I'm in the process of installing my cameras and so far have got my mini-dome installed next to the front door about 6' high so that I could get a good view of faces. From this location, however, I cannot see directly under the camera and cannot see what is directly on the door step. I'm debating whether I need yet another camera directly overhead on the overhang above the door looking down so that I could get a clear view of the doorstep area. Do you think it necessary to have a second camera just to see the doorstep? I'm debating whether it is necessary, but figured while I have the wall ripped apart it is easier to get a wire up there now than to have to rip everything open again later on.
