Intruder Alarms

A sensory warning and
timeless deterrent.

An intruder alarm is a vital part of any security system and a proven method of deterrence. It will alert you instantly to any breach of your property and cause panic in the mind of a would-be intruder. Coupled with a mobile phone app-based system, it will alert you and other keyholders of a breach wherever you are in the world and can be linked to an ARC (alarm receiving centre) allowing authorities to respond quickly, significantly reducing the risk to your property.
