Intruder Alarms chosen for your property

Alarm coverage for doors, windows, garages and vulnerable routes.

A good intruder alarm is not just a box on the wall. We look at how the property is entered, where weak points sit, whether pets are present, how the building is used day-to-day and who needs control from the app or keypad.
Alarm Planning

External sounders, PIR sensors, door contacts, keypads and smart alerts.

Planned for useful protection without false-alarm chaos.
