After EasyCVR is locally connected to the national standard device to map the public network, the local device cannot play and cascade the solution

TSINGSEE Qingxi Video's platform (EasyGBS/EasyNVR/EasyCVR) can support the cascade function. The platform can be cascaded to the upper-level platform through the national standard GB28181 protocol, or it can be used as the upper-level platform to allow the lower-level platform to cascade through the national standard GB28181 protocol.The cascading function is very important in security and other scenarios. It can realize the interconnection and sharing of data, flexible scheduling, break the data island of the system, and allow information to be efficiently exchanged.

According to the needs of the user scenario, the equipment protocols previously accessed by the EasyCVR platform are all connected to the same network segment LAN through the national standard GB28181 protocol. The user EasyCVR server uses dual network cards.The local network card is mapped out, but the national standard equipment connected in the early stage cannot be changed, so the current requirement is that both the local area network and the public network need to be connected to the equipment and need to be cascaded so that normal video viewing can be performed.

When configuring, the technicians will open the public network inflow according to the normal operation in the past, fill in the public network for wan_ip, and fill in the national standard IP of the internal network for host IP.

After configuring the easycvr.ini file normally, restart the service and find that the national standard channel registered in the intranet cannot be played normally, and the cascade cannot be registered normally.

So I captured the packet and checked, and found that when the intranet national standard registration request was played, a stream was sent to the intranet network card, but the cascade did not receive the message.Through consulting users, it is known that when using the internal network, the national standard network card cannot access the external network, and the public network IP is bound. If the network card is another one, it can access the external network.

According to the on-site network environment, the technician changes the configuration strategy, reconfigures easycvr.ini, does not fill in the public network address for wan_ip, opens the traffic, fills in the public IP for the host IP, and fills in the traffic IP in the device editor for the national standard registration of the internal network.

After adjusting the configuration according to the above method, the user's intranet national standard registration channel can also be played normally, and the cascade is also registered and launched normally.The EasyCVR platform can meet the diverse needs of users in complex network environments with flexible configuration capabilities.

EasyCVR has strong scalability, flexible video capabilities, and easy deployment. It supports massive video aggregation management, and can provide video surveillance live broadcast, cloud recording, cloud storage, video retrieval and review, intelligent alarm, platform cascade, intelligent analysis, etc.video service.In terms of access protocol, it not only supports the national standard GB28181 protocol, RTSP/Onvif, RTMP and other standard protocols, but also supports HIKSDK, Dahua SDK, Hikvision Ehome and other manufacturers' proprietary protocols and SDKs, and can distribute RTSP, RTMP, FLV, HLS, WebRTCand other formats of video streams.Interested users can go to the demo platform for experience or deployment testing.
