Without a flash, the only evidence of speed camera on the outside of the car is a black rectangular box, which sends out the radar beam, about 30 cm by 10 cm, mounted on the front of the car. On the older models of the camera, and on rainy days or in bad light, a cable is used to link it to a box with a flash placed just in front of the vehicle.
ISA was born in France when Saad and Malaterre (1982) carried out their study of driver behaviour with an in-car speed limiter. Actually, they did not really test Intelligent Speed Adaptation, because the system did not automatically set the correct speed limit; instead drivers had to set the limiter themselves, and, rather like a cruise control, they could set it as they chose.
A traffic enforcement camera (also a red light camera, speed camera, road safety camera, bus lane camera, depending on use) is a camera which may be mounted beside or over a road or installed in an enforcement vehicle to detect motoring offenses, including speeding, vehicles going through a red traffic light, vehicles going through a toll booth ...

Speed limits in Australia range from 5 km/h (3.1 mph) shared zones to 130 km/h (81 mph). Speed limit signage is in km/h since metrication on 1 July 1974. All speed limits, with the sole exception of the South Australian school and roadworks zones, which are signposted at 25 km/h, are multiples of 10 km/h – the last digit in all speed signs is zero.
The speed of a vehicle occluded by (hidden behind) another vehicle cannot be measured. This occlusion issue does not apply to fixed speed enforcement devices that can be mounted on poles or gantries up to 5-6 meters / 15 -20 ft high using radar as detection method. Fixed and handheld lidar systems reliable up to heights of roughly 2 meters / 7 ft.

The first permanent average speed cameras were installed on the A13 in 2002, shortly after the speed limit was reduced to 80 km/h (50 mph) to limit noise and air pollution in the area. [73] In 2007, average speed cameras resulted in 1.7 million fines for overspeeding out of a total of 9.7 millions.
