Dual-Tech Motion Detector unum
The DT Motion Detectors UNUM are professional state-of-the-art
motion sensors engineered with the world's best components and materials. Every
aspect of these sensors provides the most reliable motion sensing with freedom from
false alarms. Additionally the UNUM series introduces in the market the only detectors
with trendy invisible lens, i.e. the lens integrated into the front cover thanks
to E.L.T.™ (Embedded Lens Technology) which takes advantage from decades of experience
in designing professional lens by adopting its own material to design the entire
cover too. DT Motion Detectors UNUM include two motion sensing systems: microwave
Doppler motion sensing and PIR motion sensing. Together, the two systems' signals
are evaluated by proprietary signal processing algorithms, which reject false alarm
conditions while detecting intruders.
The DT Motion Detector UNUM microwave system includes
a modern, compact, DRO-based micro-strip Doppler transceiver, with PCB "patch" antennas.
The Doppler signal is digitally processed to detect intruders and reject distractions.
Constant-motion signals (such as fans) are de-emphasized, and fluorescent light
frequencies are digitally removed. The PIR side starts with a EvenEye™ lens and
a top-quality infrared detector. Next, a modern DSP ASIC (patent-pending) converts
the infrared detector signal into digital form, for best reliability and stability.
Finally, the signal is evaluated by the ASIC's HighBar™ processor, for "best-in-class"
false alarm rejection with excellent intruder detection.
