Fiber Optic Sensing Perimeter Security Products

As a leading provider of fiber optic sensing perimeter security products, HAWK's Praetorian Fiber Optic Threat Detection Sensor Systems can be installed along a fence or perimeter to 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 Threat Detection System to detect minute interferences that may go unnoticed. Some examples of detectable activities include intruder movement along a perimeter, intruders cutting or climbing a fence, vehicle movement along a perimeter, and digging, excavating, or trenching. This fiber optic sensing perimeter security product is crucial for securing and protecting valuable assets.

Principle of Operation

Using a combination of Rayleigh backscatter and time of flight, the Praetorian Fiber Optic Sensing Perimeter Security System 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. HAWK's signal analysis software allows the Praetorian System to determine the most likely origin of the vibration quickly 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.
