System of visually monitoring and recording of controlled access entry

摘要

An access control system for permitting or denying access to a restricted area includes an access control device capable of reading information stored on an access card and determining whether the information read from the access card corresponds with memory information stored in the access control device to permit or deny access to a restricted area. A video camera is positioned at the entry area to the restricted area to capture live video images of an individual attempting access. The access control device determines whether the card is valid or invalid and translates the information into an output having text information through a serial communications interface port or other means of transmitting data to a text overlay control device. The text overlay control device overlays the text information describing the access control event directly onto the video images received from the video camera. The text information and video images are displayed on a video monitor while also being recorded on a video cassette recorder for later viewing.
