Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES	1.           DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
	DESCRIPTION OF BUSINESS
	Image Sensing Systems, Inc. (referred to herein as “we,” the “Company,” “us” and “our”) develops and markets software-based computer enabled detection products for use in traffic, safety, security, police and parking applications. We sell our products primarily to distributors and also receive royalties under a license agreement with a manufacturer/distributor for certain of our products. Our products are used primarily by governmental entities.
	PRINCIPLES OF CONSOLIDATION
	The Consolidated Financial Statements include the accounts of Image Sensing Systems, Inc. and its wholly-owned subsidiaries: Image Sensing Systems HK Limited (ISS HK) located in Hong Kong; Image Sensing Systems (Shenzhen) Limited (ISS WOFE) located in China; Image Sensing Systems Holdings Limited (ISS Holdings), Image Sensing Systems Europe Limited (ISS Europe), Image Sensing Systems UK Limited (ISS UK) and Image Sensing Systems England (ISS England) located in the United Kingdom; Image Sensing Systems Europe Limited SP.Z.O.O., (ISS Poland) located in Poland; Image Sensing Systems Spain SLU (ISS Spain) located in Spain; Image Sensing Systems Germany, GmbH (ISS Germany) located in Germany; and ISS Image Sensing Systems Canada Limited (ISS Canada) located in Canada. All significant inter-company transactions and balances have been eliminated in consolidation.
	REVENUE RECOGNITION
	We recognize revenue on a sales arrangement when it is realized or realizable and earned, which occurs when all of the following criteria have been met: persuasive evidence of an arrangement exists; delivery and title transfer have occurred or services have been rendered; the sales price is fixed and determinable; collectability is reasonably assured; and all significant obligations to the customer have been fulfilled.
	Certain sales may contain multiple elements for revenue recognition purposes. We consider each deliverable that provides value to the customer on a standalone basis as a separable element. Separable elements in these arrangements may include the hardware, software, installation services, training and support. We initially allocate consideration to each separable element using the relative selling price method. Selling prices are determined by us based on either vendor-specific objective evidence (“VSOE”) (the actual selling prices of similar products and services sold on a standalone basis) or, in the absence of VSOE, our best estimate of the selling price. Factors considered by us in determining estimated selling prices for applicable elements generally include overall economic conditions, customer demand, costs incurred by us to provide the deliverable, as well as our historical pricing practices. Under these arrangements, revenue associated with each delivered element is recognized in an amount equal to the lesser of the consideration initially allocated to the delivered element or the amount for which payment is not deemed contingent upon future delivery of other elements in the arrangement. Under arrangements where special acceptance protocols exist, installation services and training may not be considered separable. Under those circumstances, revenue for the entire arrangement is recognized upon the completion of installation, training and fulfillment of any other significant obligations specific to the terms of the arrangement. Arrangements that do not contain any separable elements are typically recognized when the products are shipped and title has transferred to the customer.
	Revenue from arrangements for services such as maintenance, repair, consulting and technical support are recognized either as the service is performed or ratably over the defined contractual period for service maintenance contracts.
	Econolite Control Products, Inc. (Econolite) is our licensee that sells certain of our products in the United States, Mexico, Canada and the Caribbean. The royalty of approximately 50% of the gross profit on licensed products is recognized when the products are shipped or delivered by Econolite to its customers.
	We record provisions against sales revenue for estimated returns and allowances in the period when the related revenue is recorded based on historical sales returns and changes in end user demand.
	Revenue is recorded net of taxes collected from customers that are remitted to governmental authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.
	SHIPPING AND HANDLING
	Freight revenue billed to customers is reported within revenue on the Consolidated Statements of Operations, and expenses incurred for shipping products to customers are reported within cost of revenue on the Consolidated Statements of Operations.
	CASH AND CASH EQUIVALENTS
	We consider all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents, both inside and outside the United States, are invested in money market funds and bank deposits in local currency denominations. Cash located in foreign banks was $2.0 million and $1.8 million at December 31, 2014 and 2013, respectively. We hold our cash and cash equivalents with financial institutions and, at times, the amounts of our balances may be in excess of insurance limits.
	MARKETABLE SECURITIES
	We classify marketable debt securities as available-for-sale investments and these securities are stated at their estimated fair value.  The value of these securities is subject to market and credit volatility during the period these investments are held.
	ACCOUNTS RECEIVABLE
	We grant credit to customers in the normal course of business and generally do not require collateral from domestic customers. When deemed appropriate, receivables from customers outside the United States are supported by letters of credit from financial institutions. Management performs on-going credit evaluations of customers. The allowance for doubtful accounts is based on management’s assessment of the collectability of specific customer accounts and includes consideration of the credit worthiness and financial condition of those specific customers. We record an allowance to reduce receivables to the amount that is reasonably believed to be collectible and consider factors such as the financial condition of the customer and the aging of the receivables. If there is a deterioration of a customer’s financial condition, if we become aware of additional information related to the credit worthiness of a customer, or if future actual default rates on trade receivables in general differ from those currently anticipated, we may have to adjust our allowance for doubtful accounts, which would affect earnings in the period the adjustments were made.
