Point-to-point cameras calculate the average speed of a vehicle by determining the time taken to travel between 2 points. If the calculated average speed exceeds the speed limit, the incident is accepted and sent for verification.
Cameras positioned at each ‘point’ take a set of digital images and also measure the speed of a vehicle at that location.
In-road sensors are used to detect the presence of a vehicle as well as the speed of the vehicle.
According to the Road Safety Act 1986, the point-to-point average speed formula is based on the shortest distance between 2 points and the time taken to travel between these points.
The shortest distance is measured by an approved surveyor. Surveyor certificates can be found with camera test certificates.
