General Details for Jails Perimeter Security

Jail perimeter security delivers a high-assurance, multi-layered protection system designed to prevent escapes, contraband smuggling, and unauthorized access. It integrates high-security walls or anti-climb fencing with anti-dig measures and fiber-optic–based Perimeter Intrusion Detection Systems (PIDS) that provide precise, real-time detection of cutting, climbing, tampering, and tunneling with extremely low false alarms. Combined with intelligent surveillance, controlled access points, and centralized command-and-control monitoring, the solution ensures continuous visibility, rapid response, and strict compliance with correctional security standards.

FOL-101

Securing Fences & Buried Perimeter for Jails

Securing the perimeter is the first and most critical layer of protection for jails and correctional facilities.

The FOL-101 Fence and Buried Perimeter Intrusion Detection System provide continuous, real-time monitoring of both fence lines and underground perimeters using advanced fiber-optic sensing technology.

The system is specifically designed to detect escape attempts and internal and external intrusions, including fence climbing, cutting, pulling, lifting, tampering, as well as digging and tunneling near the perimeter—before a breach occurs. With high detection accuracy and very low nuisance alarms, FOL-101 delivers reliable security for high-risk prison environments.

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 jail 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. 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 escape-prone and high-risk areas

Key Advantages for Jail Security

Early intrusion detection before perimeter breach
Extremely low nuisance alarms with 24×7 reliable security
No electrical power on fence or buried perimeter
Immune to EMI, lightning, and harsh weather conditions
Centralized monitoring from a secure control room

FR-201

Securing Fence and Buried Perimeter for Jails

FR-201 is a point-locating Fiber Optic Intrusion Detection System designed to protect jails and correctional facilities.

Jail sites require layered, fail-safe perimeter protection to prevent unauthorized access, sabotage, infiltration, tunneling, and coordinated internal and external intrusion attempts.

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, digging, or tunneling—before the perimeter is breached, enabling rapid and decisive security response.

How the System Works?

A fiber-optic sensing cable (single-mode) is installed on the perimeter fence and/or buried underground along the jail’s 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 forces to respond quickly and accurately to real threats.
