What kind of probe will shoot violations?

1, electronic police

Installation location: generally at the crossroads.

Responsibilities: Monitor illegal behaviors such as running red lights, not following the direction, changing lanes illegally, pressing lines, retrograde, and motor vehicles occupying non-motor vehicle lanes.

Features: there is no hint when snapping.

2, bayonet (electronic capture)

Installation location: generally installed on national highways, provincial highways and expressways.

Responsibilities: mainly capture speeding behavior, and sometimes capture it without wearing a seat belt.

Features: Front snapshot, you can see the face clearly.

Principle: There are two ways to measure speed by camera, one is by coil installed underground, and the other is by radar on telephone pole. When the camera takes a normal snapshot, the flash will flash. If it flashes twice, it means that the overspeed has been photographed.

3. Illegal capture

Installation location: near the no-parking area.

Responsibilities: Capture illegal vehicles, capture retrograde and illegal lane changes.

Features: The camera can be zoomed, and generally it can see at least 200 meters.

4. Skynet monitoring

Installation location: various intersections, residential areas and other places that need to be monitored.

Responsibilities: The public security organs monitor the main roads 24 hours a day, eliminate hidden dangers of public security and better arrest criminals.

Features: pure public security monitoring, no snapshot function.

5. Traffic monitoring

Installation location: generally installed on the pole of electronic police or the pole of signal lamp.

Responsibilities: Statistics of traffic flow.

Features: No violation will be caught.

Photographers who violate the rules in China will have tips, such as snapshot tips, speed limit tips, violation tips and so on. With the help of all kinds of mobile phone applications, we can know the local traffic dynamics in time, understand the local sections that are easy to violate the rules and avoid violations.

Extended data:

The working principle of electronic police

In video shooting mode, there are no hardware facilities around the parking line. It relies on the automatic analysis and processing of video by equipment to capture more than ten kinds of illegal behaviors such as vehicles running red lights, driving in the opposite direction, pressing yellow lines, pressing lanes, driving in the left and right directions, and not driving in the prescribed lanes.

The shooting equipment of the electronic police illegal capture system can not only record illegal acts, but also have the function of identifying illegal acts.

According to Gao Kun, an engineer of the Traffic Police Detachment Research Institute of Urumqi Public Security Bureau:

When the device captures the red light, a virtual straight line will be set at the stop line of the recorded image. After the shooting equipment gets the signal that the signal light turns red, it will start the snapshot function and form two data streams at the same time. One data stream records the coherent influence and the other data stream records the required clear image.

Once a vehicle runs a red light, that is, when the red light signal is on, it passes through the virtual straight line set in the shooting equipment, then the equipment will record it, and at the same time form four ID photos and a complete and coherent evidence video.

After that, the equipment uses the method of frame-by-frame comparison to identify the car number. After at least ten times of recognition, the result with the highest recognition rate is output as the final number plate and uploaded to the electronic police snapshot record.

Gao Kun said that the first photo is that the vehicle has not pressed the line, but it can clearly show that the front is a red light;

The second picture is the picture of the car crossing the stop line without stopping after seeing the signal light is red, and the car body is pressed on the white line or about to leave the white line;

The third photo shows the vehicle moving forward after crossing the white line;

The fourth photo is a clear close-up of the license plate.
