Next+ Duo

Dual-technology Digital PIR Detector

The Next®+ Duo is a dual-technology digital detector designed to prevent false alarms due to interferences in residential and light commercial environments. A passive infrared (PIR) sensor and a complementary active microwave sensor are combined in a single unit, giving Next+ Duo an unprecedented capacity to distinguish between the motion of a human body and any other disturbance.


Next+ Duo implements several 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 and ultimate long-term reliability – in an attractive, easily installed device designed for home and office applications.
