Bottom left is actually 1.3mp. I do see it slightly blurry over the other cameras. It seems to me that there is enough light to force it to stay in color mode, but not enough for it to be a clear picture. I logged into the camera and turned it into night mode and it's very clear, but I think I'm going to leave it in color to match the other cameras. As for the one with the wall in it, I was worried about that one, but the guy did not want the entire neighbors property on his camera so while we were focusing it, we ended up with some wall. I told him if the IR's do not like it, than we need to move it. I think since the wall is far enough from the camera, it's not reflecting. My connection in China still has not received my turrets so I haven't even paid for them yet. I hate that it takes roughly a month to receive something once I place an order. I ordered four of them and the first 4 camera job that I get will be getting those four. If I think they look amazing, I'll probably order about 30 of them.
