The system is activated when motion is detected just prior to the stop bar AFTER the traffic signal has turned red. The camera system takes a series of two images.
The first image shows the vehicle before crossing the white stop line after the red light was illuminated.
The second image shows the violator in the middle of the intersection with the red light illuminated.
The license plate image is a close-up from one of the images captured.
Data including the time, date, and duration of the yellow and red lights is also recorded.
