I couldn't find any firmware updates for the QC804-1 NVR. I just submitted a support request asking about the dual time periods for Color Settings.
I've also had one channel that remains black/white after boot-up. At first, all four channels booted up the same. Then this one channel started lagging. Now it has been powered up a couple hours and is still black/white. Its not the camera, I switched cameras and the problem stays with the cable. Its not the POE block, I switched the cables to different ports and the problem stays with the cable. I installed new RJ45 connectors on each end of the cable and removed the excess cable since I don't need the full 100 feet. Problem remains. Finally, I tried another cable (a short patch cable was all I had) and the problem went away. So, I would say I have a bad ethernet cable. This really sucks because it is fully installed, in the attic, inside the wall, inside metal conduit.
This system will be great once I get these two minor issues solved.
