recordings are made automatically of the output from the camera or cameras surveying the vehicle and the place where a contravention is occurring,

there is used a secure and reliable recording method that records at a minimum rate of 5 frames per second,

each frame of all captured images is timed (in hours, minutes and seconds), dated and sequentially numbered automatically by means of a visual counter, and

where the device does not occupy a fixed location, it records the location from which it is being operated.
