Abstract
An occupant detection device may be configured to detect an occupant in a space where the occupant detection device is installed. The occupant detection device may include an occupant detection circuit that is configured to determine locations of one or more occupants in the space. The occupant detection device may also include a low-power detection circuit that is configured to indicate an occupancy or vacancy condition in the space. The occupant detection device may include a control circuit that is configured to determine that the low-power detection circuit indicates that there are no occupants within the space. The control circuit may determine that there is movement in an occupant map or a region of interest (ROI) as indicated by the locations of the one or occupants as determined by the occupant detection circuit. The control circuit may configure masked regions around the locations of the movement, and store the masked regions in memory. The movement detected by the occupant detection device within the masked regions may be ignored when determining an occupant count for the space.
