UltraWave is a volumetric, fully digital, bi-static microwave sensor that generates an invisible field of energy between a transmitter (Tx) and receiver (Rx). When an intruder enters the field, an alarm is generated. UltraWave is ideal for providing perimeter security as well as protecting gates and sally ports.

Microwave Intrusion Detection Sensor
XField
Terrain-Following Volumetric Sensor
XField is a terrain-following volumetric sensor that consists of vertical electrostatic fields generated around sets of parallel wires. If an intruder breaches the fields, an alarm is generated. XField is designed for high-security environments and can be used in free-standing, fence-mounted, roof and wall applications.
Above Ground Sensors FAQs
What are Above Ground Sensors?
Above ground perimeter intrusion detection sensors use volumetric electromagnetic fields to detect intruders. The sensors are free-standing and can be installed in open areas like gates or roof tops.
Why Above Ground Sensors?
Above ground sensors enable flexible, terrain-following solutions that can meet a variety of security challenges, including protection for perimeters, gates, sally ports, roof tops and walls.
What are Microwave Sensors?
Bistatic microwave sensors generate an invisible field of energy between a transmitter (Tx) and receiver (Rx). When the field is altered by an intruder walking, running or crawling through it, an alarm is generated.
What are Electrostatic Sensors?
Electrostatic sensors create a static electric field around charged objects – primarily wires for perimeter security applications. When the field is disturbed, an alarm is triggered.
