    Default How does photo radar work?

    How does photo radar work, and why don't radar detectors alert a user to it's presence? Does it use a different band of radar? How does it calculate a cars speed? Does it use radar at all?

    Some use radar some dont.
    The ones that dont (fixed speed cams) use embedded sensors in the ground. You pass over the first , then the second and the computer calculates your speed by time over distance. Then you get flashed and its over.

    quick, easy, and impossible to detect. (r = d/t --- rate = distance/time)

    probably why gps based systems are growing in popularity.
