At Hikvision, we offer optical fiber products that use light waves and optical fibers to detect and respond to environmental changes precisely. Our solution is perfect for perimeter intrusion detection, especially over long distances. At Hikvision, we offer optical fiber products that use light. Representing the next step in the evolution of Distributed Fiber Sensing, ONYX™ converts existing telecommunications fiber optic cable into a rich vibration, detection and ranging system. Government & Defense. Distributed Fiber Optic Vibration Sensing (DVS) is an advanced optical sensing technology that uses single-mode optical fiber (SMF, G652 recommended) as both the sensing medium and signal transmission carrier. Various events generating vibrations, such as a walking or running person, moving car, train, and many other vibration.
