Image Sensing Systems Announces Fourth Consecutive Year of Record Financial Results

Saint Paul, Minn., February 20, 2006 – Image Sensing Systems, Inc. (ISS) (NASDAQ Small Cap: ISNS) announced today that its net income for 2005 was a $2,841,000 or $.79 per share ($.73 per diluted share) versus net income of $2,694,000 or $.79 per share ($.71 per diluted share) for 2004. Net income for the fourth quarter was $689,000 or $.19 per share ($.18 per diluted share), versus net income of $418,000 or $.12 per share ($.11 per diluted share) for the comparable period in 2004. The fourth quarter of 2005 marks the fifteenth consecutive quarter of profitability for the company.

Revenues for fiscal year 2005 were $11,002,000, compared to $10,830,000 in fiscal year 2004. Royalty income from sales in North America was $8,595,000, compared to $7,521,000 in 2004, while international sales were $2,407,000, compared to $3,309,000 in 2004. Sales of Autoscope products by the Company’s North American distributor continued to show double-digit sales growth in the fourth quarter and ended the year with 14% growth over 2004. International sales for the fourth quarter were $761,000, an increase of 77% from $429,000 in the comparable quarter of 2004, but decreased to $2,407,000 in 2005 from $3,309,000 in 2004. Sales by the Company’s European subsidiary for both the fourth quarter and fiscal year showed a significant increase over 2004, while its Asian subsidiary continued to have difficulty selling product which impacted both consolidated revenues and profitability. While disappointed with sales results of the Asian subsidiary, the Company’s continued sales growth in North America and Europe, has positioned its Autoscope products as the leader in those markets. The Company has taken remedial steps, and continues to do so, to turn around the Asian market position.

Jim Murdakes, Chairman and CEO commented, “We were very pleased with our continued positive financial results for the year and quarter as we registered our 15th consecutive quarter of profitability. Econolite Control Products, Inc., our North American distributor, had an outstanding year selling our Autoscope products and continued to increase market share in this market. Our European subsidiary also had an exceptional year selling Autoscope products while maintaining profitability even while expanding our territory into Eastern Europe. In Asia we are taking steps to

compete more aggressively in this fast growing market, and plan further technical, sales, manufacturing and organizational efforts to re-establish Autoscope market leadership there. We believe our strong financial position along with our commitment to advanced technology will allow ISS to continue its global market leadership and profitability and are hopeful that all three market segments will contribute to revenue growth and earnings in 2006.”
