When the easycvr platform cascades, there is an error prompt. What is the reason why the port is unreachable?

EasyCVR It is the most comprehensive video platform we support , It can support mainstream protocols, including national standards GB/T28181、RTMP、RTSP/Onvif agreement , And the private agreement of the manufacturer , Like Haikang Ehome、 The sea, SDK、 Dahua SDK etc. . The platform can provide live video surveillance 、 Cloud video 、 Cloud storage 、 Video retrieval and review 、 Intelligent alarm 、 Platform cascading 、 Intelligent analysis and other video services .

Some users are configuring National Standards GB28181 Access time , Connect the subordinate platform EasyCVR Behind the platform , stay EasyCVR Subordinate platforms are not displayed on the platform , Then grab the bag and check , The prompt port is not reachable .

Because such situations are often encountered on site , So today we will analyze the reasons and solutions in detail .

First , Carefully analyze the message data . From the message , You can see two problems （ As shown in the figure below ）：

1） When the user sets the port of lower level access , Configuration error ;
2）SIP ID It is also configured incorrectly .

For the above reasons , So lead to EasyCVR The platform cannot send reply information to subordinate platforms or devices through this port .

After modifying the docking parameters of the subordinate platform to the correct configuration , The subordinate platform can be in EasyCVR The platform is normally online .

The platform is based on the cloud edge end integration architecture , It can uniformly manage the front-end access equipment , It can also support the use of device trees to group devices 、 Hierarchical management 、 Equipment condition monitoring 、 Cloud operation and maintenance, etc , Realize centralized control and permission allocation of massive access resources . The platform can support multiple types of devices 、 Multi protocol access , Support for traditional webcams 、NVR、 Encoder 、4G Mobile law enforcement instrument and other video source equipment access , Maximize the compatibility of hardware devices . Interested users can go to the demonstration platform for experience or deployment testing .
