A fiber intrusion detection system is a security technology that uses fiber optic cables to detect disturbances or intrusions along a perimeter. These systems are designed to identify unauthorized access attempts by sensing changes in the light signals transmitted through the fiber optic cable.
How Fiber Intrusion Detection Systems Work
Fiber optic intrusion detection systems work by monitoring the characteristics of light traveling through a fiber optic cable. Changes in light properties, such as intensity or phase, can indicate a disturbance such as someone cutting, climbing, or even touching the cable.
Key Principles
- Light Transmission: The core principle is to transmit light through an optical fiber.
- Disturbance Detection: External disturbances cause slight changes to the optical fiber, affecting the light signal.
- Signal Analysis: Sophisticated electronic systems analyze the changes in the light signal.
- Alarm Trigger: When a significant change is detected, an alarm is triggered.
Types of Applications
Fiber intrusion detection systems are flexible and can be deployed in a variety of ways:
- Fence-Mounted: They can be attached directly to a fence to detect attempts to climb over or cut through. FiberPatrol FP1150 is an example of a system that can be fence-mounted.
- Buried: These systems can be buried underground to protect against digging or tunnelling activities. The FiberPatrol FP1150 is designed to also protect against underground threats.
- Wall-Top: They can be installed on top of walls to provide a barrier against climbing or breaches. According to the provided reference, FiberPatrol FP1150 can be used in wall-top configuration.
- Data Conduits and Pipelines: These systems can protect infrastructure like data conduits and buried pipelines by detecting attempts to access or tamper with them. FiberPatrol FP1150 is designed for such applications.
Advantages of Fiber Intrusion Detection Systems
- High Sensitivity: They are highly sensitive to even slight disturbances.
- Long-Range Coverage: They can monitor long perimeters with minimal infrastructure.
- Weatherproof: The system can operate reliably in various environmental conditions.
- Difficult to Bypass: They are hard to tamper with without detection.
Example of a System
The FiberPatrol FP1150 is an example of a fiber intrusion detection system that demonstrates the capabilities of such systems, as it can be deployed in the configurations described above.
In summary, fiber intrusion detection systems utilize changes in light transmission through fiber optic cables to detect and signal intrusions, offering a robust and versatile security solution for a variety of applications and environments.
