Fence & Warehouse Protection
Flexiguard™
A microphonic sensor cable that turns any fence line, wall or warehouse into an intelligent intrusion detection system.
Overview
Flexiguard™ is a microphonic perimeter intrusion detection system (PIDS) built around the FS30X series analyzer and a highly sensitive vibration sensor cable, processed in-house to make it the most sensitive microphonic cable available. Attached to the fabric of a fence, the cable detects an intruder cutting, climbing or lifting the fence and raises the alarm before the intrusion.
The same cable also protects buildings. Mounted on the walls of a warehouse or store, Flexiguard™ picks up the vibrations of a forced-entry attempt, extending detection from the fence line to the building itself. Automatic Environmental Control (A.E.C.) is built into the analyzer to prevent false alarms from wind, rain or barbed-wire movement.
Through customer training, advanced techniques can be learned and used to filter out unwanted, unavoidable sources of vibration without risking PIDS integrity.
With extremely low power consumption, Flexiguard™ is ideal for solar-powered installation, and a wireless alarm communication option removes the need for cabling back to the gatehouse. Trusted on some of the world’s most critical sites, including 14.2 km of perimeter around archaeological sites at the Pyramids of Egypt.

How It Works
Detect. Deter. Alert. Record.
Detect
The microphonic cable converts fence or wall vibration from an intrusion attempt into an analysable signal.
Analyse
A.E.C. Automatic Environmental Control distinguishes genuine attacks from wind, rain and environmental noise.
Alert
A validated alarm is raised against the precise detection zone along the perimeter or building.
Record
Alarms are passed to Multisys® or any dry-contact system for operator assessment and logging.

Flexiguard™ questions, answered.
What is Flexiguard?
Flexiguard is a microphonic perimeter intrusion detection system built around the FS30X series analyser and a highly sensitive vibration sensor cable. Attached to the fabric of a fence, the cable detects an intruder cutting, climbing or lifting the fence and raises the alarm before the intrusion. Flexiguard is NPSA assured.
Can Flexiguard protect a building as well as a fence?
Yes. Mounted on the walls of a warehouse or store, the same sensor cable picks up the vibrations of a forced-entry attempt, extending detection from the fence line to the building itself.
How does Flexiguard avoid false alarms from wind and rain?
Automatic Environmental Control (A.E.C.) is built into the analyser to distinguish genuine attacks from wind, rain and barbed-wire movement. Through customer training, advanced techniques can also be applied to filter out unavoidable sources of vibration without compromising detection.
How long can a Flexiguard zone be, and what power does it need?
Each FS30X analyser supports two zones of up to 300 metres. The analyser runs from 12 to 21 V DC and draws 0.5 watts on average, which makes it ideal for solar-powered sites, and a wireless alarm communication option removes the need for cabling back to the gatehouse.
Is there a Flexiguard version for hazardous areas?
Yes. An intrinsically safe Flexiguard system is available for hazardous areas such as oil and gas sites, delivered with APS certified partner companies.
Where has Flexiguard been deployed?
Flexiguard is trusted on some of the most critical sites in the world, including 14.2 km of perimeter around the archaeological sites at the Pyramids of Egypt, a fully solar-powered UK solar farm boundary and a DPD parcel depot, as well as airports, utilities, ports and military estates.
