burglar alarm

A burglar alarm is an electronic alarm that is used to alert the home or business owner, and sometimes a monitoring company, of an intrusion into a once secured area.

A burglar alarm is one of the main components of home security systems and can range from a simple $10 device to a sophisticated whole-house security network.

The most basic burglar alarm is a simple electric circuit built into an entry way. They are divided into two basic categories, one being a closed circuit system and the other an open circuit system.
