Do It Yourself Motion Sensing Alarm

I loved the simplicity and effectiveness of this inexpensive do-it-yourself alarm from GE.  The GE Ceiling Mounted Motion Sensing Alarm is battery powered and just attaches to the ceiling of a hallway, entrance way or any room you wish to protect.  Arm it with the included keychain remote, and if someone enters the area it sets off a loud alarm.  The alarm looks like a smoke detector although it is not a functional smoke alarm.    Simple, effective and installs in minutes.  Perfect for homes, businesses, dorm rooms, cottages, bunkies, etc.
