We used fiber optic under Distributed Acoustic Sensing (DAS) to detect all uncommon activity along the perimeter area. Since this solution can be installed in buried (covert) so our solution will be more difficult to detect and defeat compare to CCTV, radar and similar other technology which easy can be detected and locate. We also provide integrated function on top of your current CCTV solution and this integration will bring the complete solution between location, event and image.
