[ Huaqiang Security Network News ] It is understood that the monitoring system has experienced three major stages in the security industry, both in shooting and monitoring. At the same time, the video surveillance of the core of the monitoring system is to shoot the scene with the camera. The video signal is collected to the central control department and displayed on the monitor. The video image is analyzed by the person and the computer to obtain a correct judgment. Traffic Hub Monitoring Due to the large number of objects that need to be monitored, the number of cameras that need to be installed is large, and the image storage is safe and reliable, ensuring that image storage is safe and fast. Transportation hub monitoring and selection must consider: simplify operation, maintain maintenance, protect existing investment, and expand. With the expansion of monitoring and construction of transportation hubs, it is very important to expand and protect users' existing investments.
After so many years of development, video surveillance has undergone three stages of evolution, mainly divided into three types:
The first is the analog video surveillance used in the early stage. The analysis and judgment of the monitoring picture are completed by human resources. The coaxial cable is used for transmission. The long distance (more than 500 meters) is generally transmitted by optical transceiver.
The other is the combination of analog and digital. The front-end analog camera outputs analog video signals, and the back end captures useful images through the computer for digital processing and intelligent analysis.
The third is IP intelligent monitoring. The front end is equipped with a professional analog camera + codec or IP digital network camera. This monitoring technology introduces a large number of computer technologies to assist people in collecting and managing all video information. The performance of the monitoring system has been obtained. Effectively improve. With the rapid development of IP intelligent monitoring technology, and with the development of computer and image processing technology, advanced and mature IP intelligent monitoring system will become the mainstream.
