Our Expertise
Distributed Acoustic Sensing (DAS) Expertise
We provide specialized expertise in Distributed Acoustic Sensing (DAS), delivering advanced fiber-optic monitoring solutions for real-time detection, analysis, and interpretation of acoustic signals along pipelines, wells, railways, and critical infrastructure. Our services include system design, deployment support, data processing, signal interpretation, and performance optimization to enhance asset integrity, operational efficiency, and risk mitigation.
DAS Perimeter Intrusion and Detection: Early Warning
Real-time perimeter security using Distributed Acoustic Sensing (DAS) to detect and classify intrusion events such as digging, cutting, footsteps, or vehicle movement. The system provides early warning alerts to protect critical infrastructure and high-value assets.
DAS Leak Detection
Advanced fiber-optic acoustic monitoring to identify and locate leaks in pipelines and fluid transport systems with high precision. Enables rapid response, minimizes environmental impact, and reduces operational losses.
DAS Cable Monitoring
Continuous integrity monitoring of fiber-optic and power cables to detect third-party interference, physical damage, or abnormal activity along the route, ensuring network reliability and asset protection.
DAS Railway Monitoring
Real-time railway infrastructure monitoring to detect train movement, track anomalies, trespassing, and potential safety risks. Enhances operational efficiency, predictive maintenance, and passenger safety.
Surveillance and Monitoring Systems
Integrated surveillance solutions including CCTV, sensors, access control, and centralized monitoring platforms to provide comprehensive situational awareness and infrastructure protection.

Target Industries
RNSA delivers advanced fibre-optic sensing solutions powered by SINTELA’s Distributed Acoustic Sensing (DAS) technology. Our systems transform standard fibre-optic cables into intelligent, real-time monitoring networks capable of detecting, locating and classifying events across vast distances with exceptional accuracy.
Border & Perimeter Monitoring
Protecting national borders and high-security perimeters requires reliable, long-range detection solutions. Our fibre-optic sensing systems provide continuous monitoring along fences, buried cables, and remote boundary lines.
Using Distributed Acoustic Sensing (DAS), the fibre cable becomes a virtual sensor array capable of detecting:
-
Footsteps and human movement
-
Vehicle activity
-
Digging or tunnelling attempts
-
Fence cutting or tampering
-
Suspicious ground disturbances
Events are detected and precisely located in real time, enabling rapid response while minimising false alarms.
Ideal for:
National borders, military bases, airports, correctional facilities, industrial sites, and critical infrastructure installations.
Traffic Monitoring – Road Networks & Smart Transport
RNSA provides intelligent traffic monitoring solutions using fibre-optic sensing technology deployed along roadways and highways.
Unlike traditional camera or loop-based systems, DAS technology detects vehicle vibrations and acoustic signatures directly through existing fibre infrastructure. This enables:
-
Real-time vehicle detection
-
Traffic flow analysis
-
Congestion monitoring
-
Incident and accident detection
-
Vehicle classification and speed estimation
Our solution supports smart city initiatives and modern traffic management systems by delivering continuous, scalable monitoring over long distances.
Ideal for:
Transport authorities, toll operators, municipalities, and smart city infrastructure projects.
Power Transmission Line Monitoring
Power transmission networks span vast, often remote areas that are difficult to monitor continuously. RNSA’s fibre-optic sensing solutions provide real-time visibility across transmission lines and associated assets.
The system can detect:
-
Structural stress or cable vibration anomalies
-
Environmental impacts (wind, storms, seismic activity)
-
Tampering or sabotage attempts
-
Maintenance-related issues before failure occurs
By identifying potential risks early, utilities can reduce downtime, improve grid reliability, and enhance infrastructure security.
Ideal for:
Electricity utilities, energy providers, and national grid operators.
