velum DT AM Dual-Technology Motion Detector

Ksenia velum is a motion sensor dual technology with Anti masking which can be installed both outside and inside.
It may simply mean that the sensor projects a dual Technology barrier shielding (infrared and microwave) which completely fills the area to be protected by covering it evenly, precisely as with a veil.

velum detectors are motion sensors made with advanced professional components and materials among the best in the world. From every point of view, these sensors guarantee the highest degree of reliability in the detection of the movement, without incurring false alarms.
The motion detector velum includes two technologies for motion detection: microwave doppler effect and infrared. Together, these two signals are interpreted by proprietary algorithms that reject false alarms and detect unwanted intrusions.
Section microwave sensors velum includes a transceiver Doppler microstrip modern and compact.
The Doppler signal is digitally processed to obtain the highest degree of reliability in intrusion detection and exclusion problems.
The signals of repetitive motion are filtered so as frequencies resulting from fluorescent light are eliminated in digitally. The section to the IR acts with a lens combined with an infrared detector of high quality.
Finally, the signal is evaluated by a processor, for obtaining the exclusion of false alarms while maintaining an excellent degree of intrusion detection.
The masking of the lens of the infrared analysis is carried out using infrared LED active, able to detect any obstacle placed in the vicinity of the lens.
velum detectors are the ideal solution can protect situations such as canopies, porches, below balcony, windows etc.
The sensor velum is synonymous reliability and high safety, not only from the qualitative point of view, but also against sabotage attempts, given that integrates a station with accelerometer flexible and functional even in installations with the hub and a micro switch for front opening.


velum-C detector is a curtain movement detector that has the same main characteristics as velum wls detector; it can however be installed on the ceiling with a 6m vertical flow.
In this way, positioned at the center of the frame, it ensures its complete coverage, creating an insurmountable barrier to any intruder.
