GB GB / T28181 proposed by the Ministry of Public Security Technology Information Bureau, the standard specifies the city network alarm monitoring system, information transmission, switching, control interconnect structure, communication protocol structure, transmission, switching, basic requirements for control and safety requirements, and technical control requirements, the transmission protocol interface processes and the like.
GB / T28181 cascade not only between devices, the system also includes a cascade, it is not contradictory. The network cameras through ONVIF NVR access protocol, NVR by GB / T28181 standard access platform, or network cameras by cascading ONVIF protocol between the access platform, the platform by GB / T28181 specification. So ONVIF / PSIA, and GB / T28181 often also play a complementary role, can make the selection of equipment, promote broader, better promote the safe city network, high definition process.
When RTSP or Onvif like LAN monitoring other IP video needs to transfer public broadcast (rtmp / hls / ts) and the like, such as scenic monitor TV or campus monitoring Air can achieve multiple camera angles switching function; if the cell, Park, enterprises traditional monitoring and other institutions linked to the Ministry of Public Security Skynet system may involve various protocols stream into each other.
D300plus / pro This product is targeted to solve the problem GB / T28181 protocol interworking, it is a high-performance embedded multi-function media gateway equipment, set the streaming protocol conversion, streaming media distribution services, multi-channel video decoding, video split screen functions in one core, may be applied to different systems, different manufacturers, different types, different video content encoded video format conversion, protocol interworking, the decoded output, divided display, but can also achieve concurrent access capability of less than 100 streaming media server functionality. Air turn be used to monitor, to monitor transfer GB28181, RTSP turn RTMP, UDP transfer the RTMP, public security monitoring access network.
