The DT6670 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 DT6670 an unprecedented capacity to distinguish between the motion of a human body and any other disturbance.

Utilizing patented digital processing techniques, controlled by microcomputer, that eliminate many components and noisy amplifiers, the detector solve the problems of distortion, added noise and saturation caused by analog circuitry. They employ the patent-pending True Motion Detection (TMDT) Technology, with an exceptionally high million-per-second sampling rate. The result is absolute detection coverage with superior immunity to false alarms. 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.

Thanks to the new cylindrical optics and spherical-shaped 3-D lens which is free of vertical adjustment with uniform detection sensitivity beginning at 0.3 meter (creep-zone) away from the detector up to a distance of 15 meters. New lens material protects against white light and strong UV rays assuring long lasting sensitivity. DT6670 sleek, ultra modern design is attractive in any home or office.
