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.

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
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.


Installation Options
We offer tailored installation solutions to meet customer needs, considering factors like safety, environmental conditions, and ease of maintenance.
Fence Mounted Intrusion Detection
- Hung on for all fences, including chain link, welded mesh, and fencing, mounted top or bottom.

- With a probability of detection (POD) higher than 95%, climbing and cutting can be identified, and positioning precision is up to ±1 meter.
Wall Mounted Intrusion Detection
- Installed along a wall or structure, typically placed below or outside the surface.
- Provides detailed detection of movement near or on a wall, particularly useful for monitoring vulnerable entry points or windows.
- Ideal for protecting facilities with walls or perimeters, such as warehouses, data centers or residential buildings.
Covert-Buried Mounted Intrusion Detection
- Fiber optic cables are buried underground, suitable for all soils, usually along the perimeter or specific areas of interest.
- Detect intruders before they enter the site, regardless of any ground disturbance, footsteps, vehicle movement or digging.
- Suitable for protecting sensitive or areas without physical boundaries, high concealment, providing a high level of security.

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.
