What’s the difference between monitored and unmonitored intruder alarms for shops in London?
Monitored vs Unmonitored Intruder Alarms for London Shops
For retail shops in London, choosing between a monitored and unmonitored intruder alarm can significantly impact the level of protection your business receives. Unmonitored systems sound a local alarm if triggered, but rely on someone nearby to respond. Monitored systems, by contrast, send signals to a remote alarm receiving centre (ARC), which can contact police, keyholders, or a security provider immediately.
Monitored intruder alarms offer a more reliable and rapid response to break-ins, especially during closed hours or holidays when no staff are on-site. These systems often include dual-path communication, 24/7 support, and optional police response (with URN registration). Unmonitored alarms may be cheaper initially but offer less assurance of intervention.
