The XField sensor from Senstar Inc., is a terrain-following volumetric sensor that creates an electrostatic field around a set of four or eight parallel field and sense wires that causes its processor to sense changes when events - such as intruders penetrating the wires - take place. The technology is used in free-standing, fence-mounted, roof and wall applications. The system's tall, narrow, well-contained detection zone enables the sensor to be installed in a wide variety of applications and minimizes nuisance alarms caused by nearby moving objects. Features include: Direct-to-Digital Signal Processing; Enhanced digital signal processing algorithms; and 4-wire or 8-wire configurations. It is designed for use at nuclear power plants, correctional facilities, critical infrastructure sites, data storage centers, oil refineries, ports, water treatment facilities and more.
