People Tracking Radar
Functional principle
The people tracking radar (Doppler radar) transmits electromagnetic waves that are reflected by objects. The reflected radiation from moving objects has a different frequency than the transmitted radiation (Doppler effect), which is used to detect and track people. The data is sent to a server for processing and visualizing.
