Some considerations for GB28181 docking with the Hai Kang 8200 platform

Recently, a project in our side developed an NVR class equipment and Hoi Hong 8200 platform for GB28181 docking, before and after the toss of one weeks to complete, no other developers to provide technical support and documentation, we can only according to the national standard agreement to try, very uncomfortable.

Basically, there are a few places to be aware of:

1 after the first time the device sends the registration message, the 8200 platform will immediately come to query the device information and equipment directory, at this time must be prepared all the data to reply. Otherwise, the platform will not be asked again, causing the docking failure.

2 Device Catalog Response If there is a Chinese channel name, this response message does not need to be UTF8 encoded, the direct use of gb2312 can be.

3 platform issued by the PTZ control instructions, the gimbal device address is uncertain, the channel in use when the need to adapt to their own circumstances.

4 Video Search results, the name of the channel must match the name in the device directory, the total number of results can not exceed 200 (I finally decided to limit to 144), otherwise the platform will not be able to get results, and the protocol response is a number of OK, so people have no place to judge.

5 before the device restarts or shuts down, it is best to log off once, so that when you start the registration, the latest information to inform the platform.

Now found these need to pay attention to the matter, to share out to the useful people, less go some detours.

If you find other features, please leave a message.
