Nxtar Fiber Optic Intrusion Detection System is based on the theory of “Interferometer”, utilizing fiber as a highly sensitive medium, indirectly or directly sensing pressure, vibration

Utilizing “Interferometer” principle, the 2 arms of sensing fibers are made equal in length. When one arm senses pressure or vibration, the other one will compare and analyze the signal to determine if this is an intrusion or unwanted alarm.
