1. Issue

Avigilon and Pelco (Motorola group) cameras can be added to Hanwha NVRs via ONVIF and show Connected/Online. The NVR also receives events/alarms, however live video is not displayed (black screen / no image / error icon).

2. Root Cause

KHQ confirmed the issue is addressed by adding / correcting RTSP BaseUrl handling in firmware.

3. Resolution

Apply the KHQ beta firmware listed below for the relevant NVR platform. After upgrade, the ONVIF-connected Avigilon/Pelco camera stream displays correctly on the NVR live view.
