Alarm Systems & Software

Alarm Systems & Software Overview

Alarm systems provide a vital line of defence for any site, acting as both a deterrent and an early warning system for intrusion.

Well-designed systems will result in intruders moving on before even attempting to break in. However, for persistent criminals, a good alarm system will activate immediately when a fenceline or facility is breached, generating a quick response to minimise losses.
