A remote access method and system for ipc

Abstract

The invention provides an IPC remote access method. The method comprises the steps that an NVR and a bound IPC negotiate a first IP address and a first port number, wherein the first IP address and the first port number are used for remote access; a web server establishing connection between the NVR and a client side host computer through the first IP address and the first port number; after connection is established, the NVR issues the first IP address and the first port number to the bound IPC, and after the first IP address and the first port number take effect on the bound IPC, and the web server annunciates an MAC address of the bound IPC to the client side host computer; the client side host computer sends remote access messages to an exit route device on one side of the NVR, the remote access messages comprise an MAC forwarding identification and the MAC address of the IPC to be accessed, after the exit route device on one side of the NVR receives the remote access messages, the messages are forwarded to the IPC corresponding to the MAC address when it is judged that the remote access messages carry the MAC forwarding identification. The IPC remote access method can enable the client side host computer to directly have access to the IPC.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to an IPC remote access method and system. Background technique [0002] With the development of network video surveillance, the demand for wide area network video surveillance represented by civilian video surveillance is increasing. In the WAN video surveillance system, the monitoring equipment is generally connected to the operator's network through the SOHO router, and users hope that they can access the monitoring equipment through the client anytime and anywhere. [0003] In the current wide-area video surveillance network diagram, the surveillance equipment manufacturer deploys a website server on the public network, and the user arranges one NVR (Network Video Recorder, network hard disk recorder) and multiple IPCs (IP Camera, network camera) at home. , users remotely manage NVR and IPC through the website client when they go out. Among them, the website server, website cli...

AI Technical Summary

Problems solved by technology

[0004] However, since the current IPC is mostly a third-party device, it cannot cooperate with the website server and website client to realize the process of traversing NAT, so users cannot remotely manage the third-party IPC through the website client

In order to allow users to remotely access the third-party IPC through the website client, in the existing technology, the third-party IPC can be accessed indirectly through the NVR, and then in this solution, the website client needs to access each IPC through the NVR for transit, which will Increase the performance pressure of NVR, and once the NVR has a single point of failure, all IPCs will be unable to be accessed by website clients
