1. Understand the CCTV surveillance system
The closed-circuit television monitoring system is an important component of the security technology prevention system.It is an advanced comprehensive system with strong prevention capabilities.It can directly observe all the conditions of the monitored place through the remote control camera and its auxiliary equipment (lens, PTZ, etc.),At the same time, it can also operate in conjunction with other security technology prevention systems such as anti-theft alarm systems.Make its prevention capabilities more powerful.The technical requirements for CCTV surveillance systems are mainly:The clarity of the camera, the transmission bandwidth of the system, the signal-to-noise ratio of the video signal, the format of the TV signal, the camera, etc.
2. Wide application of closed-circuit television surveillance systems
CCTV surveillance systems can monitor situations where people cannot observe them directly.But it can reflect the picture of the monitored and controlled object in real time, vividly and truly.And it has become an extremely effective observation tool for people to monitor in modern management.Since the CCTV surveillance system can observe many areas with only one person operating in the control center,Since the CCTV surveillance system can observe many areas with only one person operating in the control center,Even the unique function of remote areas is considered a necessary means for security work.The use of closed-circuit television monitoring systems can protect personal safety, save time and costs, improve efficiency, realize real-time command and dispatch, and process and save information.
CCTV surveillance systems have been increasingly widely used in public security,Finance (banks, postal savings, stock exchanges), industry and mining, traffic management (highways, national highways, urban transportation hubs), transportation (airports, terminals, railways, highway passenger stations), hospitals, commerce (shopping malls, supermarkets, jewelry Banks, wholesale markets), schools, residential property management, military, hotels (guesthouses, restaurants, office buildings), important material warehouses and security and other fields, it has become one of the symbols of modern management.
