The MX series 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 series 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.
