Presentation Overview: 

Presentation Overview What is IntelliFIBER? Advancements Field Applications and Tests Conclusions

What is IntelliFIBER?: 

What is IntelliFIBER? Disturbance-sensitive fiber optic cable is installed on existing chain link/metal fences Cables sense vibration along fence fabric caused by climbing, cutting or lifting Using sophisticated adaptive algorithms, the signal processor monitors cable signals to separate intrusions from environmental effects and produce valid alarms

IntelliFIBER Features: 

IntelliFIBER Features Detects attempts to cut, climb-over or lift the fabric of metal mesh fences Why fiber? –latest technology sensor cable is applicable to long zone lengths, very resistant to lightning, EMI, RFI Monitors up to 2000 m (6256 ft.) of sensor cable per zone Allows independent calibration of cut and climb scenarios for each zone Features “Adaptive Algorithms” which virtually ignore weather related events

IntelliFIBER Features (continued): 

IntelliFIBER Features (continued) Provides independent intrusion and supervision alarm outputs for each zone Available with either relay outputs or multiplex interface to: Intelli-FLEX/FIBER Central Controller StarNeT 1000 Senstar 100 Backward compatibility with Intelli-FLEX Fiber optic interface is achieved through a daughter card on the Intelli-FLEX processor Proven digital processing, identical to Intelli-FLEX

How Does IntelliFIBER Work?: 

How Does IntelliFIBER Work? A laser diode transmitter sends out infrared light at 785 nm A splitter/analyzer in the receiver separates the horizontally and vertically polarized components of the light A comparator looks for changes in the ratio of horizontally and vertically polarized light changes are created by micro-movements of the fiber optic cable ratio is independent of total beam intensity, which does change with temperature The change signal is converted into an electrical signal, amplified and sent to the processor for analysis
