What is the key to taking high-speed speed photos?

High-speed photography is mainly about shooting whether there is any violation of traffic regulations. Simply put, it is to take pictures of speeding. Speed cameras are used to measure speed and capture speeding vehicles. Also known as bayonet, there is usually a black square radar speedometer next to the camera.

there will usually be a big sign prompting you to enter the interval speed measuring section. On national and provincial roads, if you see the speed limit sign, there may be a fixed speed measuring point ahead. The specific location is between "5 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 5 meters away from the speed limit sign instead of next to it.

high-speed interval velocimetry is a very common acquisition system. The principle of interval speed measurement is that you can judge whether you are speeding by taking pictures twice in the speed measurement interval and comparing the time of taking pictures twice.

simply put, the interval speed is equal to the interval distance divided by the running time. For example, suppose that the mileage of interval speed measurement is 12km, just like the speed limit of this section is 12km/h, if the car drives within one hour or more, the average speed is less than 12km, and less than one hour is speeding.
