RaySense DAS is a security system that offers fiber optic monitoring capabilities. It can provide 100% perimeter coverage for long-range applications without sensor gaps. The cable itself acts as the sensor, which allows for the detection and location of intrusions based on real-time AI analysis based on an anomaly and signature database. Thus, it avoids false alarms better than traditional fiber optic systems.

The detection capability of RaySense is based on acoustics, which allows the cable to detect any intrusion without any physical movement of the fiber optic sensor cable. This feature makes it possible to bury the cable in any ground. The RaySense system does not require any power in the field, and its installation process minimizes the need for trenching and expensive installation methods.

The RBtec point intrusion detection system is the most cost-effective and high-performance solution for protecting long perimeters and other infrastructure.

Deploying the RaySense fiber-optic intrusion detection system provides a reliable perimeter security solution for areas up to 100 kilometers or 62 miles, using a single fiber-optic cable. The system can detect and locate intrusions within a 6-meter or 20-foot along the entire perimeter. The RaySense can be connected to additional RaySense controllers in a daisy-chain configuration to extend the reach of the system infinitely.

Installation Layout

Utilizing fiber-optic cable, the system is the most economically competitive technology currently available for long distances.  Requiring only a single alarm processing unit (APU) to cover up to 100 km/62 Miles, combined with a rugged fiber-optic sensing cable, results in the most cost-effective solution for large perimeters with only a few components.

Advantages of RaySense DAS AI Fiber Optic Sensor System

Performance and Features

• False Alarm Rejection: Raysense’s AI analytics considerably reduce false positives, distinguishing genuine threats with high precision. In contrast, other DAS systems have dated technology with a fixed calibration that does not allow them to adapt to changes in seasons and fence conditions and requires periodic recalibration.
• Calibration and Sensitivity Adjustment: RaySense allows easy calibration and user-driven sensitivity adjustments post-installation. Others lack this flexibility.
• Troubleshooting and Maintenance: Raysense’s AI streamlines the troubleshooting process, offering smart diagnostics and solutions. In contrast, other systems may require more specialized knowledge for maintenance and troubleshooting.

Applications:

• Borders
• Airports and Sea Ports
• Energy and Utilities
• Petroleum and Chemical
• Military and Government

Additional Advantages of RBtec RaySense

1. Real 2ch Self-Healing Ring: This feature indicates system reliability and resilience, with the capability to maintain consistent operation even when the fiber is cut automatically.
2. 3m Pin Point Detection offers precise localization of disturbances, which is essential for rapid response and detailed monitoring. This feature highlights its superiority in spatial resolution over others.
3. Scalability: The RaySense system is ideal for extensive perimeters over 3 miles or 5 kilometers, showcasing its suitability for large-scale security applications. Multiple workstations can monitor one RaySense, and one workstation can monitor multiple RaySenses.
4. Offline AI Operation: This operation operates independently without an internet or cloud connection, providing enhanced security for sensitive data and reducing dependency on cloud-based infrastructure.
5. Cost-Efficiency: No monthly fees or hidden costs are associated with the Raysense system, presenting a straightforward financial advantage for long-term operational budgeting.
6. Infrastructure Simplicity: Eliminating the need for field power or electronics simplifies the installation and maintenance, which is especially advantageous for deployments in remote or challenging environments.

What is DAS?

A DAS is an advanced variant of an Optical Time Domain Reflectometer (OTDR) that monitors the coherent Rayleigh backscatter noise signature in a fiber optic cable as pulsed light is sent into the fiber. The coherent Rayleigh noise generates a fine structure in the backscatter signature of the fiber cable. The DAS focuses on the Raleigh component to increase its prominence in the backscatter trace.

DAS is optimized to measure small changes in the coherent Rayleigh noise structure that occurs from pulse to pulse. Since the coherent Rayleigh noise structure is generated interferometrically within the fiber by the relative locations and strengths of local scattering centers intrinsic to the structure of the glass, very small physical (acoustic or vibration) disturbances at a point in the fiber can make detectable changes in the interferometric signal.
