2, real-time video, after-the-fact forensics: video surveillance images will be saved to the video command center of the traffic command center, as a basis for dealing with traffic accidents, violations, and even public security crimes.
Usually we often see that surveillance cameras are installed in front of traffic lights at road traffic intersections. Generally, such cameras include gun cameras, spherical machines, dual CCD fill-in cameras, and license plate road-specific cameras. Spherical machine: It can shoot in all directions. One machine can monitor many aspects, but the disadvantage is that it can only shoot the road surface where the head passes, but it can't be fixed. Spherical machines are generally located near the school and the three forks of the road.
Gun camera: A wide range of applications, depending on the choice of lens, can be remote monitoring or wide-angle monitoring. Generally, such surveillance cameras are applied to the periphery of traffic lights to capture vehicles across the line.
Dual CCD fill-in type camera: This type of camera has double-filling light and strong illumination capability. It is usually applied to the speed limit section and the speed limit bridge. It can clear the light at night.
Cameras for license plate roads: These cameras are well understood and are generally used near traffic lights to specifically capture license plates for red lights and illegal vehicles.
Regardless of the type of camera, it must meet the relevant requirements for traffic monitoring. Road traffic monitoring is all-weather monitoring, and the requirements for front-end cameras are relatively high. For traffic surveillance cameras, they must first ensure that they can be recorded 24 hours a day, that is, no matter how bad the environment, the camera should be able to maintain stable operation and the failure rate is low. Secondly, the performance of the camera is directly related to the ability to capture clear images under various conditions. Whether at night or under strong contrast conditions, the surveillance camera is required to clearly monitor the vehicle license plate and vehicle on the road. Type, color, etc.
[ Huaqiang Security Network News ] From the perspective of current urban development, the use of urban surveillance cameras is getting bigger and bigger, and it has become the “third eye†of traffic police. The surveillance cameras can grasp the monitored intersections in time and accurately. Vehicles, pedestrian traffic, traffic safety conditions, etc. around the road. In general, traffic surveillance cameras play the following two roles: 1. Real-time monitoring of road conditions: The surveillance cameras of each road section will transmit the real-time images of the monitored areas back to the traffic command center in time, so that the traffic commanders can grasp the traffic conditions of the intersections and sections in real time, for example, whether the traffic flow of the road sections and the traffic lights are working normally. Whether there are violations and traffic accidents to help the traffic control department take appropriate measures in a timely manner.
