Yeah, I'll look into the setting as soon as I can get a chance. Unfortunately I'm slammed with work and still at the office. Depending on how late I get home tonight, I'll see if I have time to mess around a little with the settings.
What I can say for sure now is that (1) the window cam is currently forced-day and still doing this blackout thing (tried switching to auto, but it didn't stop the problem), and (2) the issue occurs in broad daylight with plenty of light hitting the cams sensor, so I don't think it's a lowlight issue. I recently changed the motion sensor sensitivity and threshold for multiple zones on both cams, but the problem existed on the window cam prior to me ever touching any of those settings (I set the motion detection setting immediately after installing the back door cam, so no benchmark on that one). I really haven't gone too crazy with NVR settings as I don't know much about it yet, and I haven't had much time to play around. I know first thing I did was max out recording resolution and FPS on the main and sub1 streams, and I set the "outdoor" or "street light" image setting for the cam out back with that glaring LED street light right in front of it. I already tried changing the outdoor/streetlight/auto/etc. settings to no avail, so I'm assuming that's not the culprit. I supposed I could try dropping the resolution and/or FPS, but that kinda sucks if I can't get the quality I'm expecting out of these cams.
May be a stupid question, but does RJ45 pinout wiring choice matter with these cams? I have all mine wired T-568B, and I assume that's what the monoprice cables are too though I haven't confirmed.
