The last "hole" is my garage door opener. Very frequently when I've left the house for extended periods (over 24 hours), I'll come home to find the remote key pad with the cover open as if it were used. I've rigged the garage door before and I don't think anyone has ever entered through it, but I don't doubt someone has been plugging in random numbers trying to get in.
I'm in a good neighborhood with nosey neighbors, so I don't expect more than "industrious" teenagers at work. But, I would like to surreptitiously see who's doing it without them seeing me. I'm on a typical residential street, so I don't have options like a wildlife camera. Again, I'm not interested in installing some whole-house security camera system. What I want is a localized system that I can put in place to detect when someone is at the keypad using it and preferably record that content while I'm away. Any ideas, Slashdotters?
