Fiber perimeter intrusion detection systems

https://www.raycomsecurity.com/fiber-fence.html

Fiber optic perimeter intrusion detection systems (FOPIDS) employ a highly sensitive optical fiber cable to sense disturbances such as vibrations, climbing, cutting, or digging along perimeter fences, underground lines, or other structures. These systems deliver dependable, real-time, and precise intrusion alerts, remain unaffected by electromagnetic interference, and maintain a low false-alarm rate, making them an excellent choice for protecting critical infrastructure and expansive sites.

How FOPIDS Operate

Sensor Cable: A single-mode optical fiber cable is deployed along the perimeter, typically attached to fences or buried beneath the ground.

Vibration Detection: The cable reacts to mechanical disturbances such as vibrations caused by climbing, cutting, or digging.

Signal Processing: A connected processor detects variations in the light traveling through the fiber.

Intrusion Alert: These light changes trigger an alarm, and the system can usually pinpoint the intrusion’s location within a few meters.

Key Advantages

High Sensitivity & Accuracy: Captures even minor vibrations from climbing, cutting, or digging, while providing precise location details.

EMI Immunity: Because it uses light instead of electricity, the system is unaffected by electromagnetic or lightning interference, making it reliable in harsh conditions.

Low False-Alarm Rate: Advanced processing technology filters out noise so security teams can focus on real threats.

Real-Time Detection: Delivers instant alerts for a rapid response to intrusion attempts.

Flexible Installation: Suitable for fences, underground deployment, or wall-top setups.

Cost-Effective: Requires minimal maintenance and components, and can operate without on-site power sources.

Common Applications

Border Security: Monitoring and safeguarding extensive, remote borders for civilian and military use.

Critical Infrastructure: Providing protection for essential facilities such as power plants and data centers.

Pipelines and Conduits: Detecting digging, intrusions, or possible damage to underground pipelines.

High-Security Areas: Securing sensitive buildings, compounds, and other restricted zones.
