Centurion Average Speed
Truvelo's average speed camera systems utilise a video system with Automatic Number Plate Reading (ANPR) digital technology. Consisting of a minimum of two cameras each fitted with infra red illuminators and fitted on gantries or poles above the road, they can work day or night. Average speed cameras work out the vehicles average speed, given the time it takes to drive between the two camera positions at a fixed distance apart.
The average speed cameras are fitted at the roadside a set distance apart to create a speed controlled zone, or where appropriate, groups of cameras can be linked to create a speed controlled network.
As vehicles pass between camera points their number plates are recorded from the live video stream by ANPR (Automatic Number Plate Recognition), whether speeding or not. Then the number plate read is sent to the processing station to have the them matched up. Because each image carries a date and time stamp, the computer can then work out your average speed between the cameras. There is no film used as it is all digital.
