PIR and Microwave Detectors Compared
PIR (Passive Infra Red) Detectors
- 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:
- Bathrooms & Toilets
- Copier Rooms
- 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.
