it. I have never had this problem with any other Trendnet NVR (NVR208 POE) that I own. These NVRs are fully password protected from the factory and cannot be reset without Trendnet Technical Support providing you with an unlock code. Once unlocked they work very well, I have 4 Trendnet cameras, 4 Uniden cameras and 2 Amcrest cameras connected to this NVR with a D-Link DES-1210-28P (POE) switch to switch the cameras To be powered, Uniden and Amcrest cameras use ONVIF protocol and they work fine, all PTZ controls work and detect motion, so bottom line if you don't mind waiting a few days then it's a good deal , and it comes with a 4TB digital surveillance drive as a plus.
