Fiber Optic Perimeter Alarm System Vibration Precise Positioning
WORKING PRINCIPLE
Using φ-OTDR (phase-sensitive Optical Time Domain Reflectometry) technology, the system transmits continuous laser signals through fiber optic cables. Any intrusion causing vibration alters the phase of Rayleigh backscattering, enabling the server to pinpoint the exact intrusion location with ±2m accuracy and trigger real-time alarms and security responses.
FEATURES & ADVANTAGES
Precise positioning with ±2 meters accuracy for fast response.
Flexible installation on perimeter walls using vertical mesh, roll mesh, or locking grid.
High resistance to interference, unaffected by lightning or electromagnetic noise.
Supports integration with radars and other multi-layered security systems.
