Network video recorder cluster video monitoring system and method

Abstract

The invention relates to a network video recorder cluster video monitoring system and a method. The system comprises a network encoder, a plurality of network video recorders (NVR) and an NVR manager, wherein the network encoder, the NVR manager and each NVR are all connected with an IP network; each NVR supports a network storage protocol that the network encoder can directly access to audio / video data thereon so as to directly store the audio / vide data output by the network encoder in an encoding manner in the NVR; the NVR manager is composed of a mapping module and a monitoring module, the mapping module is stored with the mapping relationship between the network encoder and each NVR, and the monitoring module monitors and manages the audio-video data received by each NVR; and each NVR receives the audio-video data encoded by the network encoder by the IP network under the control of the NVR manager, records, responses to access requests from a client side or the network encoder, and queries or replays or stores the recording data. The system can manage the NVR in a cluster manner, solves the problems of performance and storage bottlenecks simultaneously and improves the whole system performance.

Description

technical field [0001] The present invention relates to video monitoring technology, in particular to a network video storage clustered video monitoring system and method that can be applied to large-scale monitoring platform systems, such as urban security systems. Background technique [0002] In the field of traditional video surveillance, a Digital Video Recorder (DVR) integrates the functions of digital video recording, network control, and hard disk storage. Among them, video digitization refers to converting the analog video signal of an external analog camera into a digital signal, and then converting these digital signals into a digital video stream arranged in a certain format through a video encoding module. These digital video streams are sent to network users through the network transmission module, and these digital video streams can also be stored on the hard disk of the device for future video recording information query. However, with the expansion of the m...
