A security alarm is a system designed to detect intrusion, such as unauthorized entry, into a building or other areas such as a home or school. Security alarms used in residential, commercial, industrial, and military properties protect against  burglary ( theft) or  property damage, as well as personal protection against intruders. Security alerts in neighborhoods show a connection with diminished robbery.  Car alarms likewise help protect vehicles and their contents.  Prisons also use security systems for the control of  inmates.

Some alarm systems serve a single purpose of burglary protection; combination systems provide  fire and intrusion protection. Intrusion-alarm systems are combined with  closed-circuit television  surveillance (CCTV) systems to record intruders’ activities and interface to  access control systems for electrically locked doors. There are many types of security systems. Homeowners typically have small, self-contained noisemakers. These devices can also be complicated, multirole systems with  computer monitoring and control. It may even include a two-way voice which allows communication between the panel and monitoring station.
