Why cannot live video be viewed after NAT traversal is configured for the VCN500?

Check whether the corresponding port has been enabled on the firewall of the VCN500. If the port is disabled, log in to the VCN500 server to enable the port and check whether the fault is rectified. If the fault persists, contact Huawei technical support engineers for assistance.

What can I do if the VCN3000 client displays additional images during live video viewing?

The possible cause is that operations such as the action of linking live video viewing upon alarms trigger a new live video pane. Check configurations related to live video. Ensure that services are triggered according to configurations. You can check whether alarm linkage actions have been configured for the camera on the alarm management page on the C/S client.

What can I do if the VCN3000 client displays artifacts during live video viewing?

The possible cause is that the DCG to which the camera connects and the MU are located on different servers. Therefore, streams from the camera are transmitted between different servers, increasing the forwarding pressure of the service network adapter. To rectify the fault, allocate the DCG and the MU to the same server. Other possible causes include the network, camera, DCG, MU, and CU faults. For details, see the VCN3000 Maintenance Handbook.
