I have a Dahua DHI-NVR608-32-4KS NVR from Empire Andy. One of my 4K-Color-X cameras seems to have died the other day. It won't power on anyone (not a POE switch problem, tried different ports and a different switch). However, I never received any kind of notification that the camera went down. Is there a method in the NVR, or in the DMSS app or something to get notified if a camera goes down/offline? Seems like a pretty normal kind of request but I can't seem to find any setting for this anywhere? I would like it if, as soon as a camera is offline that I receive some kind of notification via DMSS app or via email etc. but can't seem to find this anywhere. Thanks.
