Electromagnetic Spectrum: Radio Waves

Xandem Tomographic Motion Detector

Xandem uses radio waves to detect intruders in a store. It is a security system, but is different from others because it uses radio waves instead of microwaves to detect movement. It can go through dirt, and most things in its path. This technology uses separate motion detectors around the area and then they all link up and send any alarms to the processing unit.
