According to our understanding, the CCTV monitoring system is an important part of the security technology protection system, Cisco 400-051 It can directly watch all the situation of the monitored place through the remote control camera and its auxiliary equipment (lens, pan tilt, etc.), at the same time, it can also be linked with the anti-theft alarm system and other security technology protection systems to make its prevention ability more powerful 350-018 lab. The main requirements of signal-to-noise ratio, video camera and signal transmission system are: signal to noise ratio, video camera, signal transmission system, etc. The transmission medium is video cable. The simulation processing is carried out by the control host. It is mainly used in banks, government agencies and other high-end places.
Video surveillance business has a long history, which is widely used in the field of security. In recent years, with the rapid development of digital image processing technology and digital circuit technology, the digitization and processing of image signal become more common. It has become a reality to use digital image processing technology for dynamic monitoring and on-site monitoring, and it has high sensitivity and reliability. Video monitoring system is widely used in financial system, transportation system, public security system, education system and medical system for its intuitive, convenient and rich information content. The traditional video monitoring technology has no longer adapted to the needs of the development of the times, and the network video monitoring system based on computer and network communication technology and characterized by intelligent image analysis has gradually become the development direction of the monitoring field.
At present, the large-scale network video monitoring business is still in the initial stage of exploration, networking, digitization, intelligent is the inevitable trend of video monitoring, and for this trend, the current video monitoring in some key technologies, there are many deficiencies, mainly in video storage, concurrent scheduling, billing, hierarchical business integration and so on.