	INVENTORIES
	Inventories are primarily electronic components and finished goods and are valued at the lower of cost or market determined under the first-in, first-out accounting method.
	PROPERTY AND EQUIPMENT
	Property and equipment is stated at cost. Additions, replacements, and improvements are capitalized at cost, while maintenance and repairs are charged to operations as incurred. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets and by accelerated methods for income tax purposes. Leasehold improvements are depreciated over the shorter of the estimated useful lives of the assets or the contractual term of the lease, with consideration of lease renewal options if renewal appears probable. Depreciation is recorded over a three- to seven-year period for financial reporting purposes.
	INCOME TAXES
	We record a tax provision for the anticipated tax consequences of the reported results of operations. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those deferred tax assets and liabilities are expected to be realized or settled. We record a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. We believe it is more likely than not that forecasted income, including income that may be generated as a result of certain tax planning strategies, together with the tax effects of the deferred tax liabilities, will be sufficient to fully recover the remaining net realizable value of deferred tax assets. In the event that all or part of the net deferred tax assets are determined not to be realizable in the future, an adjustment to the valuation allowance would be charged to earnings in the period such determination is made. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with management’s expectations could have a material impact on our financial condition and operating results. We recognize penalties and interest expense related to unrecognized tax benefits in income tax expense.
	GOODWILL AND INTANGIBLE ASSETS
	Goodwill represents the excess of acquisition costs over the fair value of the net assets of businesses acquired. Goodwill is not amortized, but instead tested at least annually for impairment. Goodwill is also tested for impairment as changes in circumstances occur indicating that the carrying value may not be recoverable.
	Goodwill impairment testing first requires a comparison of the fair value of each reporting unit to the carrying value. If the carrying value of the reporting unit exceeds fair value, goodwill is considered impaired. Impairment testing for indefinite-lived intangible assets requires a comparison between the fair value and the carrying value of the asset. If the carrying value of the asset exceeds its fair value, the asset is reduced to fair value. See Note 4 to the Consolidated Financial Statements for additional information on goodwill.
	Intangible assets with finite lives are amortized on a straight-line basis over the expected period to be benefited by future cash flows and reviewed for impairment. At both December 31, 2014 and 2013, there were no indefinite-lived intangible assets.
	We capitalize certain software development costs related to software to be sold, leased, or otherwise marketed. Capitalized software development costs include purchased materials and services and other costs associated with the development of new products and services. Software development costs are expensed as incurred until technological feasibility has been established, at which time future costs incurred are capitalized until the product is available for general release to the public. Based on our product development process, technological feasibility is generally established once product and detailed program designs have been completed, uncertainties related to high-risk development issues have been resolved through coding and testing, and we have established that the necessary skills, hardware, and software technology are available for production of the product.
	Capitalized software development costs are subject to an ongoing assessment of recoverability, which is impacted by estimates and assumptions of future revenues and expenses for these software products, as well as other factors such as changes in product technologies. Any portion of unamortized capitalized software development costs that are determined to be in excess of net realizable value have been expensed in the period in which such a determination is made. In performing the ongoing assessment of the recoverability of our software development costs, we determined that the capitalized costs were in excess of net realizable value. As a result, we recorded an impairment of $867,000 during the fourth quarter ended December 31, 2014.
	IMPAIRMENT OF LONG-LIVED ASSETS
	We review the carrying value of long-lived assets or asset groups, such as property and equipment and intangibles subject to amortization, when events or changes in circumstances such as asset utilization, physical change, legal factors, or other matters indicate that the carrying value may not be recoverable. When this review indicates the carrying value of an asset or asset group exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group, we recognize an asset impairment charge against operations. The amount of the impairment loss recorded is the amount by which the carrying value of the impaired asset or asset group exceeds its fair value. No such impairment losses were recorded during the years ended December 31, 2014, 2013 or 2012.
	RESEARCH AND DEVELOPMENT
	Research and development costs associated with new products are charged to operations in the period incurred.
	WARRANTIES
	We generally provide a standard two-year warranty on product sales. We record estimated warranty costs at the time of sale and accrue for specific items at the time that their existence is known and the amounts are determinable. We estimate warranty costs using standard quantitative measures based on historical warranty claim experience and an evaluation of specific customer warranty issues. In addition, warranty provisions are also recognized for certain nonrecurring product claims that are individually significant.
	FOREIGN CURRENCY
	The financial position and results of operations of our foreign subsidiaries are measured using local currency as the functional currency. Assets and liabilities are translated using fiscal period-end exchange rates, and statements of operations are translated using average exchange rates applicable to each period, with the resulting translation adjustments recorded as a separate component of shareholders’ equity under “Accumulated other comprehensive loss”. Gains and losses from foreign currency transactions are recognized in the Consolidated Statements of Operations.
