This alarm system was bought to protect my garage. The install was super simple, and the unit worked well in the house. The reason for my low rating was because they advertise a 450 ft range for the sensors, but at about 60 ft it would not work. It all fairness, I was told by a local alarm installer that none of the wireless units will transmit through aluminum siding. If you have any siding besides metal I assume it would work.
