1. Logical Structure:
- Network video surveillance systems are composed of a central management platform, front-end devices, support systems, transmission networks, and clients. The central management platform plays a pivotal role in controlling signals and commands, facilitating media exchange, managing users, overseeing business operations, network management, billing, and statistical analysis. Components like the central management unit, media distribution unit, media storage unit, and business management unit collaborate in the monitoring center and media storage unit to accomplish tasks such as controlling signaling, protocol conversion, media scheduling, signal distribution, and storage.
2. Explanation of the System Components for Network Video Surveillance:
(1) Front-End Devices: Under the control of the central management unit, front-end devices, such as light bulb cameras, wireless cameras, and security cameras, are responsible for individual tasks of capturing video streams, audio streams, and collecting alarm information. In essence, front-end devices play a crucial role in signal acquisition.
(2) Monitoring Clients: Once front-end devices complete their data capture, monitoring clients are responsible for transmitting the collected audio streams, video streams, and alarm information to monitoring users. Subsequently, monitoring clients operate front-end devices based on instructions from monitoring users.
(3) Central Management Platform: The central management platform comprises devices like database servers, internet management servers, video access servers, video forwarding servers, and video storage servers. The central management platform is the core of the network video surveillance system, primarily handling functions related to user access control, user management, business administration, network management, and billing.
(4) Transmission Networks: Network operators provide the transmission network for the video surveillance system. The primary functions of the transmission network include video and audio transmission, command control, and the timely dissemination of other data information, including alarm messages.
