The main function of the road surveillance camera in the intelligent traffic system is to collect the video image signal, and transmit the image signal through the transmission line to the signal acquisition host for image storage, analysis and processing. The main applications are summarized as follows: Road conditions monitoring The front-end camera transmits the real-time image of the monitored area to the traffic command center via the transmission line, and the traffic commander grasps the traffic conditions of the intersections and road sections in real time. For example: traffic volume and signal status of the road section. , violations of motor vehicles and traffic accidents. This information can help the traffic management department to take appropriate measures and handle the plan in a timely manner. It can promptly release information by broadcasting and television media and in front of the traffic-induced display screen to inform drivers and pedestrians on the road for effective traffic guidance. 
First, road surveillance camera product selection guide
The road surveillance camera system uses cameras and other devices to directly view all the conditions that have occurred on the monitored sites and targets on the monitor. The content of the image information of the monitored place and the target can be transmitted to the recorder for recording.
Camera: The optical signal of the subject is converted into an electrical signal, which is then sent to the transmission section of the system for transmission. The camera direction and lighting conditions should meet the following requirements:
1) The camera should be installed in a place that is not easily affected by external damage near the monitoring target. The installation location should not affect the on-site equipment operation and normal personnel activities.
2) The camera lens should avoid direct light and ensure that the target surface of the camera tube is not damaged. Within the field of view of the camera, there must be no object that blocks the surveillance target.
3) The camera lens should be aligned with the monitor target from the light source and should be installed with backlighting. When backlight installation is required, the contrast of the monitor area should be reduced.
Camera: There are two types of color cameras: black and white. Camera target specifications are: 1 inch, 1/2 inch, 2/3 inch, 1/3 inch, etc.
Second, construction, installation points
1) The road surveillance camera should be installed near the monitoring target where it is not easily damaged.
2) The road surveillance camera lens should be aligned with the target of the light source.
3) The road monitoring camera lens should avoid direct light to ensure that the target surface of the camera tube is not damaged; there must be no object that blocks the monitoring target in the field of view of the camera.
Talking about the Development Trend of Road Surveillance Cameras and Precautions for Purchase and Use
Along with the development of the domestic intelligent transportation industry, the application of road surveillance cameras in the transportation sector has further deepened and continues to play a major role. In order to use effectively in various complicated road environments, the quality of the captured video images is clearer and more accurate. The performance requirements for road monitoring cameras are getting higher and higher, and the product form is also more specialized and serialized. In recent years, new high-tech products such as high-definition cameras, infrared cameras, automatic tracking cameras, network cameras, high-light suppression cameras, and wide dynamic cameras have been introduced in accordance with various application requirements.
