An access control system (ACS) for a building includes an access reader, a camera, and an access controller. The access reader is configured to read an access credential provided by a person at an access point and generate ACS data including the access credential. The camera is configured to capture facial recognition system (FRS) data including an image of the person at the access point. The access controller is configured to determine whether the access credential is valid based on the ACS data, determine whether the person is recognized based on the FRS data, grant or deny access to the person through the access point based on whether the access credential is valid and whether the person is recognized, and generate and store one or more of a plurality of access events. Each of the access events corresponds to a different combination of whether the access credential is valid and whether the person is recognized.
