I connected a Hikvision camera DS-2CD2T85FWD-I8 to my NVR and instead of a connection symbol, it showed a ? mark which indicated there was an error. I can see the picture and can set up the camera for 3840 x 2160 resolution on the browser using the 65000 port but then when I look at the browser settings which shows my 3 cameras, I see the 8 mp camera is only recording at 640 x 480 and I can't select anything higher. My other 2 Hikvision 3 mp cameras can be selected to record at 1920 x 1080. Has anyone ever seen a connection error ? on the tv screen which is showing me the Hikvision program? I've done a software reboot back to the factory default using the browser but it still shows the error on the tv screen and low 640 x 480 resolution.
