DAHUA OSD control

Yes OSD (on screen display) is associated with analog HDCVI cameras.
I had an XVR and a couple of CVI cams running up until last year. Never tried to use the OSD from the DMSS app though. Still have it connected to the network but turned off as I no longer use it.

Let me try and connect a CVI cam and see if my older version of DMSS can pull the OSD menu
