Ksenia velum is a dual tech motion sensor with anti-masking that can be installed both outdoors and indoors.
Velum motion detectors are made of the most modern components and materials available, so they can be the most modern professional detectors.
The velum motion sensor uses two technologies: microwave doppler and infrared.
The velum outdoor curtain infrared is an ideal solution for protecting places such as canopies, porches, pools, windows, etc.

(DT) Dual-Tech function
The UNUM DT motion detector contains two motion detection technologies: microwave doppler and infrared.
Together, these signals are interpreted by our own algorithms, which filter out false alarms and detect unwanted intrusions.
The microwave part of UNUM DT sensors has a modern and compact DRO-based Doppler microprocessor receiver and is connected to the panel with a patch antenna.

(AM) Anti-mask function
Masking is activated when the baseline PIR/microwave signal balance changes.