	NET LOSS PER SHARE
	Basic loss per share excludes dilution and is computed by dividing net loss attributable to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted loss per share includes potentially dilutive common shares consisting of stock options, restricted stock and warrants using the treasury stock method.   Under the treasury stock method, shares associated with certain stock options have been excluded from the diluted weighted average shares outstanding calculation because the exercise of those options would lead to a net reduction in common shares outstanding. As a result, stock options to acquire 354,000, 348,000 and 481,000 weighted common shares have been excluded from the diluted weighted shares outstanding calculation for the years ended December 31, 2014, 2013 and 2012, respectively, because the exercise prices were greater than the average market price of the common shares during the period and were excluded from the calculation of diluted net income per share.
	USE OF ESTIMATES
	The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and reported amounts of revenue and expense during the reporting period. Predicting future events is inherently an imprecise activity and, as such, requires the use of judgment. Ultimate results could differ from those estimates. Changes in these estimates will be reflected in the financial statements in future periods.
	STOCK-BASED COMPENSATION
	We measure the cost of employee services received in exchange for the award of equity instruments based on the fair value of the award at the date of grant and recognize the cost over the period during which an employee is required to provide services in exchange for the award. Stock options are granted at exercise prices equal to the closing market price of our stock on the day before the date of grant.
	For purposes of determining estimated fair value of stock-based payment awards, we utilize a Black-Scholes option pricing model, which requires the input of certain assumptions requiring management judgment. Because our employee stock option awards have characteristics significantly different from those of traded options, and because changes in the input assumptions can materially affect fair value estimates, existing models may not provide a reliable single measure of the fair value of employee stock options.  Management will continue to assess the assumptions and methodologies used to calculate estimated fair value of stock-based compensation. Circumstances may change and additional data may become available over time that could result in changes to these assumptions and methodologies and thereby materially impact the fair value determination of future grants of stock-based payment awards. If factors change and we employ different assumptions in future periods, the compensation expense recorded may differ significantly from the stock-based compensation expense recorded in the current period.
	RECENT ACCOUNTING PRONOUNCEMENTS
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 provides new guidance related to how an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, ASU 2014-09 specifies new accounting for costs associated with obtaining or fulfilling contracts with customers and expands the required disclosures related to revenue and cash flows from contracts with customers. This new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early application not permitted. We are currently determining our implementation approach and assessing the impact of ASU 2014-09 on the consolidated financial statements.

FAIR VALUE MEASUREMENTS AND MARKETABLE SECURITIES	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS AND MARKETABLE SECURITIES	2	FAIR VALUE MEASUREMENTS AND MARKETABLE SECURITIES
	The guidance for fair value measurements establishes the authoritative definition of fair value, sets out a framework for measuring fair value and outlines the required disclosures regarding fair value measurements. Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. We use a three-tier fair value hierarchy based upon observable and non-observable inputs as follows:
	●	Level 1 – observable inputs such as quoted prices in active markets;
	●	Level 2 – inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
	●	Level 3 – unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
	Assets and Liabilities that are Measured at Fair Value on a Recurring Basis
	The fair value hierarchy requires the use of observable market data when available. In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability.
	Investments are comprised of high-grade municipal bonds, U.S. government securities and commercial paper and are classified as Level 1 or Level 2, depending on trading frequency and volume and our ability to obtain pricing information on an ongoing basis.
	The amortized cost and market value of our available-for-sale securities by major security type were as follows (in thousands):
			31-Dec-13
			Level 1		Level 2		Level 3		Total
		Bank certificates of deposit	$	—	$	2,639	$	—	$	2,639
			$	—	$	2,639	$	—	$	2,639
	Classification of available-for-sale investments as current or noncurrent is dependent upon our intended holding period, the security’s maturity date, or both.  There were no available-for-sale investments with gross unrealized losses that had been in a continuous unrealized loss position for more than 12 months as of December 31, 2013. The aggregate unrealized gain or loss on available-for-sale investments was immaterial as of December 31, 2013.
	Proceeds from maturities or sales of available-for-sale securities were $2.6 million, $7.7 million and $7.3 million during the years ended December 31, 2014, 2013 and 2012, respectively. Realized gains and losses are determined using the specific identification method.  Realized gains and losses related to sales of available-for-sale investments during the years ended December 31, 2014, 2013 and 2012 were immaterial and included in other income.
	Nonfinancial Assets Measured at Fair Value on a Nonrecurring Basis
	Our intangible assets and other long-lived assets are nonfinancial assets that were acquired either as part of a business combination, individually or with a group of other assets. These nonfinancial assets were initially, and have historically been, measured and recognized at amounts equal to the fair value determined as of the date of acquisition.
	Periodically, these nonfinancial assets are tested for impairment by comparing their respective carrying values to the estimated fair value of the reporting unit or asset group in which they reside. In the quarter ended June 30, 2012, certain of these nonfinancial assets were deemed to be impaired (see Note 4), and we recognized an impairment loss equal to the amount by which the carrying value of each reporting unit exceeded their estimated fair value. Fair value measurements of the reporting units were estimated using certain Level 3 inputs requiring management judgment, including projections of economic conditions and customer demand, revenue and margins, changes in competition, operating costs, working capital requirements, and new product introductions.
