Embodiment Construction

[0028] figure 1 It is the physical architecture diagram of the network video surveillance system. The network video surveillance system includes a front-end subsystem, a client subsystem and a central service platform.

[0029] The front-end subsystem is a subsystem composed of all equipment used for audio and video information, alarm information, control information acquisition, buffering, encoding, forwarding, and possible storage. It includes: camera, PTZ, video server, alarm input and output devices, and local digital video recorder (DVR), etc. The important alarm information mainly comes from the alarm of the I / O serial port and the alarm generated by the video server based on image motion detection.

[0030] The client subsystem is a device used to browse and control remote video and systems. Including real-time and historical audio and video decoding and playback, user management interface, service opening and management interface, system maintenance interface, alarm...

Abstract

This invention relates to a third generation network video monitor system which interconnects the front subsystem, the customer end subsystem and a central service plat form by the IP loading network, among which, the central service platform is composed of the national management center, the provincial / regional management center and the local center. The telecommunication service merchants provide network video monitor safety and warning service to the public.

Description

technical field [0001] The present invention generally relates to a video surveillance system, and in particular to a third-generation network video surveillance system based on embedded technology and based on network and communication technologies. Background technique [0002] The development of my country's network video surveillance technology has gone through the following three stages: [0003] 1. Early closed-circuit video surveillance system. It evolved from security products and is the first generation of analog video surveillance system in my country. [0004] 2. The PC-based plug-in video surveillance system began in the mid-1990s. Although digitalization has been initially realized, the second-generation video surveillance system is still only used as a security product for daily monitoring in certain industries due to technical deficiencies such as image quality, stability, and remote transmission monitoring. [0005] 3. The network video surveillance system...
