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 FeaturesIntelliFIBER 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 IntelliFIBER Features (continued)(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

Components to Match to the SITE FeaturesComponents to Match to the SITE Features
• singe standalone sensor, to large network interfaced to control and display systems
• new cable types for minimal field hardware (and cost)
• other sensors and local inputs and outputs
• methods to handle gates
Advancements - New Sensor CablesAdvancements - New Sensor Cables
• Four different cable types to best match the application
– 2-core– 4-core– 4-core plus power– Armoured for vandalism protection
• Available in various continuous lengths• 1000 m (3281 ft.), 300 m (1000 ft.), 200 m (656 ft.) and 100
m (328 ft.)

Fiber Types & Installation
New Sensor CablesNew Sensor Cables
• IntelliFIBER has 4 different sensor cable options:
– Dual fiber cable for single pass (built-in return) for detection only
Sensor Cables Sensor Cables (Continued)(Continued)
– Quad (4) fiber cable: 2 for detection, 2 for data transmission in a networked application
Sensor Cables Sensor Cables (Continued)(Continued)
– Quad (4) fiber with 2 #14 AWG copper conductors for DC power distribution through same single cable on the fence, or power distribution protection
– Saves cost of separate power distribution network– Also vandal-resistant armoured version

CalibrationCalibration
• To best detect the intruder and not the environment
• Can do locally at the perimeter with testing for cut and climb– use of configuration module at each zone
• New feature – can use StarNeT interface for centralized response recording of zones for entire perimeter

IntelliFIBER PerformanceIntelliFIBER Performance
Test Details:
• different fiber types running concurrently on same fence• Calibration for climbs and cuts (simulated) Pd; see plot for
typical along cable performance and test environment• Long term monitoring for false and nuisance alarms (FAR/NAR)
versus environment– Sample result, nominal 100m. zone, 4+2 cable; running since
February 2003 (1062 logged hours):-less than 0.00 combined false and nuisance
alarms/zone/day for IntelliFIBER -compares well to 0.02 with Intelli-FLEX
*performance dependent on specifics of fence, calibration etc.
