Introduction

The Intrusion Detection System is a cutting-edge solution utilizing Distributed Acoustic Sensing (DAS) technology to enhance security by detecting unauthorized access, whether from animals, humans, or other potential threats, near critical areas such a railway tracks or secured perimeters.

Technology Overview

The system employs laser pulses along a fiber optic cable to detect and analyse changes in acoustic signatures, enabling precise identification and localization of potential intrusions.

Working Principle

The system continuously monitors designated areas, comparing real-time disturbances againts references signatures. It triggers alarms for detected intrusions, be it animals, humans or other entities, allowing for immediate response.

Types of Intrusion Detection Systems

1. RAILWAYS

• Optical Fibre Cut Loss: Real-time alerts for cable cuts, defects, and stress.
• Intrusion Detection: Detects digging and animal movement on or near tracks.
• Tunnel Monitoring: Identifies seismic activity and tampering in tunnels.

2. AIRPORTS

• Perimeter Security: Monitors fence breaches and nearby disturbances.
• Runway Incursion Detection: Detects unauthorized access on runways/taxiways.
• Infrastructure Monitoring: Tracks health of critical assets like towers and runways.

3. DEFENCE

• Tunnel Detection: Profiles digging/blasting activities underground.
• Military Perimeter Security: Real-time detection of unauthorized movement.
• Border Surveillance: Alerts on crossings, classifies human/vehicle activity.

4. OIL & GAS

• Fracking Monitoring: Supports seismic and pressure mapping.
• Pipeline Monitoring: Detects leakage, pressure loss, and digging threats.
• Pump Monitoring: Identifies motor faults via vibration analysis

5. POWER & TELECOM

• Grid Monitoring: Detects intrusions near substations and power lines.
• Telecom Protection: Monitors cable tampering and suspicious vibrations.
• Data Center Security: Flags underground access near sensitive routes.

6. MARITIME & COASTAL

• Cable Protection: Monitors subsea cables for tampering or anchor strikes.
• Port Security: Detects vessel movement and underwater intrusion.
• Wind Farm Safety: Monitors structural integrity and underwater threats.

7. METRO & ROADWAY

• Track Health: Detects cracks, wear, and misalignment.
• Intrusion Detection: Alerts on tunnel tampering or sabotage.
• Traffic Analytics: Classifies vehicle movement for smart traffic control.

8. ENVIRONMENT & WILDLIFE

• Poaching Prevention: Distinguishes human/vehicle presence from wildlife to support patrol efforts.
