Thanks. On the front, right corner of the garage, I have 2 runs of Eth. One was for monitoring one-ish side of the front (depending on camera FOV) and the other was for the other side, but also to focus on the drive way which runs up the left side of the side load garage. The latter was intended to be a 6mm dome (ie catch license plate #'s and such of people that drive up). The other 6mm was for the rear house doors but to capture the deck stairs. I was on the fence about this one.

I have no issue going to f2.8 on the others. I switched to 4mm minimum based on the inputs if others. In some cases, potential ingress points are further from the camera so I figured from a personnel ID standpoint, higher focal length might be better.
