Sorry to butt in here, but your fix to resolve the non-return to home position did not work for me. In addition, I changed the trigger to preset IVS rule from an intrusion zone, to a tripwire. Still no joy. The one common denominator for me is that all this is controlled by the NVR. In my case, a 5216-4KS2. Only place I can set this at, via the Web interface. I am running older firmware on it, 3.210.0003.0 Build date 2017-04-18. I am hesitant to update the firmware on the NVR, as it is running rock solid with this version. I have updated all cams involved to the latest firmware that is stable, reset them to factory defaults, and set everything up again from scratch. Still, the problem persists.
