Abstract: A technique for counting occupants is disclosed. An occupancy control apparatus may be part of an access control apparatus or security system to identify a visitor. The number of occupants is calculated from the difference between a value obtained by counting people who have entered and a value obtained by counting people who have left, to control occupancy when the number exceeds a threshold value. An error rate per count in the form of a fraction is calculated for each counter, so that the current counter value can be corrected in real time. When the number of occupants exceeds the threshold value, the entrance may be blocked, and when the number of occupants is restored to less than another threshold value, a blocked state of the entrance may be cancelled. The error rate per count of the counter may be calculated for each apparatus and each time period.
