General Details for Airports Perimeter Security

Securing the perimeter is the first and most critical layer of physical protection for airports, airfields, runways, and aviation infrastructure facilities. The FOL-101 Fence and Buried Perimeter Intrusion Detection System provide continuous, real-time monitoring of both perimeter fences and underground boundaries using advanced fiber-optic sensing technology. The system is specifically designed to prevent unauthorized access, trespassing, sabotage, vandalism, theft, and intrusion attempts in high-risk airport environments. It reliably detects fence climbing, cutting, pulling, lifting, and tampering, as well as digging or ground disturbance near the airport perimeter — before any security breach occurs. With high detection accuracy and extremely low nuisance alarms, the FOL-101 ensures reliable 24×7 protection for airports, supporting aviation safety, airside security, and regulatory compliance.

How the Fence and Buried Perimeter Security Works?

A fiber-optic sensing cable is installed on the perimeter fence and/or buried underground along the airport boundary. The perimeter is divided into Zone 1 to Zone 8, each covering up to 500 m range. Any physical disturbance on the fence or ground generates an instant alarm. The controller identifies the exact zone of intrusion, and alarms are transmitted to the central control room for immediate response.

Zone-Based Alarm Detection

• Exact intrusion location displayed zone-wise
• Multiple intrusions can be detected simultaneously in different zones
• Reduces response time and improves operational efficiency of airport security personnel
• Ideal for airports, runways, taxiways, and restricted airside zones

Key Advantages for Airport Security

• Early intrusion detection before perimeter breach
• No false alarms with 24×7 highly reliable security
• No electrical power required on the fence
• Immune to EMI, lightning, radiation, and extreme weather conditions
• Suitable for long, open, and complex airport perimeters
• Centralized monitoring from the airport security control room, ATC-linked security center, or remote monitoring facility

FR-201 is a point-locating Fiber Optic Intrusion Detection System designed to protect airports, airfields, runways, and critical aviation infrastructure. Airports require multi-layered, highly reliable perimeter security to prevent unauthorized access, trespassing, sabotage, vandalism, theft, and covert intrusion attempts such as digging or boundary breaches near airside and restricted zones. The FR-201 provides continuous, real-time monitoring of both perimeter fencing and buried boundaries using advanced fiber-optic sensing technology. The system is engineered to detect, classify, and precisely locate attempts to breach the secured perimeter — including fence attacks, ground disturbance, digging, or tunneling — well before a security breach occurs, enabling immediate and targeted response to protect passengers, aircraft, and airport operations.

How the System Works?

A single-mode fiber-optic sensing cable is installed on the perimeter fence and/or buried underground along the airport boundary. The same sensing cable can protect fence and buried zones simultaneously. Any disturbance creates a signal that is analyzed by the FR-201 controller. The system generates a pinpoint location alarm within a few meters, and the exact intrusion point is displayed on the monitoring system, allowing security teams to respond quickly and accurately to real threats.

Fence Intrusion Detection

• Climbing
• Cutting
• Pulling or lifting of the fence
• Fence tampering

Buried Perimeter Detection

• Digging
• Tunneling
• Ground disturbance near walls, foundations, or cable trenches
• Covert intrusion attempts

Pinpoint Location Alarms

• Intrusion location accuracy within a few meters
• Supports multiple simultaneous intrusion events

Integration

• Alarm data available via:
  • TCP/IP (XML, ASCII, Modbus)
  • Relay outputs
• Can automatically trigger PTZ cameras, hooters, and flood lights

Key Advantages for Airport Security

• Early detection before breach
• Alarms displayed on map with precise meter location and GPS coordinates
• Extremely low nuisance alarms with 24×7 reliable security using intelligent pattern recognition algorithms
• No electrical power required in the field
• Immune to EMI, lightning, and harsh weather conditions
• Cut-immune configuration — system remains operational even if cable is cut
• High reliability for mission-critical aviation and airport operations
• Centralized monitoring from the Airport Security Control Room, Operations Control Center, or remote monitoring facility
• Precise intrusion location can automatically trigger cameras
