A system is disclosed. The system has a door that selectively opens to allow access to a cavity and selectively closes to block access to the cavity, a lock configured to selectively lock and unlock the door when the door is closed, a camera configured to image a user area adjacent to the door, computing memory having associated therewith code, and a processor communicatively coupled with the computing memory. The system is configured to execute the code and to control the camera to record a first image data of the user area at a first time, store the first image data, control the camera to record a second image data of the user area at a second time, and selectively unlock the door based on comparing the second image data to the first image data.
