The detector is buried in the center of the circle the man walks around.
The radius of the circle is about 15 meter.
The right window is a graphic representation of the detector data sent to the PC connected to the detector via serial interface (RS485). The PC is within the white car. The vector in the window shows a direction to the man, the vector's length represents a seismic power of the man steps the detector received.
