Some of those products are great but designed for inside the home protection, which I don't really need. In all the years I've lived here, no one has ever rattled my door knob when I'm home, (I've rarely had anyone even knock on my door since it's a security bldg.). A burglar would either have to smash my door down or rappel in the window from the roof, both are pretty high-exposure for the thief.
I need a little camera that is cheap enough so that I won't be crying if someone pinches it from the hallway, (I'd hide it the best I can), I just want to catch the package thief. I've thought about leaving some dummy packages at door w a hidden tracking device, maybe my old iPhone w GPS enabled(?)
