Gatso speed camera

Gatso is a brand of speed camera invented by Maurice Gatsonides and manufactured by the Dutch company Gatsometer BV.

The Gatso emits radar beams to measure the speed of the vehicle. If it is travelling above the preset trigger speed, photographs are taken, using a powerful flash, to show the rear of the vehicle, its registration plate, and the calibration lines on the road.

Gatso installations are characterised by a series of white lines painted on the road. The camera takes two photographs with a known time interval between them (typically 0.5 seconds). The vehicle's position, relative to the white road markings in the two photographs, can be used to calculate the vehicle speed and is the only evidence admissible in court. The speed indicated by the radar unit is too unreliable to be used as the sole means of evidence as it is prone to error due to multiple reflections etc. Further, it does not distinguish between multiple vehicles in shot.

[edit] Deployment

In common with all fixed speed camera types operated in the UK by Safety Camera Partnerships (SCPs) under the National Safety Camera Programme (NSCP), there are deployment requirements for Gatso cameras used under that scheme. They must be marked yellow to make them visible, they must be located in places with a history of serious accidents, and where there is evidence of a speeding problem, or where there is local community concern^[1]. Cameras operated solely by the Police, outside of the NSCP schemes, do not need to comply with those requirements^[2]. The funding arrangements for SCPs will be changed in April 2007. SCPs will no longer keep the cash from camera fines, this will instead be given to local authorities directly, who can choose whether or not to invest it in these partnerships^[3]. Rules regarding visibility have changed but have not been abolished. [1]
