About
Advanced Perimeter Systems, originally named Armbell, was established in 1982 by Mr William H Campbell to design, develop & manufacture Perimeter Intrusion Detection Systems (PIDS).
Our systems were specifically designed for Commercial, Industrial, and Military use so are most commonly found in Prisons, Ministry of Defence sites, as well as protecting other critical infrastructure worldwide.
Based in Stirling, Central Scotland, UK our dedicated team possess a wealth of experience in all aspects of security system design and manufacture. Our product range is designed with high security in mind from the invisible Microguard, through to our world leader Flexiguard acoustic sensor monitoring system, to our ultimate deterrent Electro-Fence.
Our perimeter security technology is designed in the UK and as an ISO 9001 accredited manufacturer APS controls all aspects of manufacture.
