DSS Pro V8.7 – Generic Event alarm shows "No Data"

Hi everyone,


I'm using Dahua DSS Professional V8.7 and sending alarms via the Generic Event API:


POST https://<DSS_IP>:18443/genericEvent/input

The alarm arrives fine in the Event Center, but the video/image panel always shows "No Data". I want to display a pre-recorded .mp4 clip from my local device inside the alarm panel no live camera linked.
Has anyone managed to get a video to actually show up in the DSS alarm panel through the API without a camera channel?
