Why FOTAS?

Modern critical infrastructures face threats that appear suddenly and escalate fast. An unauthorized excavation near a pipeline, a fence being cut, someone tampering with a fiber cable, a strange vibration along a railway, or unexpected movement on a border line… If these signs are missed or detected too late, the consequences can be serious.

Traditional point sensors simply can’t keep up. They watch only the limited spots where they are installed, leave gaps in between, trigger late, and demand constant maintenance.

That’s why the real question is no longer “Is a sensor enough?”
The real question is:

“Why choose DAS — and why choose FOTAS?”

In pipeline security, railways, borders, and long energy corridors, DAS is the only technology that can deliver continuous, gap-free acoustic monitoring across 50 km with a single fiber. Today, one of the most advanced and reliable implementations of this capability is the FOTAS platform

The Power of DAS:

Continuous Acoustic Awareness Across 50 km

FOTAS transforms a standard fiber optic cable into a continuous “awareness line” stretching up to 50 kilometers. Instead of watching isolated points, you gain visibility across the entire path.

This means:

• Wherever the cable goes, your security extends with it
• Blind spots disappear
• Even subtle vibrations become noticeable
• Virtual zones can be created to match your facility’s layout

In short, the system doesn’t just send alarms — it shows you what’s happening along the whole route, in real time.

What Makes DAS Strong — and What Makes FOTAS Different

Below are not just technical advantages, but real operational benefits for the people who rely on the system every day.

1. Blind Spots Are Now a Thing of the Past: Clear Visibility for 50 km

Point sensors see only their immediate surroundings.
FOTAS listens along the entire fiber route.

Whether it’s a border, a pipeline, a railway or a vast industrial corridor, once FOTAS is in place, no part of your infrastructure is left in the dark.

2. Events Are Caught Before They Grow: Real-Time Micro Detection

FOTAS picks up signals that many systems miss:

• light excavation noise
• a fence wire being pulled or cut
• small impacts on the ground
• footsteps or movement
• a vehicle approaching
• even the slightest touch on the fiber itself

This means incidents are detected before they fully develop.
Your security team reacts not after the event occurs, but while it is just beginning to form.
In other words, the system doesn’t wait for consequences — it identifies the earliest signs of activity and enables proactive response.

3. AI-Supported Interpretation: Say Goodbye to Unnecessary Alarms

FOTAS doesn’t just “hear” an acoustic signal — it understands it.

It distinguishes between:

• wind shaking the fence vs. an actual cutting attempt
• an animal passing vs. a person approaching
• routine vibration vs. a digging machine
• harmless noise vs. a real threat

Your operators don’t waste time chasing false alarms; the system filters the noise and sends you only what truly matters.

4. No Field Power, No Field Electronics: Simpler, Safer, More Reliable

FOTAS operates entirely on passive fiber. That means:

• no powered equipment along the route
• no weather-related failures
• no electrical risk
• minimal maintenance

A single central unit can monitor 50 km, making the system both operationally simple and economically efficient.

5. SCADA, CCTV, BMS… Everything Works Together: Control Stays With You

Integrating FOTAS into your existing ecosystem is straightforward.
With support for Modbus, TCP/IP, REST API, and SNMP, you can connect FOTAS to:

• your SCADA screens

• your CCTV and video analytics

• your building management system

• your command center dashboards

All information flows into one place, giving you full situational awareness.

6. Built to Withstand Harsh Conditions

Fiber optics naturally resist many environmental challenges:

• electromagnetic interference

• dust, moisture, mud

• extreme temperatures

• corrosive or chemical atmospheres

• explosive environments

That’s why FOTAS is ideal for pipelines, refineries, energy sites, military facilities, border zones, railways and remote locations where traditional sensors struggle.

7. Long Service Life With Very Low Energy Use

Since there are no powered devices in the field, energy consumption stays low and maintenance remains predictable. Over the long term, this leads to significantly lower operational costs and a highly sustainable investment.

Why FOTAS?

Because Security Is More Than Just Sensors**

It’s easy to explain DAS as a concept.
It’s much harder to build a DAS system that performs reliably across 50 km in real-world, harsh conditions.

FOTAS does exactly that.

With broader coverage, intelligent interpretation, low false alarms, long service life, seamless integration and globally proven performance, FOTAS turns DAS into a truly dependable security solution.

So the question becomes:
“If I need DAS, why should I choose FOTAS?”

The answer is clear:
FOTAS doesn’t just detect activity — it understands it, interprets it, and alerts you when it matters.