	Financial Instruments not Measured at Fair Value
	Certain of our financial instruments are not measured at fair value and are recorded at carrying amounts approximating fair value, based on their short-term nature or variable interest rate. These financial instruments include cash and cash equivalents, accounts receivable, accounts payable and other current assets and liabilities.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	4	GOODWILL AND INTANGIBLE ASSETS
	We apply a fair value based impairment test to the carrying value of goodwill for each reporting unit on an annual basis and on an interim basis if certain events or circumstances indicate that an impairment loss may have occurred. In the second quarter of 2012, we experienced a significant and sustained decline in our stock price.  The decline resulted in our market capitalization falling significantly below the recorded value of our consolidated net assets.  As a result, we concluded a triggering event had occurred and performed an impairment test of goodwill for each reporting unit at that time.
	Based on the results of our initial assessment of impairment of our goodwill (step 1), we determined that the carrying value of each reporting unit exceeded its estimated fair value.  Therefore, we performed the second step of the impairment assessment to determine the implied fair value of goodwill.  In performing the goodwill assessment, we used current market capitalization, discounted cash flows and other factors as the best evidence of fair value.
	As a result of this assessment, we recorded $3.2 million of goodwill impairment charges in the second quarter of 2012.
	Intangible Assets
	Because the intangible assets are accounted for in Great Britain Pounds, they are impacted by period-end rates of exchange to United States Dollars and therefore varied in different reporting periods.
	In performing the ongoing assessment of recoverability on our software development costs, which is impacted by estimates and assumptions of future revenues and expenses for these software products, as well as other factors such as changes in product technologies, we determined that the capitalized costs were in excess of net realizable value. As a result, in the quarter ended December 31, 2014, we recorded an impairment charge of $867,000.
	Intangible assets consisted of the following (dollars in thousands):
			31-Dec-14

	The estimated future amortization expense related to other intangible assets for the next five fiscal years is as follows (dollars in thousands):
			Expense
	2015		$	1,499
	2016			837
	2017			837
	2018			617
	2019			197
	Future amortization amounts presented above are estimates. Actual future amortization expense may be different due to future acquisitions, impairments, changes in amortization periods, or other factors.
	In connection with the triggering events discussed above, we reviewed our long-lived assets and determined that none of the long-lived assets were impaired for our asset groups. The determination was based on reviewing estimated undiscounted cash flows for our asset groups, which were greater than their carrying values. As required under GAAP, this impairment analysis occurred before the goodwill impairment assessment.
	The evaluation of the recoverability of long-lived assets requires us to make significant estimates and assumptions. These estimates and assumptions primarily include, but are not limited to, the identification of the asset group at the lowest level of independent cash flows and the primary asset of the group; and long-range forecasts of revenue, reflecting management’s assessment of general economic and industry conditions, operating income, depreciation and amortization and working capital requirements.

	In May 2014, the Company entered into a credit agreement and related documents with Alliance Bank providing for a revolving line of credit for the Company.  The credit agreement and related documents with Alliance Bank (collectively, the “Alliance Credit Agreement”) provide up to a $5.0 million revolving line of credit.  Amounts due under the Alliance Credit Agreement bear interest at a fixed annual rate of 3.95%. Any advances are secured by the Company’s inventories, accounts receivable, cash, marketable securities, and equipment.  We are subject to certain covenants under the Alliance Credit Agreement.  At December 31, 2014, we had no borrowings under the Alliance Credit Agreement, and we were in compliance with all financial covenants. In March 2015, we entered into an agreement with Alliance Bank amending the Alliance Credit Agreement to extend the maturity date from May 2015 to April 1, 2016.
	Prior to May 12, 2014, we had a revolving line of credit with Associated Bank, National Association (“Associated Bank”) that was initially entered into as of May 1, 2008.  We requested, and Associated Bank granted, a termination to the Credit Agreement effective on May 12, 2014 in connection with the revolving line of credit from Alliance Bank described above.

	As of December 31, 2014, the Company had sustained a significant loss. The net operation loss (“NOL”) carry forward after considering NOL carry back in the United States, United Kingdom, Hong Kong and Canada is $11.5 million, $6.6 million, $1.5 million and $95,000, respectively. The Company’s management believes that it is not more likely than not the net operating losses will be utilized. Accordingly, as of December 31, 2014, a full valuation allowance is provided.
	In accordance with Accounting Standards Codification (“ASC”) 740-30, we have not recognized a deferred tax liability for the undistributed earnings of certain of our foreign operations because those subsidiaries have invested or will invest the undistributed earnings indefinitely. It is impractical for us to determine the amount of unrecognized deferred tax liabilities on these indefinitely reinvested earnings. Deferred taxes are recorded for earnings of foreign operations when we determine that such earnings are no longer indefinitely reinvested.
	We realize an income tax benefit from the exercise or early disposition of certain stock options.  This benefit results in a decrease in current income taxes payable and an increase in additional paid-in capital.
