OK, bought a couple of the more expensive grandstream cameras and their DVR device. The cameras are really washed out by our security lights at night. I got the expensive night IR model hoping to capture traffic at night. But the ambient light is too much for the B&W IR mode and not enough for regular color daylight mode.
The thing that really bugs me is our inability to see the video remotely. If on site it works OK but if I log into the DVR it allows access but the screen is just black. No camera video is visible. Grandstream has not been helpful. So, shall I try another brand of camera? Have not tried any of the UBNT stuff. I have a cheap system from Harbor Freight that while is extremely low res and has noise on some of the channels actually works well enough for many things. (If nothing more than scaring away bad guys by the presence of the cameras.)
