Dynamic Dual-Technology Detector

The Duet is a professional-grade dual-technology digital detector, designed to prevent false alarms in harsh environments such as commercial and light industrial areas. Duet combines in a single unit two complementary advanced technologies - a highly sensitive passive infrared (PIR) sensor and an active Microwave sensor - achieving unprecedented detection, stability and immunity to false alarms.

The dual-element PIR detector includes a user-selectable 1 or 2-pulse counter, as well as advanced temperature-compensation circuitry for unsurpassed false alarm immunity. It also provides creep-zone detection for enhanced reliability and catch performance.

Duet implements a new generation of patented technologies, including advanced microwave DRO front-end utilizing Digital Signal Processing (DSP), dynamic software filtering of fluorescent interferences and more. The result is the industry's best detection accuracy, stability, false alarm immunity and ultimate long-term reliability - in an elegant, durable and easily installed professional device.

Duet Features

  • Dual passive infrared and microwave digital technologies for unsurpassed false alarm immunity and reliability.
  • Optimized signal processing of both MW and PIR channels for superior detection without false alarms.
  • High-sensitivity coverage up to 18m x 18m / 60ft x 60ft with anti-sabotage creep-zone.
  • Programmable 1,2 pulse counter for maximum immunity to false alarms.
  • Six interchangeable lenses with coverage pattern up to 140deg..
  • Adjustable vertical calibration.
  • 9-16 VDC power supply.
  • Optional swivel brackets for maximum mounting flexibility.
  • Durable elegant design suitable for any office, commercial or light industrial environment.

I installed this detector over one year ago, and Duet has not produced any false alarms. The easy setup and multiple mounting options improve its utility. The ability to configure the trip LED and silent operation increases aesthetic value. I think the higher price is worth the higher accuracy.

This motion detector is an excellent top of the line unit. Large coverage area, lots of space inside for wiring, and adjustable microwave unit. Setting it up the first time is a bit more involved than just slapping it on the wall since you should adjust the infrared angle and microwave range to suit your coverage area. No false alarms or failures in 3+ years of using these units. Well worth the price.
