Microwave sensors, also known as Radar, RF or Doppler sensors, detect walking, running or crawling human targets in an outdoor environment.

Southwest Microwave developed the industry’s first bi-static microwave sensor in 1971, and has pioneered the development of flexible, reliable microwave links and transceivers for the protection of open areas, gates or entryways and rooftop or wall applications.

Microwave sensors generate an electromagnetic (RF) field between transmitter and receiver, creating an invisible volumetric detection zone. When an intruder enters the detection zone, changes to the field are registered and an alarm occurs.

Our microwave sensors are easy to install, provide high probability of detection, low nuisance alarms and resistance to rain, fog, wind, dust, falling snow and temperature extremes. Most operate at K-Band frequency, maximizing detection performance and minimizing interference from external radar sources.
