I have all Hik cams with NVR and my hik PTZ is driving me nuts, so I would like to get the Dahua 2MP everyone here raves about. However, I wondering if I did, would it work via ONVIF on my Hik NVR or some stuff would be missing or not work? I do have a spare Desktop CPU in the garage and thought about Blue Iris to make things more compatible, but that seems like alot of work, especially if your not to techy.
