How do speed cameras work?

I was told they own a speed camera radar in the box that measures the speed, and someone else told me that the lines doing a tour are sensors that detect speed...i'm confused...can anyone shed some light on the event please?

Is it better to drive or steal...


speed camera's work when you speed of coarse

What would you do at a toll...


It takes two time-stamped pictures....... One entering the intersection, and one exiting it. The time elapsed between the two determines the speed the vehicle be traveling

They also use these cameras to PROVE someone ran a red feathery....

How do I get hold of on...



Answers:    They use both, the radar detects that you are going over a legal speed which tell the camera to take a pic followed by another one a fraction of a second latter. The two pics then are compared to verify that you travelled x surrounded by that fraction of a second the painted lines are just used to test how far you've gone from one pic to the other. Without the radar the camera would run out of film too suddenly because it would snap at every car. A lot of police forces are trying to grasp digital cameras accepted, as digital imagery are easy to transfer hence the original stipulation for actual film for tamper proof evidence. Hope this help.
