DS2 speed cameras also known as SpeedMaster, Autovision or Autovision 2 are different names for a very similar system. These speed cameras are semi-permanent installations and can cover two lanes of traffic travelling in different directions. DS2 traffic cameras can be attended or left unattended whilst enforcing the speed limit.

DS2 speed camera sites work via three piezo strips either on top of the road surface or embedded within the surface of the road, the latter harder to spot. The piezo sensors are set approximately 1metre apart and are accompanied by a short grey post on the roadside. When in use the DS2 site is connected to the safety camera partnership van or unmarked car

. Autovision or Autovision 2 can then be used to provide video evidence of the speeding offence. Alternatively the Police will operate with a police car further along the road, and a message will be sent with details of the offending vehicles registration details to stop and issue the speeding offence. As vehicles drive over the three piezo sensors in the road, the DS2 camera equipment can calculate the vehicles speed. DS2 systems can be left unattended with the Autovision system recording vehicle details

How does a speed camera calculate a cars speed?

Very simply by measuring either the time between point A in the frame and point B or by taking two stills and measuring the difference between these and cross referencing it with the time between the two stills. The camera bit in speed cameras don't measure speed at all. Usually the camera is just a camera, an high-quality one with good automatic features. But the camera is connected to a radar, very similar to the handheld radar guns police also use/used. The radar is what measures the speed, and if it's above a certain threshold the radar triggers the camera to get some evidence of the event.