	A reconciliation of the beginning and ending amount of the tax liability for uncertain tax positions is as follows (in thousands):
		Balance at December 31, 2012		$	18

	Balance at December 31, 2014		$	—
Included in the balance of uncertain tax positions at December 31, 2014 are immaterial potential benefits that, if recognized, would affect the effective tax rate.  The amount of unrecognized tax benefits are not expected to change materially within the next 12 months. At December 31, 2013 and 2012, we had no accrued interest related to uncertain income tax positions. At December 31, 2013 and 2012, no accrual for penalties related to uncertain tax positions existed. Interest and penalties related to uncertain tax positions are included in interest expense and general and administrative expense, respectively, on our Consolidated Statements of Operations.
We are subject to income taxes in the U.S. federal jurisdiction and various state and foreign jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and require significant judgment to apply. Generally, we are subject to U.S. federal, state, local and foreign tax examinations by taxing authorities for years after the fiscal year ended December 31, 2010.
At December 31, 2014 and 2013, domestic and certain of our foreign subsidiaries were expected to receive income tax refunds within the next fiscal year. This current income tax receivable is included in Prepaid Expenses and Other Current Assets on our Consolidated Balance Sheets.

	Stock-Based Compensation
	We compensate officers, directors and key employees with stock-based compensation under stock plans approved by our shareholders and administered under the supervision of our Board of Directors. Stock option awards are granted at exercise prices equal to the closing price of our stock on the day before the date of grant. Generally, options vest proportionally over periods of three to five years from the dates of the grant, beginning one year from the date of grant, and have a contractual term of nine to ten years.
	Performance stock options are time based; however, the final number of awards earned and the related compensation expense is adjusted up or down to the extent the performance target is met. The actual number of shares that will ultimately vest ranges from 90% to 100% of the targeted amount if the minimum performance target is achieved.  For performance stock awards granted in 2014, the performance target was revenue. We evaluate the likelihood of meeting the performance target at each reporting period and adjust compensation expense, on a cumulative basis, based on the expected achievement of each performance target.
	Compensation expense, net of estimated forfeitures, is recognized ratably over the vesting period. Stock-based compensation expense included in general and administrative expense for the years ended December 31, 2014, 2013 and 2012 was $271,000, $213,000 and $244,000, respectively. At December 31, 2014, a total of 556,989 shares were available for grant under these plans.
	The following table summarizes stock option activity for 2014, 2013 and 2012:

	*Weighted Average Exercise Price
	Options outstanding at December 31, 2014 had a weighted average remaining contractual term of 7.0 years and had no aggregate intrinsic value. Options eligible for exercise at December 31, 2014 had a weighted average remaining contractual term of 5.4 years and had no aggregate intrinsic value.
	There were no stock options exercised during the fiscal year ended December 31, 2014. The total intrinsic value of stock options exercised during the fiscal years ended December 31, 2013 and 2012 was $4,000 and $208,000, respectively.
	The fair value of stock options granted under stock-based compensation programs has been estimated as of the date of each grant using the multiple option form of the Black-Scholes valuation model, based on the grant price and assumptions regarding the expected grant life, stock price volatility, dividends, and risk-free interest rates. Each vesting period of an option award is valued separately, with this value being recognized evenly over the vesting period. The weighted average per share grant date fair value of options to purchase 167,500, 86,000 and 159,750 shares granted for the years ended December 31, 2014, 2013 and 2012 was $2.20, $3.53 and $1.82, respectively. The weighted average assumptions used to determine the fair value of stock options granted during those fiscal years were as follows:
			2014			2013			2012
	Expected life (in years)		5			5			4.8
	Risk-free interest rate		1.55	%		1.52	%		0.72	%
	Expected volatility		50	%		60	%		42	%
	Dividend yield		0	%		0	%		0	%
	The expected life represents the period that the stock option awards are expected to be outstanding and was determined based on historical and anticipated future exercise and expiration patterns. The risk-free interest rate used is based on the yield of constant maturity U.S. Treasury bonds on the grant date with a remaining term equal to the expected life of the grant. We estimate stock price volatility based on a historical weekly price observation. The dividend yield assumption is based on the annualized current dividend divided by the share price on the grant date.  We have not historically paid any cash dividends and do not expect to do so in the foreseeable future.
	Other information pertaining to options for the years ended December 31, 2014, 2013 and 2012 is as follows:
			2014				2013				2012
	Stock-based compensation expense recognized within general and administrative expense on the consolidated statements of operations		$	271,000			$	213,000			$	244,000
	Cash received from the exercise of options			—				8,500				121,000
	Excess income tax benefits from exercise of stock options			—				—				71,000
	Stock Awards
	We issue stock awards as a portion of the annual retainer for each director on a quarterly basis.  The stock awards are fully vested at the time of issuance. Compensation expense related to stock awards is determined on the grant date based on the publicly quoted fair market value of our common stock and is charged to earnings on the grant date.  During the quarter ended December 31, 2014, there were stock awards issued for 8,168 shares with a weighted-average grant date fair value of $3.065.  For the year ended December 31, 2014, there were stock awards issued for 21,116 shares with a weighted-average grant date fair value of $4.29.

