General Details for Metro Perimeter Security

Metro perimeter security provides a robust, multi-layered defense to safeguard stations, depots, tracks, and critical metro infrastructure from unauthorized access, vandalism, and intrusion. It combines high-security fencing or boundary walls with anti-climb and anti-dig measures, integrated with fiber-optic–based Perimeter Intrusion Detection Systems (PIDS) that deliver real-time, high-accuracy detection of cutting, climbing, tampering, and ground disturbance with minimal false alarms. The solution is further strengthened by intelligent surveillance, controlled access points, and centralized command-and-control systems, ensuring continuous situational awareness, rapid response, passenger safety, and compliance with national urban transport security standards.

Securing the perimeter is the first and most critical layer of protection for metro rail systems, stations, depots, and rail infrastructure facilities. The FOL-101 Fence and Buried Perimeter Intrusion Detection System provides continuous, real-time monitoring of both perimeter fence lines and underground boundaries using advanced fiber-optic sensing technology. The system is specifically designed to detect unauthorized access, trespassing, vandalism, theft, and sabotage, including fence climbing, cutting, pulling, lifting, and tampering, as well as digging and tunneling near metro corridors and depots — before a security breach occurs. With high detection accuracy and very low nuisance alarms, FOL-101 delivers reliable security for high-traffic and safety-critical metro environments.

How the Fence and Buried Perimeter Security Works?

A single-mode fiber-optic sensing cable is installed on the perimeter fence and/or buried underground along the metro station, depot, or track 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 across different zones
Faster response time and improved operational efficiency
Ideal for high-risk and restricted transit zones

Key Advantages for Metro Security

Early intrusion detection before perimeter breach
Extremely low nuisance alarms with 24×7 reliable security
No electrical power required on fence or buried perimeter
Immune to EMI, lightning, and harsh weather conditions
Suitable for long, linear, and complex metro perimeters
Centralized monitoring from a secure Metro Control & Operations Room

Securing Fences & Buried Perimeter for Metro

No Product Image

FR-201 is a point-locating Fiber Optic Intrusion Detection System designed to protect metro rail systems, stations, depots, yards, tunnels, and other critical urban rail infrastructure. Metro environments require layered, fail-safe perimeter protection to prevent unauthorized access, trespassing, vandalism, theft, sabotage, and unsafe intrusion near operational rail assets. The FR-201 provides continuous, real-time monitoring of both perimeter fence lines and buried perimeters using advanced fiber-optic sensing technology. The system is engineered to detect, classify, and precisely locate intrusion attempts such as fence climbing, cutting, pulling, ground disturbance, digging, or tunneling — before the perimeter is breached, enabling rapid and coordinated response by metro security and operations teams.

How the System Works?

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