Young American company Xandem Technology (pronounced /ˈzan-dem/) specializes in the production of unique alarm systems that have no analogues anywhere in the world. The fact is that the motion sensors used to track objects do not use optical or thermal sensors, but radio waves. According to the manufacturer himself, their principle of operation is similar to that used in medical tomographs. They are called accordingly - Tomographic Motion Detection (TMD).
The main advantage of these sensors is that they are able to "see" through walls, which is not available to other solutions. At the same time, a system consisting of several sensors and one control device can cover an area of about 20,000 square meters. meters.
TDMs are easy to install, they can be hidden so that no one will ever guess about the presence of any sensors in the room at all, they do not respond to various small interferences, such as small animals or insects.
The company is located in Salt Lake City, Utah. Its founder, Joey Wilson, worked for a long time at the University of Utah, doing research in the field of radio waves. One fine day, he noted that the technologies he developed could be used in surveillance systems.
Having borrowed about 100 thousand dollars from relatives and friends, having received a grant from his native university, Wilson managed to found a new company. He is confident that the systems he has developed will be in great demand both by companies and ordinary consumers and xandem a great future awaits.
