DSIT Solutions Ltd. offers LightLine™ a dual purpose Fiber-Optic sensing solution for both Perimeter Intrusion Detection (PID) and Linear Infrastructure Monitoring (LIM) applications.

DSIT’s Fiber-Optic Sensing solution provides up to 100 km of a continuous surveillance per fiber optic processing unit through its advanced DAS (Distributed Acoustic Sensing) technology.No power infrastructure is required along the fiber optic cable

No power infrastructure is required along the fiber optic cable which can be buried underground or attached to a fence.
A single shelter houses the necessary equipment to provide up to 100 Km detection and processing capability.

The fiber optic cable is inherently immune to EMI/RFI or lightnin and is safe in the presence of explosive atmosphere.
A single standard, single-mode communication fiber in a directly-buried cable configuration, effectively provides the means for detecting surrounding signals.
DSIT PIDS/LIM LightLine™ solution is capable of accurately locating multiple simultaneous intrusions along the fiber, in real-time.
Natural environment or non-relevant man-made noises are automatically filtered in real-time by DSIT`s advanced signal processing algorithms, thus resulting in low false alarm rate.

Detection, localization and classification of targets of interest versus false or nuisance activity
User Interface
Operators’ user interface software enables display, recording, playback and event logging features. A dedicated Technician level user interface provides the necessary tools for system installation and calibration purposes.
