PIR and Microwave Detectors Compared

PIR (Passive Infra Red) Detectors

PIR detection

  • PIR (Passive Infra-Red) presence detectors detect body heat and movement and are ideally suited to smaller spaces or where a defined detection pattern is required such as:
    • Offices
    • Boardrooms
    • Bathrooms & Toilets
    • Copier Rooms.


Microwave Detectors

Microwave Detection

  • Microwave presence detectors are sensitive to movement and are ideal for large spaces and areas that have an awkward shape or where fine motion detection is required.
  • Microwave detectors have a much greater coverage and higher sensitivity and can detect movement through glass. Careful consideration needs to be given to the location of microwave sensors.
