Dual Tech Pet-Immune Anti Masking unum™ series

The DT-PI-AM 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-PI 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-PI-AM 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.


Masks are detected by alteration of the normal PIR/microwave-signal balance that arises from everyday activities around the sensor within about half of the set microwave range. For cases where there are continual microwave motion signals, this mid-range mask detection can be disabled by moving JP1. Additionally, a secured zone (within 1m of the sensor) is monitored. A person entering this zone and bringing hands near the sensor will initiate an accelerated mask detection process. A flashing red LED and open Mask relay indicate masking situation.


The DT-PI Motion Detector UNUM is designed to allow the presence of pets (10kg or lighter) without signaling an alarm. It includes a special micro-element lens array that produces much stronger optical signals for humans than for pets of 10kg or lighter.
Furthermore, the optical sensitivity of each DT-PI Motion Detector UNUM is factory-calibrated to ensure accurate discrimination between humans and pets.

NOTE: Pets come in many varieties. Some pets (especially larger ones with very short hair), even if lighter than 10kg, may produce enough infrared radiation to cause alarms. DT-PI Motion Detector UNUM users are strongly advised to test the sensor with their own pets, in order to verify that the DT-PI Motion Detector UNUM will not signal an alarm when their pets are moving within its fields of view.

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
