DS-TMG022is a 2-ch loop-based digital vehicledetector. The device is designed with high reliability, and equipped with high performance microprocessorand channel sequence scanning technology. With functions of frequency self-adaption and full environment tracking, the device can track passing vehicles in a fast, effective and accurate way. The device integrates standard vehicle counting algorithm, and can be widely deployed in entrance/exit systems with traffic cameras.
