Video monitoring system and method based on network file system

Abstract

The invention provides a digital video monitoring system which is characterized in that an encoding collection unit collects video and audio data in a monitoring site and serves as a client of a network file system to store the collected video and audio data to a memory cell serving as a server terminal of the network file system; a decoding play unit serves as a client of the network file system, and directly reads and plays video and audio data required to be played from the memory cell; and a center management unit manages and controls the encoding collection unit, the memory cell and the decoding play unit through a hypertext transfer protocol. According to the system, the encoding collection unit can be installed in any networking place, so that the problems of performance bottleneck caused by the center management unit, as well as single point of failure caused by center management unit failure are solved, and network flow brought by video and audio transmission are greatly reduced. Therefore, 'memory' and 'center management' can be separated in terms of region and manage sovereignty.

Description

technical field [0001] The invention belongs to the field of safety protection and network monitoring, in particular to a video monitoring system. Background technique [0002] Video Surveillance System (VSS for short) is an important part of modern security protection system. figure 1 A typical digital video surveillance system is shown, which can usually be divided into three components. The first link is video and audio acquisition and encoding equipment, such as IP cameras and / or cameras, and in some systems, traditional analog cameras can also be used with video and audio encoders (or video servers) to achieve digitalization Purpose. The second link is the storage, forwarding and system control of video and audio, such as the storage array (NAS / SAN, etc.) used to store video data, and the video management system (VMS, Video Management System, etc.) )Wait. The third link is video and audio decoding presentation and client control, such as monitors for watching videos...

AI Technical Summary

Problems solved by technology

Of course, some limitations can also be broken by establishing a domain name server (for dynamic IP) or setting the router to map the IP address and port (for intranet) to the external network, but this will increase the difficulty of installation and maintenance, and some even need to modify the existing Network facilities, not only high construction costs, but also high skill requirements for construction personnel and users

[0006] 2) All video and audio data must be managed and scheduled by the central management unit, so even if the network bandwidth and storage capacity are sufficient, the CPU computing power of the central management unit will still become a performance bottleneck

However, when the central management unit and the storage unit are separated geographically or in management sovereignty, the existing VSS system will pay twice as much network egress bandwidth cost