Segment Reporting [Abstract]
SEGMENT INFORMATION	13.           SEGMENT INFORMATION
	The Company’s Chief Executive Officer and management regularly review financial information for the Company’s three discrete operating segments. Based on similarities in the economic characteristics, nature of products and services, production processes, type or class of customer served, method of distribution and regulatory environments, the operating segments have been aggregated for financial statement purposes and categorized into three reportable segments:  Intersection, Highway and License Plate Recognition (“LPR”). Autoscope® video is our machine-vision product line, and revenue consists of royalties (all of which are received from Econolite), as well as a portion of international product sales. Video products are normally sold in the Intersection segment. The Autoscope® radar is our radar product line, and revenue consists of international and North American product sales as well as a portion of royalties (all of which are received from Econolite). Radar products are normally sold in the Highway segment. Autoscope® license plate recognition is our LPR product line.  All segment revenues are derived from external customers.
	Operating expenses and total assets are not allocated to the segments for internal reporting purposes. Due to the changes in how we manage our business, we may reevaluate our segment definitions in the future.

	Litigation
	We are involved from time to time in various legal proceedings arising in the ordinary course of our business, including primarily commercial, product liability, employment and intellectual property claims. In accordance with generally accepted accounting principles in the United States, we record a liability in our Consolidated Financial Statements with respect to any of these matters when it is both probable that a liability has been incurred and the amount of the liability can be reasonably estimated. With respect to currently pending legal proceedings, we have not established an estimated range of reasonably possible additional losses either because we believe that we have valid defenses to claims asserted against us or the proceeding has not advanced to a stage of discovery that would enable us to establish an estimate. We currently do not expect the outcome of these matters to have a material effect on our consolidated results of operations, financial position or cash flows. Litigation, however, is inherently unpredictable, and it is possible that the ultimate outcome of one or more claims asserted against us could adversely impact our results of operations, financial position or cash flows. We expense legal costs as incurred.
	Investigation Matter
	As previously disclosed, Polish authorities conducted an investigation into violations of Polish law related to tenders in the City of Łodź, Poland. A Special Subcommittee of our Audit Committee comprised solely of independent directors retained independent counsel and accounting advisors who conducted an investigation focusing on possible violations of Company policy, internal controls, and laws, including the Foreign Corrupt Practices Act, the U.K. Anti-Bribery Act and Polish law. We voluntarily disclosed this matter to the United States Securities and Exchange Commission (“SEC”) and the Department of Justice (“DOJ”).
	During the third quarter of 2014, we received a letter from the DOJ informing us that their inquiry into this matter has been closed, citing the Company’s voluntary disclosure, thorough investigation, cooperation and voluntary enhancements to its compliance program. Additionally, the SEC previously notified the Company that it had closed its investigation without recommending enforcement action.
	Neither the Company nor any of our subsidiaries was charged with any offense, and there were no fines levied at the close of the investigation by the DOJ or SEC.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS	DESCRIPTION OF BUSINESS
	Image Sensing Systems, Inc. (referred to herein as “we,” the “Company,” “us” and “our”) develops and markets software-based computer enabled detection products for use in traffic, safety, security, police and parking applications. We sell our products primarily to distributors and also receive royalties under a license agreement with a manufacturer/distributor for certain of our products. Our products are used primarily by governmental entities.
PRINCIPLES OF CONSOLIDATION	PRINCIPLES OF CONSOLIDATION
	The Consolidated Financial Statements include the accounts of Image Sensing Systems, Inc. and its wholly-owned subsidiaries: Image Sensing Systems HK Limited (ISS HK) located in Hong Kong; Image Sensing Systems (Shenzhen) Limited (ISS WOFE) located in China; Image Sensing Systems Holdings Limited (ISS Holdings), Image Sensing Systems Europe Limited (ISS Europe), Image Sensing Systems UK Limited (ISS UK) and Image Sensing Systems England (ISS England) located in the United Kingdom; Image Sensing Systems Europe Limited SP.Z.O.O., (ISS Poland) located in Poland; Image Sensing Systems Spain SLU (ISS Spain) located in Spain; Image Sensing Systems Germany, GmbH (ISS Germany) located in Germany; and ISS Image Sensing Systems Canada Limited (ISS Canada) located in Canada. All significant inter-company transactions and balances have been eliminated in consolidation.
REVENUE RECOGNITION	REVENUE RECOGNITION
	We recognize revenue on a sales arrangement when it is realized or realizable and earned, which occurs when all of the following criteria have been met: persuasive evidence of an arrangement exists; delivery and title transfer have occurred or services have been rendered; the sales price is fixed and determinable; collectability is reasonably assured; and all significant obligations to the customer have been fulfilled.
	Certain sales may contain multiple elements for revenue recognition purposes. We consider each deliverable that provides value to the customer on a standalone basis as a separable element. Separable elements in these arrangements may include the hardware, software, installation services, training and support. We initially allocate consideration to each separable element using the relative selling price method. Selling prices are determined by us based on either vendor-specific objective evidence (“VSOE”) (the actual selling prices of similar products and services sold on a standalone basis) or, in the absence of VSOE, our best estimate of the selling price. Factors considered by us in determining estimated selling prices for applicable elements generally include overall economic conditions, customer demand, costs incurred by us to provide the deliverable, as well as our historical pricing practices. Under these arrangements, revenue associated with each delivered element is recognized in an amount equal to the lesser of the consideration initially allocated to the delivered element or the amount for which payment is not deemed contingent upon future delivery of other elements in the arrangement. Under arrangements where special acceptance protocols exist, installation services and training may not be considered separable. Under those circumstances, revenue for the entire arrangement is recognized upon the completion of installation, training and fulfillment of any other significant obligations specific to the terms of the arrangement. Arrangements that do not contain any separable elements are typically recognized when the products are shipped and title has transferred to the customer.
