Experts called 5 types of cameras, to slow down before them is meaningless
A good reaction in these cases will not help the driver.
Experts called five types of cameras, before which it makes no sense to slow down. A good reaction in these cases, the driver does not come in handy, to avoid the penalty for exceeding can only be one way - do not violate traffic rules.
Medium speed cameras
The cameras of the Avtodoria system measure the average speed of movement on the road section. The camera removes the car when entering and leaving the site and calculates the time of travel. if the average speed turns out to be higher than the set one, you will have to pay a fine.
According to a similar principle, Avtouragan cameras operate. Two photographs also appear here, but only one camera takes both frames, “shooting through” a short stretch of road and calculating the speed of the car.
As a rule, mobile cameras on tripods are installed covertly.I saw this - it is useless to slow down, the camera detected the violation earlier. Radar cameras, unlike mobile ones, can be installed on buses, but most often such buses do not stand out among dozens of others, and the camera is hidden in them from prying eyes.
Cameras on the sidewalks
Chambers mounted on the sidewalks "do not care" with what speed the car goes. What is important is the fact of departure on the sidewalk. Such tracking systems do not observe the road, their “eyes” look only at the pedestrian zone.
Camera on zebra
Chambers of the system "Fast and Furious" fix violations related to the non-passage of pedestrians on zebras. The speed at which the car passed in this case also does not play a role, the main thing is that at the time of passing the car there are no pedestrians at the crossing.
Pit stop complexes are more than just a camera. This is a whole system that controls not only speed, but even driving style, passing this information from camera to camera and reporting violations to the nearest DPS crews. In this case, it makes no sense to reset the speed approaching the patrol car - the inspectors have all the “trumps” on their hands - full information about all the violations committed.
