Gatso
Fixed Gatso speed cameras are rear facing. This is so the cameras 'flash' does not blind oncoming motorists. Unfortunately, this also means the cameras are not always viewable until the last second. The cost of installing a Gatso camera is approximately ?20,000. Gatso Cameras take two pictures, normally 0.5 seconds apart. This time interval should be indicated by the two photographs. If you have both photographs you can judge the distance travelled in the time and hence derive the speed of the vehicle at the time of the offence. Calculation, Number of marks passed , Interval between photos in
seconds, Distance between marks in feet
