Motion detectors: what they are and how they work

Home » Insights » Motion detectors: what they are and how they work

The ever growing demand for security has led to a huge spread of motion detectors burglar alarms, considered the safest security systems to protect the home from unwanted intrusions. Theft in the apartment is a phenomenon that not only affects the economic side but the whole feeling of security that is linked to our home, consequently, the installation of indoor motion sensors is a way to feel safe and secure. ensure proper protection to our personal spaces.

What are motion detectors

Motion sensors, also called volumetric detectors, are mechanisms that detect any type of movement within a given perimeter. Installed to protect the home from intrusion by malicious people, they are normally integrated into an anti-theft system.

They are normally installed both outside and inside of the home, in transit areas such as corridors or stairs, or in individual rooms. The more elaborate systems allow the activation of specific programs which do not affect the use of domestic environments and which are triggered only when necessary, avoiding alarming for the movements of animals.

Motion sensors how they work

To understand how motion detectors work, it is good to clarify that, to intercept intrusions, they can exploit various technologies. Among the most used are:

– active infrared which create invisible rays and generate alarms if they are crossed;

– passive infrared that detect the difference in temperature between the environment and the foreign body that has entered the protected area;

– Microwave that detect any kind of movement.

Many sensors use multiple technologies at the same time, with the aim of minimizing the risk of false alarms.

Unum series dual technology motion detectors

Among the most advanced motion detectors on the market we can find the unum DT motion sensors: made with cutting-edge components and materials, they guarantee a very high degree of reliability in motion detection, minimizing the risk of false alarms.

The detectors of the unum series are unique on the market and are equipped with invisible and ultramodern lenses, integrated into the front panel thanks to ELT (Embedded Lens Technology) which uses the material of the lens itself also for the design of the entire front.

unum DT detectors are motion sensors dual technology, that is, they use two technologies for motion detection: microwaves doppler and infrared. These two different signals are interpreted at the same time by proprietary algorithms which exclude false alarms while detecting unwanted intrusions.

The microwave section is composed of a modern and compact microstrip Doppler transceiver, based on DRO and with patch antenna on PCB. The signal comes digitally processed, so that it is as reliable as possible in intrusion detection and excluding possible disturbances. Repetitive motion signals such as, for example, fans are filtered and, in the same way, frequencies deriving from fluorescent light are digitally eliminated.

The IR section uses an Even Eye lens combined with a high quality infrared detector. The infrared signal comes converted into digital form by a modern DSP ASIC (patent-pending), improving reliability and stability. The signal is then evaluated by a HighBar ASIC processor, to achieve the exclusion of false alarms while maintaining an excellent degree of intrusion detection.

The advantages of unum motion detectors

The motion detectors of the unum series have a sober and minimalist aesthetics, unique in the panorama of anti-intrusion sensors, developed thanks to in-depth studies and with the advice of architects and designers in order to create sensors that can be perfectly integrated into the most diverse interior architectures. The result is a detector that becomes active subject of furniture, no longer a necessary forcing.

Thanks to ELT technology, the result of decades of experience in the design of professional lenses for motion detection, in unum detectors the lens has literally disappeared from the sensor profile, being completely integrated into the detector front itself, entirely made of HDPE (advanced material with which the lens is made).

Therefore, those unsightly LED lights, often annoying, are not visible outside the sensor. Regardless of the technical characteristics, all models have the same design and the same dimensions, allowing you to choose the most suitable sensor for each environment and always maintaining the same aesthetic style, thus avoiding the “harlequin” effect that can occur by installing different sensors in different environments.

Finally, unum motion detectors have an range of operating temperatures really very wide and, in compliance with the Ksenia Security philosophy, they use components such as DSP ASIC with very low energy consumption.