	Revenue from arrangements for services such as maintenance, repair, consulting and technical support are recognized either as the service is performed or ratably over the defined contractual period for service maintenance contracts.
	Econolite Control Products, Inc. (Econolite) is our licensee that sells certain of our products in the United States, Mexico, Canada and the Caribbean. The royalty of approximately 50% of the gross profit on licensed products is recognized when the products are shipped or delivered by Econolite to its customers.
	We record provisions against sales revenue for estimated returns and allowances in the period when the related revenue is recorded based on historical sales returns and changes in end user demand.
	Revenue is recorded net of taxes collected from customers that are remitted to governmental authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.
SHIPPING AND HANDLING	SHIPPING AND HANDLING
	Freight revenue billed to customers is reported within revenue on the Consolidated Statements of Operations, and expenses incurred for shipping products to customers are reported within cost of revenue on the Consolidated Statements of Operations.
CASH AND CASH EQUIVALENTS	CASH AND CASH EQUIVALENTS
	We consider all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents, both inside and outside the United States, are invested in money market funds and bank deposits in local currency denominations. Cash located in foreign banks was $2.0 million and $1.8 million at December 31, 2014 and 2013, respectively. We hold our cash and cash equivalents with financial institutions and, at times, the amounts of our balances may be in excess of insurance limits.
MARKETABLE SECURITIES	MARKETABLE SECURITIES
	We classify marketable debt securities as available-for-sale investments and these securities are stated at their estimated fair value.  The value of these securities is subject to market and credit volatility during the period these investments are held.
ACCOUNTS RECEIVABLE	ACCOUNTS RECEIVABLE
	We grant credit to customers in the normal course of business and generally do not require collateral from domestic customers. When deemed appropriate, receivables from customers outside the United States are supported by letters of credit from financial institutions. Management performs on-going credit evaluations of customers. The allowance for doubtful accounts is based on management’s assessment of the collectability of specific customer accounts and includes consideration of the credit worthiness and financial condition of those specific customers. We record an allowance to reduce receivables to the amount that is reasonably believed to be collectible and consider factors such as the financial condition of the customer and the aging of the receivables. If there is a deterioration of a customer’s financial condition, if we become aware of additional information related to the credit worthiness of a customer, or if future actual default rates on trade receivables in general differ from those currently anticipated, we may have to adjust our allowance for doubtful accounts, which would affect earnings in the period the adjustments were made.
INVENTORIES	INVENTORIES
	Inventories are primarily electronic components and finished goods and are valued at the lower of cost or market determined under the first-in, first-out accounting method.
PROPERTY AND EQUIPMENT	PROPERTY AND EQUIPMENT
	Property and equipment is stated at cost. Additions, replacements, and improvements are capitalized at cost, while maintenance and repairs are charged to operations as incurred. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets and by accelerated methods for income tax purposes. Leasehold improvements are depreciated over the shorter of the estimated useful lives of the assets or the contractual term of the lease, with consideration of lease renewal options if renewal appears probable. Depreciation is recorded over a three- to seven-year period for financial reporting purposes.
INCOME TAXES	INCOME TAXES
	We record a tax provision for the anticipated tax consequences of the reported results of operations. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those deferred tax assets and liabilities are expected to be realized or settled. We record a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. We believe it is more likely than not that forecasted income, including income that may be generated as a result of certain tax planning strategies, together with the tax effects of the deferred tax liabilities, will be sufficient to fully recover the remaining net realizable value of deferred tax assets. In the event that all or part of the net deferred tax assets are determined not to be realizable in the future, an adjustment to the valuation allowance would be charged to earnings in the period such determination is made. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with management’s expectations could have a material impact on our financial condition and operating results. We recognize penalties and interest expense related to unrecognized tax benefits in income tax expense.
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND INTANGIBLE ASSETS
	Goodwill represents the excess of acquisition costs over the fair value of the net assets of businesses acquired. Goodwill is not amortized, but instead tested at least annually for impairment. Goodwill is also tested for impairment as changes in circumstances occur indicating that the carrying value may not be recoverable.
	Goodwill impairment testing first requires a comparison of the fair value of each reporting unit to the carrying value. If the carrying value of the reporting unit exceeds fair value, goodwill is considered impaired. Impairment testing for indefinite-lived intangible assets requires a comparison between the fair value and the carrying value of the asset. If the carrying value of the asset exceeds its fair value, the asset is reduced to fair value. See Note 4 to the Consolidated Financial Statements for additional information on goodwill.
	Intangible assets with finite lives are amortized on a straight-line basis over the expected period to be benefited by future cash flows and reviewed for impairment. At both December 31, 2014 and 2013, there were no indefinite-lived intangible assets.
