Hello: I have the 4 4k Camera / 8 Channel LNK series NVR from Costco. I installed the system and it works well. My issue is that the NVR is in a closet, and to access the NVR settings, it does not seem to work with the Client 12 software. I can see all 4 cameras via directly plugging a monitor into the NVR I can see all 4 cameras via app for android and apple while on / off my network I can see all 4 cameras via web browser by typing in the ip address of the NVR on my downstairs & upstairs PCs. But if I try to use the FLIR Client 12 software on both upstairs PC (Win 10) and downstairs PC (Win 7), I can only see 1 camera (Channel 1). I can't access the other 3, they are grayed out on the screen, and don't show anything, but they show up on the "list" Submitted a support ticket over two weeks ago with no response. Any ideas? Thanks in advance! Browser showing all 4 cameras. Flir Client 12 with only Channel 1; other 3 grayed out. Flir Client 12 showing all 4 cameras being recognized.
