What the System Is

Intruder alarm systems are designed to detect unauthorised access and alert you immediately. Available as both wired and wireless solutions, these systems utilise motion sensors, door contacts, control panels, and external sounders to provide full property protection. Depending on your security needs, you can choose a traditional “bells-only” system to deter intruders locally, or opt for a fully monitored setup that alerts you via a smart device or connects directly to our ARC (Alarm Receiving Centre) for ultimate peace of mind.