	We capitalize certain software development costs related to software to be sold, leased, or otherwise marketed. Capitalized software development costs include purchased materials and services and other costs associated with the development of new products and services. Software development costs are expensed as incurred until technological feasibility has been established, at which time future costs incurred are capitalized until the product is available for general release to the public. Based on our product development process, technological feasibility is generally established once product and detailed program designs have been completed, uncertainties related to high-risk development issues have been resolved through coding and testing, and we have established that the necessary skills, hardware, and software technology are available for production of the product.
	Capitalized software development costs are subject to an ongoing assessment of recoverability, which is impacted by estimates and assumptions of future revenues and expenses for these software products, as well as other factors such as changes in product technologies. Any portion of unamortized capitalized software development costs that are determined to be in excess of net realizable value have been expensed in the period in which such a determination is made. In performing the ongoing assessment of the recoverability of our software development costs, we determined that the capitalized costs were in excess of net realizable value. As a result, we recorded an impairment of $867,000 during the fourth quarter ended December 31, 2014.
IMPAIRMENT OF LONG-LIVED ASSETS	IMPAIRMENT OF LONG-LIVED ASSETS
	We review the carrying value of long-lived assets or asset groups, such as property and equipment and intangibles subject to amortization, when events or changes in circumstances such as asset utilization, physical change, legal factors, or other matters indicate that the carrying value may not be recoverable. When this review indicates the carrying value of an asset or asset group exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group, we recognize an asset impairment charge against operations. The amount of the impairment loss recorded is the amount by which the carrying value of the impaired asset or asset group exceeds its fair value. No such impairment losses were recorded during the years ended December 31, 2014, 2013 or 2012.
RESEARCH AND DEVELOPMENT	RESEARCH AND DEVELOPMENT
	Research and development costs associated with new products are charged to operations in the period incurred.
WARRANTIES	WARRANTIES
	We generally provide a standard two-year warranty on product sales. We record estimated warranty costs at the time of sale and accrue for specific items at the time that their existence is known and the amounts are determinable. We estimate warranty costs using standard quantitative measures based on historical warranty claim experience and an evaluation of specific customer warranty issues. In addition, warranty provisions are also recognized for certain nonrecurring product claims that are individually significant.
FOREIGN CURRENCY	FOREIGN CURRENCY
	The financial position and results of operations of our foreign subsidiaries are measured using local currency as the functional currency. Assets and liabilities are translated using fiscal period-end exchange rates, and statements of operations are translated using average exchange rates applicable to each period, with the resulting translation adjustments recorded as a separate component of shareholders’ equity under “Accumulated other comprehensive loss”. Gains and losses from foreign currency transactions are recognized in the Consolidated Statements of Operations.
NET LOSS PER SHARE	NET LOSS PER SHARE
	Basic loss per share excludes dilution and is computed by dividing net loss attributable to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted loss per share includes potentially dilutive common shares consisting of stock options, restricted stock and warrants using the treasury stock method.   Under the treasury stock method, shares associated with certain stock options have been excluded from the diluted weighted average shares outstanding calculation because the exercise of those options would lead to a net reduction in common shares outstanding. As a result, stock options to acquire 354,000, 348,000 and 481,000 weighted common shares have been excluded from the diluted weighted shares outstanding calculation for the years ended December 31, 2014, 2013 and 2012, respectively, because the exercise prices were greater than the average market price of the common shares during the period and were excluded from the calculation of diluted net income per share.
USE OF ESTIMATES	USE OF ESTIMATES
	The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and reported amounts of revenue and expense during the reporting period. Predicting future events is inherently an imprecise activity and, as such, requires the use of judgment. Ultimate results could differ from those estimates. Changes in these estimates will be reflected in the financial statements in future periods.
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION
	We measure the cost of employee services received in exchange for the award of equity instruments based on the fair value of the award at the date of grant and recognize the cost over the period during which an employee is required to provide services in exchange for the award. Stock options are granted at exercise prices equal to the closing market price of our stock on the day before the date of grant.
	For purposes of determining estimated fair value of stock-based payment awards, we utilize a Black-Scholes option pricing model, which requires the input of certain assumptions requiring management judgment. Because our employee stock option awards have characteristics significantly different from those of traded options, and because changes in the input assumptions can materially affect fair value estimates, existing models may not provide a reliable single measure of the fair value of employee stock options.  Management will continue to assess the assumptions and methodologies used to calculate estimated fair value of stock-based compensation. Circumstances may change and additional data may become available over time that could result in changes to these assumptions and methodologies and thereby materially impact the fair value determination of future grants of stock-based payment awards. If factors change and we employ different assumptions in future periods, the compensation expense recorded may differ significantly from the stock-based compensation expense recorded in the current period.
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 provides new guidance related to how an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, ASU 2014-09 specifies new accounting for costs associated with obtaining or fulfilling contracts with customers and expands the required disclosures related to revenue and cash flows from contracts with customers. This new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early application not permitted. We are currently determining our implementation approach and assessing the impact of ASU 2014-09 on the consolidated financial statements.
