How red-light cameras work

The video tutorial explains a traffic monitoring system used in New York and other cities. It consists of a high-resolution digital camera, a strobe light, a control box, and a video sensor. The system activates when motion is detected just before the stop bar after the traffic signal turns red. It captures two images: one before the vehicle crosses the stop line and another in the intersection with the red light on. A close-up of the license plate is also captured.
