How to check the situation that the national standard platform easygbs equipment video cannot be accessed by grabbing packets?

National standard platform EasyGBS It has the function of accessing equipment video , Under normal circumstances , As long as the equipment recording is normal 、 The mechanism of the national standard is normal , You can access EasyGBS videotape , But in some cases , The device video cannot be accessed , This paper takes three common cases of packet capturing as examples , Let's introduce the reason why you can't access the device for video recording .

Situation 1 ：

The picture above is EasyGBS The platform sent a request to query the video , But when the subordinate returns the device video information, it returns error Error messages for , As a result, the equipment video cannot be recorded , This requires the subordinate platform to view the problem of device interaction .

Situation two ：

You can see the packet capturing result in the figure above EasyGBS The platform sends a request to the device to obtain the device video , But the equipment video sent by the subordinate is 0, This means that the device does not have video recording function , Or the video recording plan and memory card are not configured properly .

Situation three ：

This is a EasyGBS When sending the information of acquiring video to the next level , The subordinate returns 400 Error message , That is to say, the subordinate platform does not provide information to EasyGBS Platform push message , This will also lead to video access failure , This problem still needs to be investigated on the subordinate platform .
