Intelli-FIELD is a terrain-following, volumetric sensor that creates an electrostatic field and sense wires. The resulting zone of detection is high and narrow and surrounds the wires. Typically, a four-wire system (two field wires and two sense wires) is used for a field approximately 2.5m high, 1.0m wide at centre and up to 150m long. The wires are mounted on freestanding posts or on a fence, adjacent to or between physical barriers. In controlled applications, the wire spacing may be altered and the wires may be mounted on the walls, roof and other structures. For higher fences, six-wire and eight-wire systems are available to extend the height of the detection field to greater than 5.0m. The wires present a visible, formidable barrier to the potential intruder..

The Intelli-FIELD system is the next generation of Senstar-Stellar's proven E-Field sensor technologyand is easily retrofitted to existing Series 600, 680, and 800/5000 systems. Its digital signal processor is designed to significantly improve performance and reduce False Alarm Rate/Nuisance Alarm Rate (FAR/NAR).

An innovative electronic design allows the Intelli-FIELD system to operate in complete isolation from any electrical ground reference and when compared with previous electrostatic sensors, a much lower voltage is used to excite the field generating wires.

The electronic processor also automatically adjusts and calibrates the output signal strength to the transducer environment.

The enhanced design reduces the criticalilty of the electrical field components and minimises the effects of environmental contamination of the insulators.The result is less maintenance and simpler installation.

Powerful digital algorithms analyse the signal of each sense wire individually and eliminate alarms from signals caused by birds and vegetation. The signal processor is able to recognise the signal patterns caused by the onset of heavy for, light mist, or rain. The net effectis an advanced electrostatic field sensor that performs with virtually no nuisance alarms from most environmental causes and with increased probability of detection.

The Intelli-FIELD processor analyses a compound signal consisting of amplitude change (mass of the intruder), rate of change (movement of the intruder) and the time the intruder is in the detection field. When these changes occur within specified limits, and intrusion alarm is activated. Intelli-FIELD will detect a mass of 35kg moving at a speed between 5cm per second, with a probability of detection greater than 99%.

A simple hand-held Configuration Module enables the user to easily set the parameters for each zone of the single/dual zone processor and monitor alarms locally. Optionally, with a multiplexed adapter, parameters can also be adjusted andmaintenance diagnostics analysed from centralised monitoring and control systems.
