Is the high-speed tachometer pressed?

High-speed speed measurement will shoot the compaction line, and use the speed camera to capture speeding vehicles. Also known as the bayonet, there will be a black square radar speedometer next to the camera, which is easy to distinguish. Cameras can be divided into digital cameras and analog cameras. Digital cameras can convert analog video signals generated by video acquisition equipment into digital signals, and then store them in computers.

High-speed cameras will shoot pressure lines. It should be pointed out that:

1. On the national highway, if you see the speed limit sign, there may be a fixed speed measuring point ahead. The specific location is between "500 meters after the starting point of the speed limit sign and the lifting of the speed limit sign or the next speed limit sign", that is to say, the fixed speed measuring point will be set 500 meters away from the speed limit sign, not beside it;

2. The general camera will record the speed of the car, take pictures according to the speed, and identify the license plate number of the car, so that as long as it is kept within the specified speed, even if it is taken, it will not be recorded;

3. Velocity measurement photography adopts interval velocity measurement. Working principle: According to the "average speed" to calculate whether the vehicle is speeding, the two-point snapshot method is adopted.
