Recently picked up 2 Swann SWNVK-870854T-US systems. These consist of NVR8-7085 paired up with 4 NHD-806 cameras. Early this week installed one at my home. Works perfectly. Today installed the other at my parents' home. NVR will not record. Shows an HDD error. On the IP channel menu, the 4 cameras I installed are showing up as Cameras 1, 2, 4, 5, even though they are plugged into POE positions 1-4. And, for whatever reason, in camera 3 position, status shows as "offline". Any advice on what measures to take is appreciated.
Cheers, Greg
