Burglar Alarm

A burglar alarm is a system designed to detect intrusion – unauthorized entry – into a building or area. They are also called security alarms, security systems, alarm systems, intrusion detection systems, perimeter detection systems, and similar terms.

Burglar alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders. Car alarms likewise protect vehicles and their contents. Prisons also use security systems for control of inmates.

Some alarm systems serve a single purpose of burglary protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with closed-circuit television surveillance systems to automatically record the activities of intruders, and may interface to access control systems for electrically locked doors. Systems range from small, self-contained noisemakers, to complicated, multi-area systems with computer monitoring and control.

Famous quotes related to burglar alarm:

    Put in hours and hours of planning, figure everything down to the last detail, then what? Burglar alarms start going off all over the place for no sensible reason. A gun fires of its own accord and a man is shot. And a broken-down old house no good for anything but chasing kids has to trip over us. Blind accidents. What can you do against blind accidents?
    Ben Maddow (1909–1992)
