According to our understanding, the CCTV monitoring system is an important part of the security technology prevention system, Cisco 400-051. It is an advanced and highly effective comprehensive system. It can be directly connected by remote control camera and its auxiliary equipment (lens, cloud platform and so on) to watch all the situation of the monitored place. At the same time, it can also be linked with other security technology protection systems such as burglar alarm system, so that its ability to prevent is more powerful 350-018 Lab. The technical requirements of CCTV are: the definition of the camera, the transmission bandwidth of the system, the signal to noise ratio of the video signal, the mode of the TV signal, the camera and so on. The transmission medium is a video cable. The control host is simulated. It is mainly used in high-grade offices such as banks and government agencies.
Video surveillance business has a long history and 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 digitalization and processing of image signals are becoming more common. Using digital image processing technology for dynamic monitoring and on-the-spot monitoring has become a reality, and has high sensitivity and reliability. Video monitoring system is widely used in many fields, such as financial system, traffic system, public security system, education system and medical system, because of its intuitionistic, convenient and rich information content. Traditional video monitoring technology is no longer suitable for the needs of the development of the times, and the network video monitoring system based on computer, network communication technology and intelligent image analysis as the feature of replica handbags has gradually become the development direction of the monitoring field.
At present, the large-scale network video monitoring service is still in the initial exploration stage. Network, digitalization and intelligence are the inevitable trend of video monitoring. In this big trend, there are many shortcomings in some key technologies of video monitoring and control. The main table is video storage, concurrent scheduling and billing. And classification of business integration.
