Distributed Sensing for Perimeter Security

Security Begins at the Boundary

Every critical facility—from industrial sites and energy plants to data centers and defense zones—has a perimeter.But fences and cameras alone cannot stop a determined threat.Real protection begins when you can understand what’s happening across every meter of your boundary—in real time, even when it can’t be seen. The DAS (Distributed Acoustic Sensing) based applications within the FOTAS portfolio take perimeter security beyond traditional systems by instantly detecting and locating the physical disturbances that occur along the fiber optic cable.

Global Reference Projects with FOTAS

FOTAS technologies have been successfully deployed in various perimeter security projects across the globe. From the Çamlıca TV Tower in Istanbul to the Tasiast gold mine in the Mauritanian desert, and from solar farms in Brazil to high-security prisons in Mexico, FOTAS systems have demonstrated reliable detection of threats under diverse conditions. These real-world applications highlight FOTAS’s adaptability, precision, and integration capability in both urban and remote environments.

Hearing What Eyes Can’t See

Distributed Acoustic Sensing (DAS) turns buried fiber optic cables into continuous detection lines.

It identifies:

• Approaching footsteps
• Vehicle movement and vibration
• Climbing or cutting of fences
• Digging or tunneling under perimeter lines

All analyzed and classified in real time.

DAS not only detects movement—it understands what it is and how critical it may be.

Precision in High-Noise Environments

False alarms near roads or populated areas waste time and drain resources.
FOTAS distinguishes between threats and harmless movement—differentiating a blowing bush from a real intrusion attempt.

This level of sensitivity ensures both fewer false positives and a faster, smarter response from security teams.

DTS: An Extra Layer Against Heat-Based Threats

Some perimeter zones include power lines, electrical boxes, and cable corridors.
Here, Distributed Temperature Sensing (DTS) takes over.

DTS detects thermal changes along fiber lines to identify:

• Early signs of fire
• Electrical faults or shorts
• Overheating at cable junctions

All before physical damage occurs.

Application Areas

• Power stations and substations
• Data centers and telecom hubs
• Airport and seaport perimeters
• Industrial zones and refineries
• Oil field and airfield fencing

Each of these zones faces a mix of physical threats and environmental noise.
FOTAS listens across the entire landscape—not just to intrusions, but to the context behind them.

It not only detects what’s happening—but knows where it’s coming from, how serious it is, and whether to trigger action.
This is not just security. It’s security with foresight.

With FOTAS, Security Starts at the Edge

• Real-time perimeter monitoring and event classification
• High-precision alarm system with low false alert rates
• Passive, embedded infrastructure: energy-free and undetectable
• Seamless integration with Closed-Circuit TV (CCTV), Building Management Systems (BMS), Supervisory Control and Data Acquisition (SCADA), and alarm centers
• Compatible with physical barrier systems, lighting control, zonal automation, and central security platforms
• Long-term protection with minimal maintenance

DAS and DTS are no longer optional extras in perimeter security—they are becoming essential.

These systems elevate traditional security by interpreting risk, not just reporting motion. For high-security infrastructure, FOTAS becomes an invisible but indispensable part of the perimeter. Boundaries are no longer just defended—they’re monitored, analyzed, and intelligently secured.
