Distributed Acoustic Sensing (DAS) systems based on fiber optic cables offer several significant advantages compared to traditional perimeter security systems:
High Sensitivity and Precise Localization
Thanks to coherent reflectometry, DAS systems provide high sensitivity to vibrations and sounds across a wide frequency range from 5 Hz to 10 kHz. This allows determining the location and type of impact on the perimeter with an accuracy of 5-20 meters at distances up to 100 km.
Long Range and Scalability
A single DAS system can monitor up to 100 km of perimeter using just one fiber optic cable as the sensor. Combining up to 20 systems into a unified network enables coverage of a perimeter up to 1500 km long. Traditional systems would require thousands of local sensors to achieve this.
Covert Installation and Environmental Resilience
The fiber optic cable can be discreetly installed on a fence, in the ground, or underground without requiring power or maintenance. It is not susceptible to corrosion, resistant to electromagnetic interference and radiatio.
Intelligent Threat Classification
Advanced machine learning algorithms based on neural networks allow DAS systems to not only detect intrusions, but also classify the type of intruder (human, group, vehicle, animals), the nature and direction of movement, and distinguish tunneling from impacts on the fence. This minimizes false alarms.
Integration and Ease of Use
DAS systems easily integrate with video surveillance, access control, security lighting and other security systems. A unified operator interface, event log, automatic notifications, and remote monitoring capabilities simplify the operation of the perimeter security complex.In summary, fiber optic DAS systems are a highly effective and promising solution for protecting extended perimeters and critical infrastructure. Ksense successfully implements the K-DAS system for securing state borders, airports, oil and gas pipelines.
