This is more of a programing idea I guess you could say, but I'm not sure where else to put the thread. The idea would be to have a camera at your front door or even eye level near the door and incorporate some form of facial recognition software to turn on when it detects motion. This would allow two things, one easy automation of deadbolts and or alarm systems. Obviously this would be a very high risk, giving someone who looks like you would be able to unlock your door by just walking up. But on a more social aspect of it, it could alert you of friends arriving and announcing them over your speaker system in your home. This could allow you to unlock a door for them if you are all the way across the house using voice commands and/or remote deadbolts. Obviously this person would have had to been there before, or I'm not sure if you could base the facial recognition off of a photograph. The idea came from the announcements of telephone callers over speakers systems. With the price of facial recognition software coming down in price drastically (Google's Picasa, Xbox 360's Kinect, ect) and the versatility of Mister House and other X10 controlled software, this seems do-able. I'm not sure if I'm just dreaming at this point, or if this is actually something that could be done. Any ideas would be great.
