The velum-C motion sensor is a curtain infrared that has the same main features as the velum wls sensor, but can be mounted on the ceiling up to a height of 6 meters.
Ksenia velum-C wireless devices use the latest generation fully bi-directional frequency band of 868MHz (each peripheral device acts as a receiver, which allows each data transfer to receive a confirmation message, which allows optimization of consumption and provides greater reliability than traditional
The sophisticated DPMS (Dynamic Power Management System) reduces interference, maximizes battery life and optimizes transmission power depending on the distance between different wireless devices.
The maximum protection of the entire system is ensured by the encryption of each communication packet with its own algorithm.

(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.
