The Z-Wave sensor is equipped with Z-Wave500 series main control chip. It is a passive infrared intrusion sensor that adopts Energy Integration Logical Processing, Random Dynamic Time Segmentation & Digital Signal Processing Technologies. With precise columnar Fresnel lens, it can increase its energy receiving efficiency and sensitivity without false alarm. In conjunction with advanced software technology, it will make an accurate judgement 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 sensors 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 3 years.
