• receiving, at a mobile devices signals from a plurality of access control devices, each access control device including a camera sensor, and each signal comprising an identifier of a sending access control device and a status of a region of interest of the camera sensor of the sending access control device;
• determining that the mobile device comprises a credential that is authorized to unlock the plurality of access control devices;
• determining, based on the signal, whether a person is in the region of interest of the camera sensor of one of the plurality of access control devices and moving towards the one of the plurality of access control devices;
• and
• transmitting a request, to the one of the plurality of access control devices and not to any other of the plurality of access control devices, to unlock the one of the plurality of access control devices based on determining that a person is in the region of interest of the camera sensor of the one of the plurality of access control devices and moving towards the one of the plurality of access control devices, the request including the credential,
• wherein the receiving and transmitting are via a short-range wireless communication interface that is initiated in response to the mobile device being within a transmission range of transceivers on the plurality of access control devices.
