Abstract
A method and system for controlling a passage from a secured location to an unsecured location based on presence detection of the unsecured location, including: a radar system in the secure location configured to transmit radar signals to and receive radar signals from the unsecured location; on determination of the presence, by the radar system, of a first person in the unsecured location proximate to the passage, providing an alert. The determination of the presence of the first person in the unsecured location may be triggered by a second person in the secured location moving proximate to the exit or by the second person in the secured location requesting to exit through the passage.
