Attach the detector to the bracket, and change the detecting angel and distance by adjusting the
installation height and the bracket. It is advised to install the device at a height of approximately 2
meters.

to horizontal movements, so it’s best to be aim the device at a 90 degrees’ angle to a person’s
walking direction.
