Components of FOIDS

Our control host and fiber optic cables (sensors) provide an efficient and scalable intrusion detection system that can monitor large areas with high sensitivity and minimal maintenance.

With competitive price and timely delivery, Raycom sincerely hope to be your supplier and partner.

Control Host

The Control Host processes data from the fiber optic sensor, analyzes signals for disturbances, and triggers alarms when an intrusion is detected. It includes a monitoring and control interface, enabling integration with other security systems.

Fiber Optic Cable( Sensor)

The Fiber Optic Cable (Sensor) acts as the detection medium, transmits optical signals and detects interference caused by intrusion along its length. It provides wide coverage, is resistant to harsh environmental factors, and provides distributed sensing with minimal installation complexity.

Types of Fiber Cable

In a fiber optic system, single-mode fiber and multi-mode fiber differ primarily in their design and performance characteristics.

• A core of approximately 8-10 microns in diameter that allows only one mode (path) of light to pass through.
• Provides higher bandwidth, supports longer distances (up to several kilometers), with less signal loss and dispersion, making it ideal for long-distance applications.
• Used for large-scale, long-distance perimeter or infrastructure monitoring.

• It has a bigger core (diameter of 50–100 microns), which permits the simultaneous propagation of several light modes.
• Applications requiring shorter distances—typically less than 2 km—are better suited for it.
• Used for localized, small-scale fiber optic intrusion detection systems monitoring shorter distances.

Technologies of Fiber Optic Sensing

All three types of sensors have their advantages and can be selected based on the specific security needs, monitoring range, and sensitivity level required for your application. Distributed Acoustic Sensing

• Uses the entire length of fiber optic cable as a sensor, detecting acoustic disturbances by measuring light backscattering. It offers long-range, continuous monitoring, making it ideal for large-scale applications like perimeter security, pipeline, and border monitoring.

Fiber Bragg Grating Sensor

• Include fiber segments that can detect variations in pressure, tension, or temperature thanks to their distinct reflecting wavelengths. They provide precise location-based detection, making them suitable for monitoring specific areas like gates or entry points with high sensitivity.

Interferometric Fiber Optic Sensor

• Use light wave interference to detect minute changes in temperature, pressure, or vibrations. These sensors are perfect for high-security areas where accuracy is essential for identifying little disturbances because of their great sensitivity and accuracy.

• Safeguards critical infrastructure, including communication towers, water treatment installations, and power plants.
• Detects invasions, physical disturbances, or unlawful entry, ensuring continuous monitoring of sensitive locations.

• Protects large private estates, ranches, and high-profile residences.
• Provides advanced, long-range monitoring for high-net-worth individuals, ensuring their properties remain secure from potential intruders or trespassers.

• Used to secure airport runways, terminals, and port facilities.
• Detects movement along the perimeter in real-time, preventing breaches or suspicious activity near critical assets.

Frequently Asked Questions

How does a fiber optic intrusion detection system work?

Answer: A fiber optic intrusion detection system detects disturbances or vibrations along a fiber optic cable. These disturbances are caused by intrusions, such as fence climbing, digging, or cutting, which generate vibration signals. The system analyzes these signals to identify and alert on possible intrusions.

What are the advantages of using a fiber optic intrusion detection system over traditional security methods?

Answer: Fiber optic systems offer high sensitivity, low false alarm rates, and real-time monitoring. They are immune to electromagnetic interference, ensuring stable performance in harsh environments. Additionally, they can cover large areas like perimeters, fences, and sensitive facilities with fewer maintenance requirements.

How accurate is alarm detection?

Answer: The embedded structure and advanced signal processing technology of our fiber optic alarm systems ensure high accuracy. By using high-frequency and low-frequency analysis, the system can distinguish between intrusion signals and environmental interference, providing accurate alarm notification without unnecessary false alarms.

What is the response time of the system?

Answer: Our system has a microsecond-level signal processing response time, allowing it to detect intrusions and send alerts almost instantaneously, ensuring prompt action can be taken to mitigate potential threats.

What kind of maintenance is required for the system?

Answer: The system requires minimal maintenance. Routine checks on the fiber optic cables and signal processing units are recommended, but due to its durable design and resistance to environmental factors, the system is generally low-maintenance.

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.
