What's a camera that shoots red lights like?

Its snapping principle is that when the signal light turns red, it will start snapping. In front of the intersection stop line 1-3 meters, the electronic traffic police snapshot system will take photos to collect evidence. When the front wheel of the vehicle passes through the stop line and presses on the induction coil, the first photo will be taken. When the rear wheel of the vehicle passes through the parking 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, the third photo will be taken.

The camera that captures the red light running needs to cooperate with the induction coil in the basement to capture the photo of the red light running. In other words, when the vehicle hits the buried magnetic induction coil, the electronic police will directly open the photo capture.

To judge whether the vehicle ran a red light, you need to take three different photos. 1 The photo was taken when the vehicle hit the induction coil through the stop line, the second photo was taken when the vehicle was moving forward, and the third photo was taken when the vehicle reached the opposite intersection and hit the opposite induction coil.
