What Is a Burglar Alarm System?
A burglar alarm (or intruder alarm) is a security system designed to detect unauthorised entry into a building or area. These systems can be:
- Wired or wireless
- Controlled via keypad, smartphone app, or remote fob
- Integrated with motion sensors, door/window contacts, and external sirens
When triggered, the system can activate a loud siren, notify you via app, or even alert a security monitoring service.
Wired vs Wireless Burglar Alarms
Wired House Alarms
- Hardwired into the property’s electrical system
- More reliable and tamper-resistant
- Best for new builds or major renovations
Wireless House Alarms
- Easy to install, ideal for retrofitting
- Controlled via mobile app
- Flexible for renters and small businesses

Key Components of a Burglar Alarm System
To build a reliable setup, you need more than just a siren. Let’s break down the essentials you'll need:
Alarm Panel
The control centre of your alarm system. It connects all devices and lets you arm/disarm the system. Panels like those in the Ajax Hub range also allow remote control via app.
Burglar Alarm Sensors
- Motion detectors (PIR)
- Door/window contact sensors
- Glass break detectors
- Curtain PIRs for targeted coverage
Alarm Box (External Siren)
A visible deterrent that sounds the alarm when a break in is detected. This often installed on an exterior wall and includes flashing LED lights to scare off intruders.
Burglar Alarm Battery
A backup power supply that keeps your system running during power cuts. Essential for reliability and peace of mind during power outages. You can read more about how and when to change your burglar alarm batteries in our handy guide.
