At present, in the security industry, the GB28181 protocol is getting more and more attention, and it is becoming more and more common and stable. All security equipment manufacturers have basically supported the GB28181 protocol. Through the GB28181 protocol, the logic of obtaining the device's video, recording data, PTZ control, alarm detection, device cascading, etc. can be achieved, basically covering the needs of all industries.
This article talks about using the GB28181 protocol to connect security cameras to a private network or the Internet to achieve plug-in-free live broadcast on the web, mobile, and WeChat. The video stream obtained by the GB28181 protocol is a PS-encapsulated RTP packet and cannot be played directly by the web end. To achieve plug-in-free live broadcast on the web, the PS data packet must be decapsulated and then converted into live streaming formats such as RTMP/FLV/HLS and distributed to the client.
If you implement a complete set of GB28181 platform by yourself, you need to read the GB28181 standard protocol first, and first implement the SIP command interaction on the protocol. What is more troublesome here is that the implementations of various manufacturers, various types of equipment or platforms may be somewhat surprising, and all need to be done. It is a relatively long debugging process to achieve compatibility. The second step is to decompose the video stream and implement a set of streaming media distribution services to distribute the decoded video stream through the streaming media service. Finally, it is best for the web player to optimize reconnection, caching strategies, etc. In general, implementing an excellent GB28181 streaming media service platform is a project with a relatively large workload.
For companies that are not very experienced in video surveillance, it is recommended to directly choose a set of mature GB28181 streaming media services.
Here we recommend the liveweb streaming media platform. It is a set of GB28181 services that are in line with modern security and realize live broadcast and playback functions on all platforms such as web and WeChat. It has complete functions and is compatible with GB28181 equipment and platforms from major manufacturers. It can basically satisfy all security video needs. It supports users’ secondary development, function customization and other needs.
