RaySense Fiber Optic Sensing Principle of Detection

Perimeter Intrusion Detection Systems are systems used in an external environment to detect the presence of an intruder attempting to breach a perimeter. With one of the market’s most innovative fiber optic monitoring capabilities, the RaySense provides 100% perimeter coverage for long-range applications without gaps between sensors. The fiber optic cable is the sensor.

The RaySense system is a powerful vibration acoustic sensor that uses a typical single-mode fiber optic cable. RBtec employs distributed acoustic sensing (DAS) technology and distributed vibration sensing (DVS) technology for different applications to monitor fiber optics. The fiber optic cable is highly sensitive to pressure, acoustics, and motion, which allows it to detect vibrations transmitted through the fence, soil, or the surface. The RaySense system can monitor the vibration signals along the length of the fiber optic cable, locate an intrusion event, and classify the specific signatures based on the detection algorithm.

The deployment of a RaySense fiber-optic intrusion detection system using a single fiber-optic cable is an excellent choice for ensuring reliable perimeter security over a distance of 5 to 100 km/3 to 62 miles. The system can detect and locate any intrusion within a 3-20m/10-60ft range across the entire perimeter. Additionally, the system can provide unlimited coverage by connecting with additional network controllers.

The Alarm Process Unit (APU) of the RaySense System is responsible for monitoring the optical signal. It uses advanced 2-layer AI algorithms to differentiate between breach, cut climb, walk, vehicle, and non-threatening nuisances. The RaySense System detects these activities by comparing them with a database of known vibration frequencies, making it easy to calibrate. Additionally, the system’s performance remains consistent over time, requiring minimal or no maintenance for the APU.

The RaySense is sold in two configurations, single channel or two channels. The RBtec PinPoint Intrusion Detection System is the most cost-effective, high-performance solution for protecting long perimeters and other infrastructure.

Why AI Matters?

The RBtec RaySense system employs Deep Learning (DL) algorithms, acting like a digital brain to learn from over 150,000 data records. It stands out because:

1. Predicting the Unseen: RaySense excels at identifying, understanding and alarming for events it hasn’t encountered before, such as cutting, climbing, lifting, and jumping over fences it wasn’t trained on. This unique feature allows it to adapt to new scenarios effortlessly.

2. “Yes” Detection Approach: Unlike other systems that focus on filtering out false alarms, RaySense is trained to specifically detect and respond to the events for which we want to trigger alarms. This approach ensures a focused detection mechanism, aiming to capture only meaningful incidents without the need for filtering false alarms.

3. Easy and Reliable Calibration: RaySense’s calibration process is straightforward and basic, designed to tune the AI to the specific infrastructure it’s protecting. This simplicity, combined with its ability to detect genuine incidents accurately, makes RaySense a more innovative and reliable choice, ensuring a hassle-free setup for your security system.

RaySense’s innovative use of DL, its targeted “yes” detection strategy, and its simple calibration process set it apart in the market, offering a more efficient and reliable solution for detecting anomalies.

The most economical way to protect a long perimeter

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 100km/62 miles with no power or electronics in the field. Using a rugged fiber-optic sensing cable results in the most cost-effective fence detection solution for large perimeters.

What is Distributed Acoustic Sensor (DAS) Technology?

Distributed Acoustic Sensor (DAS) Technology 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, minimal physical (acoustic or vibration) disturbances at a point in the fiber can make detectable changes in the interferometric signal.
