D-Cam uses a digital camera and is the only quality engineered speed and/or red traffic light violation monitoring system, which is the most versatile, modern, cost effective, accurate, fast and data-secure solution with built in automatic speed verification. The latest D-Cam can be connected to different sensor technology, used at mobile or permanent sites and digitally records speed and/or red-traffic light violations. It is the only instrument thatuses a unique secondary speed verification method, whereby the primary speed measurement can be verified.The vehicle is photographed always in the same position and recorded over verification markers together with time data imprinted onto the single picture. All required evidence for independent secondary speed verification are captured on this single image which reduces back office image validation and processing times.
