What is a Dualtec or Microwave Detector?
A ‘Dualtec’ is a detector that has two detection devices. The most common type is a Microwave/P.I.R but can be any combination of detection devices (Ultrasonic and Seismic being the other most popular). A Microwave detector works by sensing the physical movement of an object (person). These units would be installed in an area that may be prone to temperature fluctuations as the P.I.R and the Microwave circuits need to be activated simultaneously to cause an alarm.
