How to judge a vehicle running a red light?

Photos of the front wheel of the car not crossing the stop line when the red light is on, photos of the car passing through the middle of the road and photos of the car driving to the opposite road;

When shooting the capture camera (commonly known as electronic police) that runs a red light, the shooting time is synchronized with the opposite red light, and there is no time difference;

Therefore, many car owners think that "the electronic police delayed for 3 seconds" to capture the picture is incorrect; The "3 seconds" often mentioned here actually refers to the "3 seconds" after the green light goes out, that is, the yellow light flashes for 3 seconds. After 3 seconds, the red light is on, and the electronic police will start immediately!
