The MX-40QZ creates an integrated detection, enabling the microwave detection area to synchronise the PIR detection area, achieving higher detection performance and preventing errors or false alarms. The MX-40QZs spherical lens provides a precise focal length to each of the multiple lens segments, enabling each segment to face its detection areas, creating detection Zones without disortion, bringing lens precision to a whole new level. Another key feature includes the noise reduction circuit which provides high -reliability performance against outside noise, such as electro-magnetic interference and especially noise from fluorescent lights, thus false alarms are greatly reduced.
