The Sonic Entry Alarm System includes 4 separate alarms to be installed on doors, windows, or cabinets. The four adhesive-backed alarms install to anything that opens-doors, windows, or cabinets-and operate independently of one another rather than from a central system to allow household breeches to be pinpointed. Great price on an easy solution.
