Lightweight Internet video gateway security access system and method

Abstract

The invention provides a lightweight internet video gateway secure access system, comprising cameras, video gateways, an access cloud server, a third party platform and clients. The video gateways areconnected with all cameras in local area networks through the local area networks. The video gateways, the access cloud server and the third party platform are in signal connection pairwise. The video gateways and the access cloud server are in signal connection with the clients. The invention also provides a lightweight internet video gateway secure access method. When users issue stream pull instructions to the access cloud server through the third party platform or the clients, the access cloud server receives and forwards the instructions to the video gateways and the video gateways control the cameras according to the instructions and directly send audio / video code streams collected by the cameras to the corresponding third party platform or clients, so signals and the audio / video code streams are transmitted separately, the lightweight low-cost social aspect monitoring video access is realized, and a bandwidth demand of the access cloud server is reduced.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a system and method for secure access of a lightweight Internet video gateway. Background technique [0002] Nowadays, in many places, there is a need to connect a large number of scattered cameras in the society to the Internet platform for centralized management and remote access. Because the amount of audio and video data is generally relatively large, it takes up more bandwidth. For example, 25 streams of 4mbps can occupy a full 100M bandwidth, and 250 streams can occupy a full Gigabit bandwidth, and the amount of surveillance video accessed by the social side is very large. It can reach thousands or even tens of thousands of cameras, so the demand for server network bandwidth is relatively high. [0003] Nowadays, the security demand has expanded to the social and Internet. A large number of security systems and equipment follow the GB28181 standard, which is formulated for ...

Problems solved by technology

[0003] Nowadays, the security demand has expanded to the society and the Internet. A large number of security systems and equipment follow the GB28181 standard, which is formulated for the security private network. Since the national standard access requires fixed IP addresses and ports at both ends, However, the IP and port in the LAN cannot be fixed. For example, the port is random, and the IP address is assigned by the operator. The situation of NAT (Network Address Translation) is not considered, so that the server on the Internet (GB28181 superior) cannot access NAT ( Network address translation) behind the camera in the local area network (GB28181 lower level); now many front-end cameras exist in the local area network behind NAT, the project of modifying the existing security system software and equipment is relatively large, so a large number of cameras are connected in the prior art The access scheme of accessing the Internet platform for unified management and remote access has the disadvantages of high requirements for servers and related equipment and poor compatibility with existing equipment

[0004] In the invention patent "A Method of Audio and Video Live Streaming Based on HTML5 Browser" with the application number 201610954750.1, it is proposed that the client and the anchor establish a communication channel through WebRTC to transmit video streams and audio streams and message transmission, and the client and the anchor After the client establishes communication, the client browser receives and processes the data; this method directly transmits the video stream and audio stream of the anchor to the client without completely relying on the server to push the stream, which greatly reduces the pressure on the network server, but the video The technical fields of live broadcast and video surveillance are different, and the transmission method of live video cannot be directly applied to the transmission of surveillance video
