Problems solved by technology

In daily maintenance, if the IPC fails and is replaced, the NVR cannot automatically identify the new IPC, and must be manually identified and set again, so the monitoring and management services of some key IPCs will be affected

Embodiment

[0025] The port corresponding method of this NVR and IPC comprises the steps:

[0026] (S10) In a distributed network with NVR as a node, the NVR is connected to multiple IPCs through a switching device, wherein the number of network ports of the switching device is not less than the number of IPCs; wherein, the network ports only refer to Network port for direct or indirect connection to IPC.

[0027] (S20) Explicitly number each network port of the switching device, and bind each numbered network port to different video channels in the NVR; the NVR initializes a corresponding logic for each video channel Interfaces, so that each numbered network port of the switching device is in one-to-one correspondence with the logical interface of the corresponding video channel.

[0028] (S30) Use VLAN isolation and identification for each network port of the switching device to form an independent connection channel from each IPC to the NVR. At the same time, the NVR maintenance inclu...

Abstract

The invention discloses a port correspondence method between an NVR and an IPC, comprising: in a distributed network with the NVR as a node, the NVR is connected to a plurality of IPCs through a switching device; and each network port of the switching device is displayed Each numbered network port is bound to different video channels in the NVR in one-to-one correspondence; each network port of the switching device is isolated and identified by VLAN to form an independent connection channel from each IPC to the NVR , so as to realize the one-to-one correspondence between physical ports and video channels. The present invention cleverly utilizes the switching equipment to provide the actual physical port, and combines the virtual local area network technology to match the logical interface of the NVR accordingly, and tags the transmitted message with a VLAN tag, thereby effectively realizing the isolation and identification of data transmission, thereby facilitating The orderly processing of many received video data on the NVR side effectively solves the problems of difficult to distinguish video data streams and inconvenient management in complex network deployment environments.

Description

technical field [0001] The invention relates to the technical field of video network applications, in particular to a port correspondence method between an NVR and an IPC. Background technique [0002] Digital Video Recorder, that is, digital video recorder, compared with traditional analog video recorders, uses hard disk recording, so it is often called hard disk video recorder, also known as DVR. Although it uses digital storage to record video, its front end is still an analog camera, and the transmission method between them is still through analog signal transmission. [0003] With the development of technology, the emergence of NVR (Network Video Recorder, network hard disk recorder) has changed the way of traditional video camera and video recording, making it develop towards the direction of networking. Its main function is through IPC (IPCamera, network camera) The digital video stream transmitted by the device is stored and managed, so as to realize the advantages ...
