Fiber Optic Intrusion Detection System for Fence, Wall and Buried Applications
The RF970 is a perimeter intrusion detection system that can be mounted on a fence, buried in the ground, or deployed in a top-of-wall configuration. It can also be used to protect data pipes and buried pipelines.
Performance Features
Supports virtually all fence types
If the sensor cable is cut, detection continues up to the cut position
Provides a complete cut prevention configuration
Reliably detects intrusion in the presence of non-localized ambient noise
Advantages of fiber optic sensors
Fiber optic sensors are ideally suited for sites that are sensitive to electromagnetic energy. These sensors are immune to EMI and lightning, intrinsically safe in explosive environments, and require no power supply or conductive components in the field. Other benefits include unused fiber optics that can be reused for other applications, a 25+ year cable life, and a cut-proof configuration (when supported by the sensor).
