Current Status of Network Video Surveillance Systems
Network video surveillance systems are composed of central management platforms, front-end devices, transmission networks, and client terminals. Let's explore these components in terms of their logical structure and functionalities.
Logical Structure of Network Video Surveillance
The network video surveillance system consists of central management platforms, front-end devices, support systems, transmission networks, and client terminals. The central management platform is responsible for controlling signals and commands, media exchange, user management, business management, network management, billing management, and statistical analysis. The central management unit, media distribution unit, media storage unit, and business management unit collectively handle control signals, protocol conversion, media scheduling, signal distribution, and storage within the surveillance center.
Description of Network Video Surveillance System Components
(1) Front-end Devices: Under the control of the central management unit, front-end devices such as cameras or microphones are responsible for capturing video and audio streams. Additionally, they utilize control interfaces to collect alarm information. In summary, the primary role of front-end devices is to complete signal acquisition.
(2) Monitoring Clients: After front-end devices finish capturing, monitoring clients transmit the collected audio and video streams, as well as alarm information, to the monitoring users. Subsequently, the monitoring clients execute relevant instructions from monitoring users to operate the front-end devices and other components.
(3) Central Management Platform: The central management platform comprises database servers, internet management servers, video access servers, video forwarding servers, and video storage servers. It serves as the core of the network video surveillance system, facilitating tasks such as access control, user management, business management, network management, and billing management.
(4) Transmission Network: The network video surveillance system uses network operators' transmission networks. The transmission network's primary functions include video and audio transmission, command control, and timely delivery of other data, such as alarm information.
