How far is it for the traffic police to capture the speeding snapshot? In other words, how many meters from the vehicle to the capture lens before taking pictures?

Not necessarily, because the speed camera is usually used in conjunction with the speed radar, and the camera is triggered to capture when the vehicle is speeding.

Principle: Compared with traffic cameras, speed measuring cameras need one more device: speed measuring radar. Usually, the speed measuring radar will form a test belt about 5 meters long in the speed measuring area. As long as the speed exceeds the specified speed, the radar will feed back to the camera and take pictures in violation of regulations.

Speed camera has at least three independent working parts: camera, flash and speed radar. Speed camera generally has a set of equipment in each lane. In other places, the speed radar will be placed as a separate piece on the isolation belt, while the camera and flash are placed overhead.

The main function is to monitor the traffic flow, so that the traffic control department can observe whether the relevant roads can withstand the pressure of traffic flow, facilitate timely regulation and avoid traffic jams. This kind of camera is usually a camera with a flash, and there is only one set of equipment in one-way channel. This kind of camera has a very high shooting frequency, because every car has to record, so it will always be in a state of taking pictures.

2. Illegal cameras. This kind of camera is usually a set of monitoring equipment composed of rotating cameras, which is mainly used to photograph illegal parking, driving, emergency lanes and so on.
