How Does a Burglar Alarm Work?

A home security system is designed to act as a deterrent to criminals and to provide an accurate alert should there be an authorised intrusion into the building. An alarm system installed at a home, business, or other type of location, provides peace of mind to those who live, work, and own the property. Should a criminal enter the building, the alarms ring out and in some cases, an alarm system can also be attached to the emergency services for a fast response. This post will go into the details about what a burglar alarm is and how it works.

What is a burglar alarm?

A burglar alarm or home alarm system is an electronic system that detects and alerts any instances of unauthorised entry or criminal intrusion. Sensors linked to the alarm system are placed on doors, windows, they sense motion, the breakage of glass or other physical and audio activities that may point to criminal activity. These sensors trigger the system which sets off an audible alarm.

Different types of burglar alarm

Home alarm systems are either:

Wired

This is where the control panels and sensors are connected by wires and cables. There is a range of locations where a wired alarm system can be installed, although the need for cables to be present does restrict in some cases.

Wireless

The control panels and sensors are connected through radio signals and sensors are battery operated. They are easy to install, to change and add sensors and different layouts.

Direct/Unmonitored

A direct burglar alarm triggers lights and a siren designed to scare away intruders. This does work as a deterrent but does leave the home user to take responsibility for contacting emergency services.

Monitored alarm systems

Monitored alarm systems include a subscription service that connects to a professional monitoring service. When a sensor detects an intrusion, the company is alerted, the emergency services notified, and maximum security efforts deployed.

What are the components of a burglar alarm?

There are a few components that make up a burglar alarm system, including:

Control panel

The central processor that connects the different sensors, alarms, and in the case of monitored alarms, connects with the home alarm service. Control panels have keypads, touchscreens, and interfaces to arm and disarm the home security system.

Sensors

Sensors are placed around the building and entry points to detect movement or illegal activity and movement. Sensors are linked to doors and windows, motion sensors, glass break sensors, and smoke and heat sensors.

Alarms

Burglar alarms use loud sirens, bells, and other noises, over 120 decibels to scare away intruders and alert homeowners and neighbours to illegal activity.

Security cameras

Some burglar alarm systems have CCTV cameras connected to the system. Live feeds are often included in monitored alarm systems and recorded clips that can be used to prosecute intruders.
