PIR- Motion Detector series unum

The PIR Motion Detectors unum™ are professional state-of-the-art motion sensors engineered with the world's best components and materials. 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.

Alarm processing

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.

Why unum?

  • because they are “state-of –the-art” Professional Motion Detectors realized with the very best components and materials to guarantee, at first place and without compromises , the highest possible degree of reliability available from the most modern Technologies
  • because they have a unique aesthetic- minimalist and discreet- different from the rest, being the result of many studies and suggestions collected from Interior Architects and End-users, who wanted something that could actually merge, integrate with their architecture styles to the point to become themselves active players to that instead of being something “not too nice but necessary to be installed” to the purpose of having an intrusion system up and running
  • because unum detectors apply the new ELT™ Technology (Embedded Lens Technology), which takes advantage from decades of experience in designing professional lens for motion detection purposes, thus enabling to achieve the objective to literally make the lens disappearing from the detector profile, thanks to very sophisticated techniques which also use the same special material of the lens (HDPE), to basically allow it to be fully embedded, completely integrated in the front cover itself
  • because they do not need, unlike other products in the market, to have on their front side all those colored lights (LEDs) which very often the installers need to disable because too annoying for the end-customers
  • because all the different detector models, although having different functions, like as the simple PIR or Dual-Tech, with or without Pet Immunity, all of them have the same design and size, so to avoid the unpleasant view of different detectors shapes on the walls, too often in the same room or environment
  • because they have a truly wide operating temperature range
  • because, they are eco-friendly, in line with Ksenia Security Company’s belief, all unum utilize components like as DSP ASIC with very low consumption.
