Speed Camera Technology

These cameras come in many forms, some free standing on poles; others mounted on bridges or overhead gantries. 

The most common and probably most wide spread camera is the red light camera, which is a common sight at intersections in cities and large towns.

Dual speed and red light cameras are used in the Northern Territory, South Australia, the Australian Capital Territory and Victoria. They detect speeding at the intersection as well as running a red light.

Police also use other technology that does not rely photographs being taken of an offence, typically where officers enforce the speed limit in person.

Mobile systems can be vehicle-mounted, hand-held, tripod mounted or even concealed in items such as garbage bins. In vehicle-mounted systems, detection equipment and cameras can be mounted to the vehicle itself, or simply tripod mounted inside the vehicle and deployed out a window or door.
