Longitudinal virtualization device between video surveillance devices

Abstract

The invention discloses a longitudinal virtualization device between video surveillance devices. The longitudinal virtualization device between the video surveillance devices is applicable to a video management server in a video surveillance system. The longitudinal virtualization device between the video surveillance devices comprises a register management module, a storage management module and a flow balancing module. The register management module achieves redundancy management on register of front-end equipment between currently managed NVRs; the storage management module achieves redundancy management on storage of the front-end equipment between the currently managed NVRs; the flow balancing module achieves balancing management on the distributive flow between the currently managed NVRs. The longitudinal virtualization device between the video surveillance devices is applied to the NVRs and the front-end equipment. The hot backup of the NVRs in the video surveillance system can be achieved without additional equipment, and stability of the system is increased.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, in particular to a vertical virtualization device between video monitoring equipment in a video monitoring system. Background technique [0002] With the wide application of video surveillance services, the scale is expanding day by day, more and more video data is stored, and the front-end equipment managed is also becoming larger and larger, so the system has higher and higher requirements for stability. At present, network video recorder NVR (Network Video Recorder), as the mainstream network camera equipment on the market, mainly receives the digital video stream transmitted by network camera IPC equipment through the network, and stores and manages it, so as to realize the distributed network brought by the network. Architecture advantage. To put it simply, NVR can watch, browse, playback, manage, and store multiple network cameras at the same time. NVR can form a small monitoring...
