There are speed cameras now in most places that are busy intersections. Speed cameras are expensive and are usually not found in small towns or small municipalities.
Panasonic, Sony, LG, AOS Technologies, Optronis, Photron, Vision Research and Fastec Imaging make high speed video cameras. These cameras are used in television, science and also for defense systems.
