Q：About fall detector's height judgment methods,for the wall-mounted method, judging a person's height is relatively easy to understand, but how does the ceiling-mounted method determine a person's height?

A：

Both ceiling-mounted and wall-mounted methods can determine a person's height. By analyzing the radar waves reflected off the human body, the device can roughly identify the shape of the body's surface, as well as the distance and angle relative to the device. Combined with input installation details (such as mounting method and height), it then calculates the person's position and height.
