Threat Model

Escapes, contraband smuggling, external attacks. Gives correctional operators faster zone pinpointing and cleaner alarm routing for high-consequence incidents.

Fiber Optic Sensing for Perimeter Security for Corrections

Correctional and juvenile facilities require zero-tolerance perimeter security to prevent escapes. Our systems detect climbing attempts, ladder placement, and wall impacts, ensuring perimeter integrity. The system is robust against tampering and provides precise location data to direct response teams to the exact sector of the breach. FortSense 4 adds zone-level alarms, low false alarm filtering, and relay or IP outputs for CCTV, VMS, PSIM, and SOC workflows.

Security Challenges

Main Threats to Perimeter Security for Corrections

1

High-consequence perimeter breaches

2

Contraband delivery attempts near the perimeter

3

Mixed barriers and blind spots (fence + wall + concertina)

4

Nuisance alarms that slow response

5

Need for audit-ready incident history

Installation

Typical Deployment

On inner and outer perimeter fences and walls. Controllers can segment fence lines, gates, walls, and mixed perimeter runs into response-ready zones.

Fence Perimeter Sensing

Chain-link / welded mesh applications.

Concertina / Razor Wire Sensing

Where applicable for barrier protection.

Wall / Solid Barrier Sensing

Zoning is physically defined during design to match perimeter layout.

How It Works

How FortSense Detects Intrusions

Fiber optic cable transforms into a continuous perimeter sensor, detecting threats in real-time

1

Fiber Installed

Passive fiber optic cable is mounted along your fence, wall, or buried underground

2

Vibration Detected

Any physical contact with the perimeter creates vibration patterns in the fiber

3

AI/DSP Verification

Advanced algorithms analyze the signal to distinguish real threats from wind, animals, or environmental noise

4

Alarm if Intrusion

Only confirmed intrusion attempts trigger zone-based alarms for security response

Real-World Example

At a perimeter security for corrections facility, when someone attempts to cut the perimeter fence, the fiber optic cable detects the vibration pattern instantly. The system identifies the exact zone under attack and triggers an alarm within seconds, allowing security to respond before the breach occurs.

Detection Events

What We Detect

01
Fence cutting attempts
02
Climbing and lifting attempts
03
Wall attack / wall breaking events
04
Barrier tampering and impact events
05
Razor wire manipulation
06
Escape tunnel digging
07
Contraband delivery attempts
08
Coordinated perimeter testing
09
Tool concealment and preparation
10
Vehicle ramming escape attempts

FortSense 4 interprets vibration patterns on the protected barrier and triggers alarms by zone to support fast response.

Technology Comparison

Fiber Optic Detection vs. Camera-Only Systems

Understanding the critical differences in perimeter security technology.

Blind Spots

Fiber Optic

100% perimeter coverage - follows every inch of fence

CCTV/Video

Cameras miss corners, obstructions, and areas between fields of view

Weather Immunity

Fiber Optic

Rain, fog, dust, darkness - no impact on detection

CCTV/Video

Reduced visibility in bad weather, night requires IR/lighting

Pre-Intrusion Detection

Fiber Optic

Detects cutting, climbing BEFORE breach occurs

CCTV/Video

Only sees intruder AFTER they're on property

False Alarm Reduction

Fiber Optic

Advanced DSP filters wind, animals - learns fence signature

CCTV/Video

Triggers on shadows, leaves, animals, lighting changes

Best Practice: Use Both Together

Fiber optic for detection - Alerts you the moment someone touches your fence, even in complete darkness or bad weather.

Cameras for verification - Automatically point to the alarmed zone to visually confirm and record the threat.

💡 Pro tip: FortSense integrates with major VMS platforms like Digifort and ISS to trigger camera presets automatically when an alarm occurs.

Key Advantages

Zero-tolerance detection for escapes.
Precise location of intrusion attempts.
Immune to environmental factors.
Zone-level alarms accelerate camera verification and operator response.
Connectivity

Integrations & Rapid Response

FortSense 4 integrates seamlessly with your existing security infrastructure via dry contacts, TCP/IP, and major VMS platforms to ensure a coordinated and rapid response to any intrusion event.

  • Camera call-up / presets (where supported by your VMS)
  • Alarm panel and control room workflows (platform-dependent)
  • Incident handling procedures (acknowledge, dispatch, verify)
  • Correlation across zones for prioritization (platform-dependent)

Support

Frequently Asked Questions
