PIR-Zwave is a digital micro-control intrusion detector adopting Energy Accumulation Logical Processing& Random Dynamic Time Segmentation Technology. With precise columnar Fresnel lens, PIR-Zwave can increase its energy receiving efficiency and sensitivity without false alarm. In conjunction with advanced software technology, it will make an accurate judgment between real intruder &interference factors that may cause false alarm. Superior ability to detect &prevent false positives.The pulse number is optional, suitable for kinds of residential constructions, preventing false positive&false negative that other ordinary indoor detectors cannot do. Its performance is far beyond other ordinary PIR alarms. Besides, we use large capacity built-in battery & special power saving solution, battery working life is up to 2 years.
