1. A computer-implemented method carried out within a physical access control system, the computer-implemented method comprising:
activating at least one non-imaging sensor to capture non-imaging data, the non-imaging sensor monitoring an area in respect of which the physical access control system restricts access;
employing at least one processor to generate a count of people present in the monitored area from computerized analysis of the non-imaging data; and
generating an unauthorized person alert based on at least one of a plurality of alert conditions being satisfied, the plurality of alert conditions including:
a first condition that the count of the people exceeds a maximum count for the monitored area, and
a second condition that the count of the people exceeds a reduced maximum count for the monitored area, wherein a determination of the reduced maximum count is reached at least in part by subtracting a number of one or more system-authorized people from the maximum count based on one or more tracked locations, of the respective one or more system-authorized people, being outside of the monitored area.
