EasyGBS is a video platform based on the GB28181 protocol. It has functions such as live video, video storage, retrieval and playback, PTZ control, alarm reporting, voice intercom, and platform cascading. Among them, the GB28181 protocol refers to the national standard GB/T 28181-2016 "Technical Requirements for Information Transmission, Exchange and Control of Public Security Video Surveillance Networking System". This standard stipulates the interconnection structure of the public security video surveillance networking system, the basic requirements and security requirements for transmission, exchange, and control, as well as the technical requirements for control, transmission process, and protocol interface. It is a national standard in the field of video surveillance.
The session channel of the GB28181 protocol uses the SIP protocol. The real-time audio and video on demand uses the INVITE method in the SIP protocol to realize the session connection, and uses the RTP/RTCP protocol (IETF RFC3550) to realize the media transmission. Simple understanding is as follows:
-
Device side: refers to the device running the client program of GB28181, such as IPC;
-
Platform side: refers to the GB28181 device or server that runs the server program, such as EasyGBS.
Today, I would like to share with you the query steps and signaling examples of the EasyGBS national standard configuration.
1) The EasyGBS server sends the national standard configuration query command to the device:
2) The device replies to the server and responds:
3) The device sends a message to the server, waiting to obtain the national standard configuration information:
4) The server responds and replies to the device:
In the actual video surveillance system, users do not directly interact with the front-end monitoring equipment, but interact with the video surveillance management platform EasyGBS. The role of the EasyGBS streaming media server is to receive and transfer audio and video streams, including receiving and monitoring equipment sending data packets carrying audio and video, and sending audio and video data packets to playback terminals (such as PCs, mobile phones, electronic large screens, etc.) or other platforms wait.
With the standardization and unification of the security market, the GB28181 protocol has become one of the mainstream standard protocols, especially in the fields of government, public security, and transportation, and is widely used. With its flexible and powerful video capabilities, EasyGBS has become a mainstream demand platform in the security market, and is used in project scenarios such as Xueliang Project, Bright Kitchen, Safe Village, and Safe City. Interested users can go to the demonstration platform for experience or deployment testing.
