"Would you tell the contractor(S) that they are being watched at all times?"
I guess the contractor will know, since it will be me! /forums/images/graemlins/cool.gif
But there will be times when I can't be there, so it might come in handy for night security or something. Other than that, I guess it's just the geek factor! Nowadays you can do so much with computers, they have cameras that only record motion, and some that you can set to only record motion in certain areas, so you don't get lots of videos of blowing tree branches or leaves. One guy I know has this setup on his house at Lake of The Ozarks, his camera emails him the vid whenever it records, and he got one the other day. When he opended it, a deer walked across the screenview - pretty cool actually!
