Videos of the VCN3000 Platform Cannot Be Found Because the Video Query Period of the External Domain Platform Exceeds the Limit

Publication Date:  2019-07-30 Views:  236 Downloads:  0

Issue Description

After the VCN3000 platform (with the version V100R002C20SPC212) is connected to the NetPosa platform through GB/T 28181+ protocol as the lower-level domain, videos r**ed by cameras on the VCN3000 platform cannot be queried on the NetPosa platform.

Handling Process

1. Register with the cameras on the VCN3000 platform and request live r**ding. If live r**rding can be performed, the communication between the VCN3000 platform and NetPosa platform is normal.

2. Run tcpdump on the VCN3000 platform to capture packets. During packet capturing, query r**ed video and export the PCG logs.

3. The obtained capture file shows that the VCN3000 platform returns an ERROR message after receiving the video query messages sent from the NetPosa platform.
