Dual-technology PIR with Anti-masking
The Next®+ Duo AM is a dual-technology digital detector designed to prevent false alarms due to interferences in residential and light commercial environments and to detect tampering. A passive infrared (PIR) sensor and a complementary active microwave sensor are combined in a single unit, giving Next+ Duo AM an unprecedented capacity to distinguish between the motion of a human body and any other disturbance.
Featuring advanced anti-masking capabilities, Next+ Duo AM continuously monitors its surroundings and produces alerts upon attempts to block its field of view. This advanced detector implements a new generation of patented technologies including FM Digital Signal Processing (FM-DSP), True Motion Recognition ™ with Fuzzy Logic algorithm (TMR), and state of the art 3D cylindrical optics.
The result is the industry's best detection accuracy, false alarm immunity, tampering detection, and ultimate long-term reliability – all in an attractive, easily installed device designed for home and office applications.
