What about the camera that ran the red light?

the appearance of a rectangular box.

its snapping principle is that when the signal light turns red, it will start snapping. When the vehicle runs a red light 1-3 meters in front of the stop line at the intersection, the electronic traffic police snapping system will take photos to collect evidence. When the front wheel of the vehicle passes through the stop line and presses the induction coil, it will snap the first photo. When the rear wheel of the vehicle passes through the stop line and presses the induction coil, the camera will capture the second photo; When the vehicle reaches the opposite intersection and hits the induction coil, it will capture the third photo.

The camera for capturing a red light running needs to cooperate with the induction coil in the basement to capture a photo of the red light running, which means that when the vehicle hits the buried magnetic induction coil, the electronic police will directly turn on the photo capturing at the same time.

in order to determine whether the vehicle is running a red light, it is necessary to take three different photos. The first one is that the vehicle will take a picture when it passes the stop line and hits the induction coil, the second one is that the vehicle continues to drive forward, and the third one is that the vehicle reaches the opposite intersection and hits the opposite induction coil.
