The town, here in Florida, has installed Red Light Cameras at most major intersections. Actually a private company installed them and processes all the violations. Florida cars only have a rear license plate, nothing in the front. I understand how most of the system works. The system will sense a car that is moving through the intersection after the light has turned red. This can be with sensors in the road or sensors near the traffic light. The system will take a picture of the car that has passed through the red light. There can be be various times set up to allow a little leeway before the offender is caught.
The question I have is simple, it appears that the cameras face the oncoming cars and are angled down facing the road way. How do they get a picture of the rear of the car?
Picture a six lane divided highway with two additional lanes for left turns. The traffic lights are mounted on rigid poles with an arm that extends over most of that half of the road. The cameras and sensors are mounted on top of that arm and face down. There is no apparent camera that is capable of taking a picture of the car after it has passed through the red light .
So - How do they do it????
