Our Sensing Technologies

A single fiber optic cable becomes a powerful, multi-parameter sensing array, providing unparalleled insight into the health and security of your assets over vast distances.

DTS - Distributed Temperature Sensing

Measures temperature continuously along the entire length of the fiber, pinpointing hotspots with precision.

  • Power Cable & Cable Tray Monitoring
  • Pipeline Leak Detection (Thermal Anomaly)
  • Downhole Well Monitoring

DVS - Distributed Vibration Sensing

Detects vibrations caused by physical disturbances, classifying events like walking, digging, or climbing.

  • Perimeter Security & Intrusion Detection
  • Third-Party Intrusion (TPI) on Pipelines
  • Railway & Tunnel Monitoring

DAS - Distributed Acoustic Sensing

Captures the full acoustic field along the fiber, allowing for detailed event analysis and classification.

  • Pipeline Leak Detection (Acoustic Signature)
  • High-Fidelity Security Monitoring
  • Seismic & Geotechnical Surveys

Integrated Application Solutions

We don't just sell hardware; we deliver a complete solution. Our systems are engineered and fine-tuned in our factory for the unique challenges of your industry.

Perimeter Security

Transform any fence line or buried perimeter into a 24/7 intelligent intrusion detection system. A single fiber cable, often already present, provides covert monitoring immune to weather, EMI, and tampering.

  • Precise Event Location: Pinpoint intrusions to within meters, guiding an immediate and effective response.
  • Intelligent Classification: DVS/DAS algorithms distinguish between footsteps, vehicle movement, digging, and fence climbing, reducing false alarms.

Oil & Gas Pipeline Monitoring

Ensure the integrity and safety of hundreds of kilometers of pipeline from a single control room. Our systems provide early warning for leaks and third-party intrusion, preventing environmental disasters and costly repairs.

  • Leak Detection: DTS detects temperature changes from escaping gas/liquid, while DAS identifies the unique acoustic signature of a leak.
  • Third-Party Intrusion (TPI): DVS/DAS detects and classifies the acoustic and vibrational signatures of digging equipment near the pipeline, preventing accidental strikes.

Power Cable & Asset Monitoring

Optimize the performance and ensure the safety of critical power infrastructure. DTS allows for Dynamic Cable Rating (DCR), while DVS/DAS can detect faults and third-party interference.

  • Dynamic Cable Rating: Safely increase power transmission capacity by monitoring the cable's true temperature in real-time.
  • Fault Location: Instantly locate cable faults, short circuits, or damage to cable bridge tray infrastructure, drastically reducing outage times.

The FJINNO Command Platform

Hardware is only half the story. Our powerful, intuitive software platform is the brain of the operation. It fuses data from DTS, DVS, and DAS systems into a single, actionable view.

  • GIS-based mapping for intuitive visualization.
  • AI-powered event classification to minimize false alarms.
  • Customizable alarm zones and notification settings.
  • Seamless integration with third-party SCADA and VMS systems.
