	Notes to Condensed Consolidated Financial Statements
	(Unaudited)
	31-Mar-14
	Note A: Basis of Presentation
	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, 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.
	The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q, which requires the Company to make estimates and assumptions that affect amounts reported.  Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission (the “SEC”).  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.  It is the opinion of management that the unaudited condensed consolidated financial statements include all adjustments consisting of normal recurring accruals considered necessary for a fair presentation.  All significant intercompany balances and transactions have been eliminated.
	Operating results for the three-month period ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. The accompanying condensed consolidated financial statements of the Company should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2013 as filed with the SEC.
	Summary of Significant Accounting Policies
	The Company believes that of its significant accounting policies, the following are particularly important to the portrayal of the Company’s results of operations and financial position and may require the application of a higher level of judgment by the Company’s management and, as a result, are subject to an inherent degree of uncertainty.
	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 has 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 North America, the Caribbean and Latin America. 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.
	Inventories
	Inventories are primarily electronic components and finished goods and are valued at the lower of cost or market on the first-in, first-out accounting method.
	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.
	Intangible Assets
	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 March 31, 2014 and December 31, 2013, we determined there was no impairment of intangible assets.  At both March 31, 2014 and December 31, 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. A certain amount of judgment and estimation is required to assess when technological feasibility is established, as well as the ongoing assessment of the recoverability of capitalized costs.  In evaluating the recoverability of capitalized software costs, the Company compares expected product performance, utilizing forecasted revenue amounts, to the total costs incurred to date and estimates of additional costs to be incurred.  If revised forecasted product revenue is less than, and/or revised forecasted costs are greater than, the previously forecasted amounts, the net realizable value may be lower than previously estimated, which could result in the recognition of an impairment charge in the period in which such a determination is made.
	We reached technological feasibility for certain software products and, as a result, have capitalized a total of $867,000 of software development costs through the quarter ended March 31, 2014.  Once the software products are available for release, the capitalized development costs will begin to be amortized to cost of sales over the products’ estimated economic life using the greater of straight-line or a method that results in cost recognition in future periods that is consistent with the anticipated time of product revenue recognition.

Fair Value Measurements And Marketable Securities [Abstract]	'
Fair Value Measurements And Marketable Securities	'
	Note B: 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
	We evaluate impairment at each reporting period for securities where the fair value of the investment is less than its cost. Unrealized gains and losses on our available-for-sale investments are primarily attributable to general changes in interest rates and market conditions. The aggregate unrealized gain or loss on available-for-sale investments was immaterial as of December 31, 2013.
	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.
	Proceeds from maturities or sales of available‑for‑sale securities were $2.6 million and $1.1 million for the three month periods ended March 31, 2014 and 2013, 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 periods ended March 31, 2014 and December 31, 2013 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.
	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.

Stock-Based Compensation [Abstract]	'
Stock-Based Compensation	'
	Note G: 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 six 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 as of the last day of the performance period 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 is 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 three-month periods ended March 31, 2014 and 2013 was $87,000 and $55,000, respectively. At March 31, 2014, a total of 102,394 shares were available for grant under these plans.
	Stock Options
	A summary of the option activity for the first three months of 2014 is as follows:
		Number of Shares	Weighted Average Exercise Price per Share	Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value
	Options outstanding at December 31, 2013	339,750	$         6.73	6.9	$          9,000

	Options exercisable at March 31, 2014	133,688	$         7.67	4.8	$        10,422
	There were no options exercised during the three-month periods ended March 31, 2014 and 2013, respectively.  As of March 31, 2014, there was $639,000 of total unrecognized compensation cost related to non-vested stock options. The weighted average period over which the compensation cost is expected to be recognized is 2.6 years.
	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 March 31, 2014, there were stock awards issued for 3,711 shares with a weighted-average grant date fair value of $5.05.

Loss per Common Share [Abstract]	'
Loss per Common Share	'
	Note H: Loss per Common Share
	Net loss per share is computed by dividing net loss by the daily weighted average number of common shares outstanding during the applicable periods. Diluted net loss per share includes the potentially dilutive effect of common shares subject to outstanding stock options using the treasury stock method. Under the treasury stock method, shares subject to certain outstanding 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 220,555 and 397,000 weighted common shares have been excluded from the diluted weighted shares outstanding for the three-month periods ended March 31, 2014 and 2013, respectively. The potentially dilutive effect of common shares subject to certain outstanding stock options is determined based on net loss. A reconciliation of these amounts is as follows:

Segment Information	'
	Note I: 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 royalties (all of which are received from Econolite), as well as a portion of international sales. 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.
	The following tables set forth selected unaudited financial information for each of our reportable segments (in thousands):

	Note L: Commitments and Contingencies
	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 GAAP, 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 any 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 are conducting an investigation into violations of Polish law related to tenders in the City of Łodź, Poland. In December 2012, the regional prosecutor charged two employees of Image Sensing Systems Europe Limited SP.Z.O.O., our Polish subsidiary (“ISS Poland”), with, among other things, criminal violations of Polish tender and corruption law related to a project in Łodź. Neither the Company nor any of our subsidiaries has been charged with any offense. A Special Subcommittee of our Audit Committee comprised solely of independent directors has retained independent counsel and accounting advisors to conduct 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. This investigation is ongoing, and we have voluntarily disclosed this matter to the Securities and Exchange Commission and the Department of Justice.
	We are cooperating with the Polish prosecutor and intend to cooperate with any other governmental investigation into these matters. We have taken remedial actions, including ending the employment of the two Polish employees, and we are assessing and implementing enhancements to our internal policies, procedures and controls. We cannot predict the outcome of this matter at this time or whether it will have a material adverse impact on our business prospects, financial condition, operating results or cash flows.

	Summary of Significant Accounting Policies
	The Company believes that of its significant accounting policies, the following are particularly important to the portrayal of the Company’s results of operations and financial position and may require the application of a higher level of judgment by the Company’s management and, as a result, are subject to an inherent degree of uncertainty.
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 has 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 North America, the Caribbean and Latin America. 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.
Inventories	'
	Inventories
	Inventories are primarily electronic components and finished goods and are valued at the lower of cost or market on the first-in, first-out accounting method.
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.

	Intangible Assets
	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 March 31, 2014 and December 31, 2013, we determined there was no impairment of intangible assets.  At both March 31, 2014 and December 31, 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. A certain amount of judgment and estimation is required to assess when technological feasibility is established, as well as the ongoing assessment of the recoverability of capitalized costs.  In evaluating the recoverability of capitalized software costs, the Company compares expected product performance, utilizing forecasted revenue amounts, to the total costs incurred to date and estimates of additional costs to be incurred.  If revised forecasted product revenue is less than, and/or revised forecasted costs are greater than, the previously forecasted amounts, the net realizable value may be lower than previously estimated, which could result in the recognition of an impairment charge in the period in which such a determination is made.
	We reached technological feasibility for certain software products and, as a result, have capitalized a total of $867,000
