People Counting 15 i To further understand these tables note that eEmpty cells within the table indicate that these configurations are not supported by the people counting e Any camera lenses or CCD sizes not included in these tables are not supported by the people counting e Ceiling heights lower than 9 5 feet and higher than 25 feet are not supported by the people counting feature Ifyou are working with a ceiling height that falls within the range of 9 5 feet and 25 feet but the exact height is not listed in the tables follow these steps first to determine that your ceiling height is supported and then to calculate the doorway width a Determine whether your ceiling height is supported for the camera lens you are using by referring to the table that corresponds to the CCD CMOS being used and ensuring that doorway widths display for the two heights between which your ceiling height falls For example if you are using a 1 2 CCD CMOS and a 3 6 mm lens and your ceiling is 12 feet high you can verify that this ceiling height is supported because doorway widths are available in the 9 5 ft Height column 19 ft width and the 15 ft Height column 29 ft width b If your ceiling height is supported estimate the doorway width by performing linear interpolation between the two existing doorway widths using the following formula W WI W2 W1 H H1 H2 H1 Where W is the width of the doorway supported for your ceiling h2.
