Did he look like this?
Kind of jumping back to the topic of cameras and what not, I had a question for the experts on here:
We move into a new house next week, and there's a window next to the front door that's about 3" wide and 4' tall- my wife wants to put some "frosted glass" film on it so people can't just look into our foyer and see into the dining room/kitchen area. I'm on board, except then there's no way to look out and see who's at the front door. Aside from the obvious compromise- a curtain of sorts- is there a more inconspicuous approach, like a wireless camera with a small screen to mount next to the front door? I only ask wireless because I'm not sure we want to drill through the wall.
