Is there a probe at the traffic light next to Sanshui Nan 'an gas station?

The monitoring of running a red light is public. If the intersection you are talking about has a red light detector, you can see if there is a monitoring device with the general shape as shown below. Because of the objective need of shooting, it is necessary to shoot the traffic lights before and after the stop line and when crossing the stop line at the same time, so it is installed in the sky a few meters behind the stop line at the intersection, and the direction of the monitoring head is roughly towards the stop line, and each lane corresponding to it has a monitoring head.
