What Is the Growth of Home Security?

Design

• Systems in a home are focused on three areas:
  Entry/exit: set through those access points that are normally used.
  Perimeter: includes all other doors and windows. Alarm sounds instantly.
  Interior: an alarm sounds when residents are away or in designated areas when home.

Types

• Hard-wired are more durable, but require drilling.
  Wireless are easier to install, but require batteries and batteries wear out.
  Hybrid include both types in applications that have a second story or detached garage.
  All installations feature stand-by power supplies in case of a power outage.

Monitoring

• Systems use line seizure whereby secondary devices are disconnected, and a signal is sent to the central station.

Devices

• Passive infra-reds detect any sudden increase in heat along with motion. Beams fan out over an area.
  Ultrasonics rely on a disruption of dispersed waves.

Costs

• Costs vary on owned or leased systems. Get three quotes. Monitoring is additional and monthly. A system saves on homeowners insurance.
