What is RF970 fiber-optic intrusion detection system and Why Do We Use Them?

Fiber Optic Intrusion Sensor

Raycom Product Page

Perimeter intrusion detection systems are used in external environments to detect if an intruder is attempting to breach the perimeter and can protect critical operations in sensitive government or commercial areas, nuclear power plants, prisons, manufacturing, border protection and other facilities.

Fiber Optic Sensing Detection Principle

The Perimeter Intrusion Detection System is a powerful vibro-acoustic sensor using a typical single mode fiber optic cable.
Distributed Acoustic Sensing (DAS) technology and Distributed Vibration Sensing (DVS) technology are used to monitor fiber optics for different applications. The fiber optic cable is highly sensitive to pressure, acoustics and motion, which makes it capable of detecting vibrations transmitted through fences, soil or surfaces.

Installation Layout

The system utilizes fiber optic cable, the most economically competitive technology available for long distances. With only one Alarm Processing Unit (APU) covering 100 km/62 miles, and a rugged fiber optic sensing cable, only a few components are needed to provide the most cost-effective solution for large perimeters.

Features

- Up to 100 kilometers/62 miles per processing unit.
- Whole perimeter resolution within 3-20 meters/10-60 feet
- Terrain-following installation
- Flexible software-based zoning configuration
- Concealed deployment of buried high-sensitivity fiber optic sensors
- Detects and locates multiple simultaneous intrusions throughout the fiber
- Sensing standard single-mode fiber
- Distributed Acoustic Sensing (DAS) technology
- Can be used in both fenced and underground locations using the same cables and controllers
- No electronics or power required in the field
- IP-based remote control and monitoring - Software-based zones
- Intrinsically safe in explosive environments, immune to electromagnetic interference and lightning strikes

Fiber Intrusion Detection System

The fiber intrusion detection system positioning-type fiber optic intrusion detection system designed for long-distance perimeters has real-time monitoring and precise positioning functions, which can quickly detect and locate threatening behaviors and intervene in time to prevent illegal behaviors from happening.

Fiber Optic Sensing Detection Principle

Perimeter intrusion detection systems are systems used in the external environment to detect if an intruder is trying to breach the perimeter. With one of the most innovative fiber optic monitoring capabilities on the market, Raycom provides 100% perimeter coverage for long-distance applications with no gaps between sensors. The fiber optic cable is the sensor.
Fiber intrusion detection system is a powerful vibroacoustic sensor that uses a typical single-mode fiber optic cable. Distributed Acoustic Sensing (DAS) technology and Distributed Vibration Sensing (DVS) technology are used to monitor different applications of fiber optics. Fiber optic cable is highly sensitive to pressure, acoustics, and motion, which allows it to detect vibrations transmitted through fences, soil, or surfaces. The fiber intrusion detection system monitors vibration signatures over the length of the fiber optic cable, locates intrusion events, and classifies specific signatures based on detection algorithms.
Deploying the Raycom fiber optic intrusion detection system using a single fiber optic cable is an excellent choice for reliable perimeter security over a range of 5 to 100 km/3 to 62 miles. The system can detect and locate any intrusion within 3-20 meters/10-60 feet of the entire perimeter. In addition, the system can provide unlimited coverage by connecting to other network controllers.
