Provides the GB 28181 gateway and the overall solution.I created
A video monitoring communication group 306754195 welcome to join.

GB 28181 defines the technical requirements for information transmission, exchange, and control of the video monitoring system. The control layer of the entire architecture adopts the SIP protocol, if a traditional video surveillance manufacturer wants to connect to a SIP network, a Protocol Gateway is required as a separate device,Converts a private protocol to the SIP protocol specification specified by gb28181, GatewayConverts the information data of the networked systems at different communication protocols to form interconnection between the two platforms,The video surveillance network system draws on the design concept of the NGN system, but it is different from the NGN concept, for example
P2P problems: In the NGN architecture, once a call is established, media transmission is directly between terminals. Due to its functional limitations, the monitoring system needs to use media gateway forwarding to consume a large amount of bandwidth, qoS mechanism is not guaranteed,How to Ensure end-to-end bandwidth is also a problem.
