 This is a true sad story for ADT, the leader in home security systems. My favorite dog, Oliver, was stolen from our garage recently. If I had a camera system installed in my home from ADT, I would have known exactly what car possibly pulled up in my driveway and stole my little friend. If I had a security system from ADT, my dog would still be here. I called ADT this weekend, and they're coming out in a few days to install a camera and a new security system.
