Praetorian Fiber Optic Sensing for Perimeter Security and Threat Detection

Brand: Hawk Measurement Systems

The Praetorian Fiber Optic Sensing System can be installed along a fence or perimeter and can detect, identify and report any movements.

This system has limitless applications and can be installed on anything from explosive storage areas to farms and ranches.

The fast processing speed and pulse rate allow the Fiber Optic System to detect minute interferences that may otherwise go unnoticed.

Some examples of detectable activates include intruder movement along a perimeter, intruders cutting or climbing a fence, vehicle movement along a perimeter and digging, excavating or trenching.

The Fiber Optic Sensing system is crucial for keeping valuable assets secure and protected.
  • No time splicing, allowing zero chance for an intruder to go unnoticed
