Watchman
Like the Gatso, a constant stream of radar is emitted and speed is calculated as a vehicle passes through, triggering the camera. The difference with this camera is that it can monitor the speed of a vehicle before you pass it. There are also two types of camera built into the head unit. One is used to take an overview of the road and the other is used as a Number Plate Recognition System. You will see these cameras often accompanied by a "speed board" which displays the speed limit for that stretch of road.

at the road side, Watchman speed cameras use radar technology to measure
speed, a photo of the back of the vehicle is taken. The Watchman camera is
currently on trial awaiting type approval prior to a national installation
programme.
