What is the camera at the entrance and exit of the high-speed service area? Tell me in detail?

anything lost in the service area should be compensated by the service area! As long as the car is on the highway, it will be charged! It's not safe to spend money to raise so many people! Therefore, the expressway should take full responsibility.

The camera in the service area is a bayonet set by the high-speed traffic police, which mainly collects vehicle information, and every vehicle will take pictures, and vehicles that violate the law will automatically report to the police in the background.
