Perimeter Intrusion Detection Systems
Perimeter Intrusion Detection Systems
Perimeter Intrusion Detection Systems (PIDS), including the advanced IRONCLAD and MICALERT product lines, deliver powerful, always-on protection for the outer edges of your property. Designed to sense and signal any unauthorised activity along fences, walls, or gates, these systems give security teams the critical early warning they need before a potential intruder can breach your space.
A fence alarm system allows you to receive an early warning that someone is trespassing. You need active perimeter security sensors to detect and stop intruders at your fence line.
Also available from First Fence is the RapiDetect™ PIDS Module, a versatile, solar-powered security solution that monitors and protects large outdoor areas.
How IRONCLAD and MICALERT PIDS Work
The core of the system is the microphonic sensor cable, which is installed directly onto the fence or barrier. This cable uses advanced technology to sense vibrations, cuts, climbs, or other disturbances characteristic of intrusion attempts. The system differentiates these specific intrusion signatures from harmless environmental noise (like wind or rain) to minimise false alarms.
A single run of the sensor cable placed along the middle of the fence can detect intrusion attempts across the entire fence height, up to 10 feet (3 meters). Each processor/analyser can handle multiple zones and provides individual alarm outputs for each one. The system works with any existing alarm setup and can be added to both new and older installations.
IRONCLAD: Features a cable protected by a stainless-steel braid, specifically optimised for wire fences, mesh, razor wire, and concertina coils.
MICALERT: Designed for a wider variety of perimeters, providing enterprise-grade analysis for rigid fences such as palisade and ornamental iron. MICALERT has a black UV-rated coating that is thinner and more discreet.
IRONCLAD & MICALERT Kits
These complete kits are available as Single Zone (one continuous detection area) and Dual Zone (two separate, independently monitored detection areas).
Single Zone Kits (75m, 150m, 300m): Each kit includes a roll of sensor cable in the specified length, two end-of-line termination boards (pre-installed), a local processor unit, and a weatherproof enclosure.
Dual Zone Kits (2x75m, 2x150m, 2x300m, 2x500m): These kits provide expanded coverage (up to 1km total) using two rolls of sensor cable with pre-installed termination boards, a dual-zone processor unit, and a weatherproof enclosure.
Sensor Cable & Spare Parts
Sensor Cable Rolls: Available in 75m, 150m, and 300m lengths for custom installations, repairs, or extensions.
End-of-Line Termination Unit (RB-MCTR): Required to correctly terminate the sensor cable and ensure signal integrity.
Connection Box (RB-MCTXT): Used for professional splicing or connecting cable segments.
Stainless-Steel Ties (RB-TIES610): For durable, UV-resistant, and secure attachment of the cable to the fence.
Gate Security
Specialised kits and components ensure protection remains continuous across access points:
Sliding Gate IRONCLAD Kit: Includes a reel of non-sensitive cord that spools as the gate moves, ensuring the processor does not register gate operation as an intrusion.
Single & Double Swing Gate Kits: Comprising the necessary components to span gate openings without using active sensor cable on the moving parts, effectively reducing false alarms.
Gate Plug Connector: Allows for the seamless connection of sensor cable to non-sensitive cable for underground routing.
About RapiDetect™
If you have a perimeter that changes every few weeks (like a moving construction site) or a high-security event that only lasts 48 hours, RapiDetect™ provides enterprise-level vibration sensing without the labour costs of a permanent install. It fills the gap between no security and expensive permanent infrastructure.
RapiDetect™ is an innovative detection system, designed to pick up, respond and deter any intruders who might be attempting to gain access to a site. It is solar-powered with motion detectors and cameras for comprehensive 360° detection. It effectively filters out false triggers and is easy to install without requiring a large team.
This is a mobile, plug and play module designed for instant deployment.
