The RaySense Distributed Acoustic Sensing (DAS) system redefines the fiber optic intrusion detection system category by turning standard single-mode fiber cables into a high-precision, 100km continuous sensor. While industry-standard systems often claim “AI integration” by merely performing visual classification on signal waterfalls (FFT), RaySense utilizes a proprietary Raw Signal AI engine. By analyzing the “DNA” of vibrations at the source, before data is compressed or distorted, RaySense achieves a level of threat discrimination and nuisance alarm rejection that traditional frequency-based sensors cannot match. To further bridge the gap between complex technology and field deployment, RaySense features Automated AI Calibration. This system autonomously maps your site’s specific environmental noise floor, eliminating the weeks of manual tuning typically required. The result is a truly “plug-and-play” infrastructure protection solution that offers pinpoint accuracy, zero power-in-the-field requirements, and the lowest Total Cost of Ownership (TCO) in the perimeter security market.
- Up to 100km/62 miles per processing unit.
- It can be used on the fence and underground with the same cable.
- Offline AI – No Monthly fee or hidden costs.
- Proprietary Raw Signal AI
The Architecture Breakdown of the RaySense
The RaySense system layout is engineered for simplicity and extreme durability, concentrating all intelligence into a single, rack-mounted Alarm Processing Unit (APU). By utilizing standard single-mode fiber optic cable as the sensor, the system eliminates the need for power, electronics, or communication hardware along the perimeter, creating a streamlined and maintenance-free architecture.
Centralized Processing: The APU resides in a secure, climate-controlled server room, connecting to the perimeter via a non-sensing lead-in cable.
The Sensing Fiber: Up to 100km of fiber (50km per channel) is attached to fences or buried, transforming every meter into a virtual microphone.
Zero Field Infrastructure: No electricity or grounding is required in the field, making the system immune to lightning, EMI, and RFI.
Virtual Zoning: The physical cable is divided into hundreds of software-defined zones, allowing for precise camera slewing and localized alarm triggers without changing the physical layout.

Here are five reasons why radar and thermal cameras don’t replace the RaySense
Radar and thermal cameras monitor what they can see. RaySense turns the entire fence line or buried fiber route into a continuous sensor, giving protection along long perimeters without leaving gaps between devices.
Radar and thermal cameras can be blocked or weakened by terrain, vegetation, buildings, parked vehicles, fence angles, or weather. RaySense detects activity directly on the fence or along the fiber path, without depending on a clear visual view.
Radar and thermal cameras may detect movement near or beyond the fence, but they do not confirm what is happening to the perimeter itself. RaySense detects direct activity on the fence or along the buried fiber path, such as cutting, climbing, lifting, digging, or tampering. That makes it a perimeter intrusion sensor, not just an area monitoring device.
Covering miles of perimeter with radar or thermal cameras usually requires many poles, power points, network connections, and maintenance. RaySense can protect long distances using passive fiber in the field, with no power required along the sensing cable.
RaySense is not only a detection sensor. The same fiber can also support communication infrastructure along the perimeter, helping connect remote areas, gates, cameras, or other field equipment. For long sites, this means the sensing cable can become part of the site’s security backbone, not just another standalone sensor.
Product Features:
Built to connect with the site’s security ecosystem
RaySense is designed to integrate with VMS platforms, alarm systems, access control, command centers, cameras, and RBtec’s Vidalert monitoring software. This helps turn fiber alarms into actionable events inside the systems operators already use.
Fence, Buried, and Hybrid Applications
The same RaySense platform can protect fence-mounted sections, buried routes, or mixed layouts, making it easier to standardize one detection architecture across complex sites.
Passive sensing cable in the field
The sensing fiber does not require power, network switches, field electronics, or cabinets along the protected route. This simplifies installation, reduces exposed equipment, and lowers maintenance across remote or hard-to-access perimeters.
Software-defined zones and centralized configuration
Zones, sensitivity, alarm logic, and detection settings are configured in software instead of through physical rewiring. This makes setup faster and allows the system to be adjusted as the site layout, risk areas, or operational needs change.
No proprietary sensing cable required
RaySense works with standard single-mode fiber, making it easier to install, repair, expand, and support using familiar fiber-optic installation practices.
How RaySense Perimeter Intrusion Detection Works
1. The sensor cable. A standard single-mode fiber optic cable is installed in a shallow, terrain-following trench along the protection line. Installation minimizes trenching, works in any ground type, and leaves no power, electronics, or maintenance in the field, with an operating life of more than 10 years underground.
2. Coherent light sensing (COTDR). The APU sends laser pulses down the fiber and measures microscopic changes in the backscattered light using Coherent Optical Time Domain Reflectometry, the Distributed Acoustic Sensing principle proven in pipeline and railway monitoring. Movement above the cable alters the light pattern at that exact point on the fiber.
3. AI classification and location. A two-layer deep-learning engine analyzes each vibration signature in real time, separating genuine threats (footsteps, vehicles, digging) from wind, rain, and animals. The system reports what happened and where, locating events to roughly 3 m (10 ft) and tracking multiple simultaneous intrusions.
