How To Setup A Home Surveillance System Using FaceTime

Run this script on your Mac when you leave the house, you can call your Apple ID from your iPhone 4 phone number. The script will auto answer the FaceTime call, allowing you to check in on things. When you hang up, FaceTime will quit, and the script will continue to listen for incoming calls. When you get home, stop the script and FaceTime will no longer auto-answer your calls.

Clever.
