The number of people counter required is dependent on the height of the ceiling and the width of the entrance. You may key in the data over to have an estimation of the number of cameras. The counting width is between 2 heads closed to each side of entrance. The view width is between 2 foots closed to each side. However, only head width is really working width, not foot width.
If your entrance not often get busy traffic, most of visitors should pass the entrance in the middle, you can directly consider the foot view width.
