % and 10 % of the Company’s total revenues, respectively. For the three months ended March 31, 2022, two customers accounted for 38 % and 10 % of the Company’s total revenues, respectively. Concentration of Suppliers – The Company relies on a limited number of suppliers and contract manufacturers. In particular, a single supplier is currently the sole manufacturer of the Company’s proprietary sensors. Recent Accounting Pronouncements Adopted In June 2016, the Financial Accounting Standards Board ("FASB”) issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this ASU replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit loss and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance was effective at the beginning of the Company’s first quarter of fiscal 2023. The Company adopted this ASU effective January 1, 2023 . The adoption of this ASU did no t have a material impact on the Company's consolidated financial statements.
