Praetorian Fiber Optic Sensing for Perimeter Security and Threat Detection
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.

Principle of Operation
Using a combination of Rayleigh backscatter and time of flight, the Praetorian determines the presence, location, intensity, and frequency of vibrations along an optical fiber in real-time.
Rayleigh backscatter responds to vibrations applied to the fiber. HAWKÍS signal analysis software allows the Praetorian to quickly determine the most likely origin of the vibration and report any error signals to security personnel without notifying an intruder of their detection.
The location of the vibration is determined using a "Time of Flight" calculation. When a laser pulse is emitted from the system a fast clock is started. As backscattered light is returned to the detector, it is recorded for further analysis and time stamped. Due to the speed of light being constant within a fiber, this timestamp corresponds to a distance on the fiber. For more on fiber optic sensing perimeter security, visit HawkFiber.com!
