The SWAN-1000 detector is a combination of PIR & MW detectors, providing protection from intruders by PYRO sensor element and MW antenna (based on Doppler concept). Using the microprocessor technology, based on signal processing via ASIC system, the SWAN-1000 eliminates false alarms caused by small animals and pets.
The Microwave Technology allows to detect the intruder also through the wall. For example if you install the detector inside garage, a both indoor and outdoor detections will be possible.
