Why is easycvr cascaded to the parent platform not displayed?

Video intelligent analysis and monitoring platform EasyCVR Since the launch of R & D , It has been popularized to major projects in a short time , such as EasyCVR Build a beautiful rural video monitoring system 、EasyCVR Build an overall solution for intelligent medical treatment, etc . One of the advantages is EasyCVR Access protocols are widely used , Moreover, it supports the cascade of national standard protocols .

EasyCVR Support the cascading of national standards to superior platforms , That is to regard the whole platform as a national standard equipment to connect with the superior platform . Feedback from on-site users EasyCVR After cascading to Haikang platform, the superior will not display .

Because the on-site situation requires high confidentiality , We can't know the situation of the superior platform , But according to the feedback phenomenon , We can see that the cascade is online on the platform side , And you can see the corresponding online channel .

However, there is no way to play on the superior platform , In this case, we can check the network data by capturing packets , The packet capture results are shown as follows ：

Here you can see EasyCVR The data returned by the platform cannot find the corresponding port , So it will lead to this phenomenon , The superior platform cannot receive messages . But after the investigation, no problems were found . At this point, we need to note that when cascading to other platforms , Some information of subordinate platforms needs to be configured in the superior platform .

The picture shows the settings required by the superior platform EasyCVR Platform information , That is the reason for the on-site problem . Here we need to fill in the information of the platform configuration center here .

Because there are many cascadable platforms , Compared with most conventional cascaded platforms , Some platforms need one more step when cascading , It needs to be checked here .
