The person size is the area of the rectangle circumscribed around the person, as a percentage of the frame area. To ensure the correct operation of the detection tool, the it is necessary to select the size of a person in the range from the minimum value, depending on the frame width, to 75% of the frame width.
Note
Frame width means not the original resolution of the video image, but the compressed size that depends on the Frame size change parameter (see Configuring the Visitors counter detection tool).
