Image Sensing Systems Announces First Quarter Financial Results

Saint Paul, Minn.,- April 27, 2006-Image Sensing Systems, Inc. (ISS) (NASDAQ: ISNS), announced today financial results for its first quarter ended March 31, 2006, marking the sixteenth consecutive quarter of profitability for the company.

Net income for the quarter increased 26.7% to $503,000 ($.13 per fully diluted share) compared to $397,000 ($0.10 per fully diluted share) for the comparable period in 2005. Revenues for the first quarter were $2,589,000, a 21.7% increase from $2,127,000 for the comparable period a year ago. Revenue from royalty income increased 28.2% to $2,176,000 from $1,697,000 in the first quarter of 2005 and reflects the continued success that ISS’s North American distributor, Econolite Control Products, Inc. (ECPI), has had in selling Autoscope products in the United States and Canada. International sales for the first quarter of 2006 were $413,000 compared to $430,000 in the first quarter of 2005. Operating expenses increased 31.4% as the company added engineering resources for new product development and incurred added general and administrative expenses.

Jim Murdakes, Chairman and CEO said, “We continue to be pleased with our North American partner, ECPI, for its continued solid performance in the North American market. International sales were flat as we were unable to complete shipment of a large order for Korea in the quarter, which would have increased our sales substantially. The shipment was completed in April and will be reflected next quarter. First quarter sales in the European market are typically slow and this was true again for 2006.”

Headquartered in St. Paul, Minnesota, Image Sensing Systems, Inc. combines expertise in image processing, hardware and software engineering, and communications to develop video vehicle detection systems for traffic management and control applications. The Autoscope vehicle detection system is the world leader in video detection for advanced traffic management systems for highways, tunnel incident detection, intersection control, and traffic data collection.
