unum PIR Indoor Motion Detector
The PIR Motion Detectors unum are professional state of-the-art motion sensors engineered with the world’s best components and materials.
These detectors provide the highest degree of reliability in motion detection, without the risk of 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.
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.
Dual-element detector fields-of-view alternate between (+) and (-) polarity.
HighBar-qualified signal events are counted as “pulses” exclusively when polarity alternates. Depending on sensitivity setting, (+,-), (-,+), (+,-,+) or (-,+,-) will cause an alarm.
