Next+ Duo AM

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.
