How does the automated red light enforcement camera system work?
Each approach equipped with automated red light camera equipment will have a series of digital cameras installed near the roadway. The camera system is connected to the traffic signal and receives an active output when the traffic signal turns red. The system also uses radar detectors to measure the speed of cars just before they reach the intersection stop line. The camera is triggered to take the first photo when two conditions are met: 1) the traffic signal outputs an active red signal and 2) a vehicle approaching the intersection stop line is traveling above a pre-set minimum speed. The camera immediately takes a second photo to show that the vehicle proceeded through the intersection on red. The two photos include the date, time of day, time elapsed since the beginning of the red signal An electronic flash produces clear images of vehicles under all light and weather conditions. Neither the camera system nor the red-light camera system operators have control over the traffic signa
