Take Note IT


The Terra Sense is highly intelligent invisible fence utilising “DISTRIBUTED ACOUSTIC SENSING (DAS)” based technology, using a single strand of fibre optical (f/o) cable, can monitor a distance of up to 100 km. The buried cable can detect the presence of people or vehicles within 10m range depending on ground conditions (average 2m). The Terra Sense will localize the event along the cable to within 10m.

Unbreakable Security

Guarding Your Perimeter with Distributed Acoustic Sensing (DAS)

Traditional security measures can have blind spots. DAS technology offers a powerful solution, turning your existing fiber optic cables into an impenetrable security fence. Our DAS systems provide real-time detection and analysis of vibrations and acoustic disturbances, giving you an unparalleled advantage in protecting your property and assets.

Here’s how DAS keeps you ahead:


  • 24/7 Perimeter Intrusion Detection: DAS continuously monitors your perimeter for any unauthorized activity, from cutting fences to attempted break-ins.
  • Early Warning for Cable Theft: DAS detects even the slightest vibrations caused by tampering with underground or overhead cables, allowing for immediate intervention.
  • Long-Range Protection: A single fiber optic cable can secure vast perimeters, eliminating the need for multiple sensors and reducing security infrastructure costs.
  • All-Weather Reliability: DAS functions flawlessly in any weather condition, ensuring uninterrupted perimeter security.
  • Intelligent Threat Analysis: Advanced software analyses the detected disturbances, distinguishing between genuine threats and environmental noise, minimizing false alarms.


DAS offers a smarter, more effective security solution. Contact us today to learn how we can customize a DAS system to meet your specific security needs.

Deterring Threats Before They Happen

Long Range Acoustic Devices & Tactical Blinding Lights

Traditional security measures often react after a crime occurs. Our deterrent technologies take a proactive approach, discouraging trespassers and intruders before they reach your property.

Empower your security with:


  • Long Range Acoustic Devices (LRADs): These powerful devices emit high-pitched, directed sound waves that create discomfort, deterring potential intruders and animals without causing permanent harm.
  • Tactical Blinding Lights: These high-intensity lights temporarily disorient and confuse trespassers, providing valuable time for security personnel to respond.
  • Artificial Intelligent Deterrent Gun: Our security systems leverage a wired AI system with superior human presence detection. When triggered, an alarm instantly alerts our central Security Operations Center (SOC). There, highly trained operators assess the situation in real-time. They can mute the alarm for false positives. For confirmed intrusions, operators can fire non-lethal deterrents like pepper spray or rubber bullets.


Together, these technologies create a powerful deterrent zone, significantly reducing the risk of break-ins and vandalism.
