Photography, vehicle regulations

Illegal shooting can be seen everywhere. With the development of science and technology, there are all kinds of overloaded, speeding and illegal shooting. If you don't know much about these cameras, even if you are careful of the old drivers, there will still be "inexplicable" snapshots. Even if there is navigation, it will be reported in advance, but there will always be bad signal or delay.

Let's give you a general introduction to our common illegal cameras, hoping to help car owners to be vigilant and better avoid illegal behaviors.

electronic police

1) Installation location: generally on the L-shaped pole at the intersection.

2) Function:

① Monitor road traffic conditions, such as whether there is congestion, traffic volume, etc.

② Monitor traffic violations, such as changing lanes illegally, running red lights, not driving in the direction, pressing lines, going backwards, occupying bus lanes, etc.

3) Features:

Judge the violation by capturing the rear of the car, and trigger it by ground induction coil or video detection.

There is no hint when capturing, and the quality of capturing is high. At night, it also has the effect of LED fill light, full-time high-definition without code, and the recognition accuracy can reach more than 95%.

Illegal capture

1) Installation location: Generally, it is easy to illegally park and carry passengers on road sections or highway intersections with broad vision and no parking signs.

2) Function: specially capture illegal parking, and also capture illegal lane change and reverse driving.

3) Features: This camera is generally spherical and can be zoomed. In general, you can see at least 200 meters.

Bayonet (electronic capture)

1) installation location: generally on highways, national highways and other roads with speed limits.

2) Function: capture speeding behavior.

3) principle:

① There are two ways to measure the speed of this camera. One method is to rely on the ground loop installed underground, start timing when the vehicle passes through the first coil, end timing when the vehicle passes through the second coil, and calculate the speed.

(2) There is another kind of radar, which sends out radar waves to sense the speed of passing vehicles, and then takes pictures with a camera.

(3) The flash will light up when capturing. If the flash lights up twice, it means speeding.

4) Features: This camera captures the picture from the front with high definition, and even the face in the car can be seen clearly.

Therefore, if you encounter such a speeding violation, it will be difficult to find someone to replace you. Pay attention. Pay attention.

Layer velocity measurement

1) installation location: generally on highways, national highways and other roads.

2) Function: Two adjacent monitoring points are arranged on the same road section, and the average speed of the vehicle is calculated by the distance and time difference between the front and rear monitoring points.

3) Features: It is mainly to prevent some drivers from speeding without a camera and slowing down when approaching the camera.

When driving at high speed, pay attention to the start and end signs of speed measurement in roadside interval, and don't overspeed.

monitoring system

1) Installation location: intersections, main road sections, residential quarters, etc.

2) Features: This camera is only used for video recording and has no snapshot function.

3) Function: The public security system uses a large number of cameras set on the street to form a city monitoring network. It is an important tool for public security organs to crack down on street crimes, which can greatly improve the efficiency of solving crimes and is the strong backing of urban public security.

Flow monitoring

1) installation location: generally on the pole of electronic police or signal lamp pole.

2) Features: No snapshot function.

3) Function: Statistics traffic flow, providing data support for signal control. For example, the traffic lights at some intersections are intelligently controlled according to real-time traffic flow detection.
