How to distinguish highway cameras

Speed cameras are mostly installed on national highways, expressways and accident-prone sections, and are generally installed on shelves, which are easy to be recognized by the naked eye. But in some high-speed sections, these cameras will be installed under viaducts, which is difficult to identify. Therefore, friends who often take the expressway will slow down in advance and observe more when crossing bridge opening. It was captured from the front, and you can see the driver's face.

This kind of camera generally consists of radar and camera (including flash). When it takes a snapshot, the flash will light up. If the flash lights up twice, congratulations on winning the prize. Check the violation in a few days. Under normal circumstances, if the speed limit of this section is exceeded 10%, no penalty will be imposed.

The second category: electronic police

Install electronic police at intersections to capture red light running, line pressing, retrograde, occupying non-motor vehicle lanes, not driving in the direction, and changing lanes illegally. It was monitored by capturing the rear of the car, and he didn't give any hints when he captured the violation.

Matching this camera is a fill light. The fill light is usually off during the day and flashes at high frequency at night.

The third category: illegal capture

The illegal parking camera is generally spherical, which mainly captures the illegal parking behavior of urban no-parking sections, and can also capture illegal behaviors such as retrograde and illegal lane change. This camera can zoom and see things within 200 meters.

The fourth category: traffic monitoring

This kind of camera is usually installed on the pole of electronic police or signal lamp pole. Its main function is to count the traffic flow, and this camera will not capture traffic violations.

The fifth category: Skynet monitoring

This kind of camera is an ordinary surveillance camera, and it has no snapshot function. It is mainly used for public security organs to call out surveillance videos to inquire and monitor the whereabouts of criminals.

Characteristics of road monitoring camera

1, which integrates advanced optics, circuits, infrared lighting and temperature control technology, can clearly shoot fast moving objects such as license plates within the road monitoring range of 100 m and120 km/h.

2. The starting time of infrared light can be adjusted to meet different individual needs. You can adjust the menu through local or remote RS485.

3. The infrared brightness can be adjusted according to the exposure of customers, which effectively solves the exposure problem of traditional license plate cameras.

4. The start of the infrared lamp is synchronized with the day and night mode, and the start time of the infrared lamp is delayed to prevent external light (such as car lights) from causing the infrared lamp to switch on and off frequently.

5, advanced temperature control technology, so that the camera is not disturbed by external temperature, suitable for a wide range of regional environments.

6, special license plate solution, clear color 600 lines. Automatic white spot repair, reversing auxiliary line, motion detection, privacy screening and other functions are complete.
