There will be many cameras recording probes at traffic intersections. How to distinguish the role of the camera?

The camera recording probes at traffic intersections can be roughly divided into four types: ① traffic monitoring cameras that capture illegal activities such as running red lights, retrograde and changing lanes illegally; (2) Special surveillance cameras for shooting illegal parking; ③ Speed measuring point electronic induction monitoring camera; ④ Skynet surveillance camera of public security system.

The fixed position at the intersection, in front of and behind the traffic lights, is the first type of surveillance camera. The position of this kind of surveillance camera is generally fixed, and through the cooperation of multiple cameras, the traffic situation of vehicles in the corresponding lanes can be better photographed. So it was shot in a fixed lane, so after adjusting the position during installation, it will not be adjusted again. So when you see this kind of traffic light at the intersection, especially before and after the traffic light, you should pay attention to whether you have crossed the line.

On the street, who will? Shake your head and turn around. Our surveillance cameras are generally illegal cameras: in the no-stop area, a rotating camera can cover 270? , even 360? Parking dynamics within the camera range. This can save the camera and control the parking situation on the road more comprehensively. Moreover, if the camera rotates at a certain frequency, the vehicle still stays under the camera monitoring after many rotations, which is undoubtedly illegal parking, rather than a short stay?

The traffic test camera is very easy to distinguish, because there must be a warm reminder around this camera. Speed measurement ahead? Slogans like this, with red circles and white background, read speed limit information. For example, in the above picture, the speed limit is 35km/h, if it is exceeded, it will be recognized as speeding if it appears in the camera at a certain frame rate.

The background will implement the corresponding speeding penalty according to the detected information.

Basically, there are corresponding information tips around the second and third cameras.

There is also the last camera, there will be no other signal lights around, and there will be no tips. Although it is at the intersection, it seems to have nothing to do with us.

In fact, this is not the camera of the traffic system, but the public security system, which is responsible for monitoring the road dynamics and can be called when necessary: for example, if a child is lost, you can check whether it appears in this area, what is the trend and where did it go at last?
