System and method for monitoring opening or closing of doors of an area of interest

Abstract

A system to detect movement of doors associated with an area of interest (AOI) is disclosed. The system comprises a pressure sensor positioned at a predefined position within the AOI, wherein the pressure sensor is operable to monitor air pressure within the AOI, and a processing device in communication with the pressure sensor. The processing device comprises one or more processors coupled to a memory storing instructions executable by the processors, and configured to monitor, using the pressure sensor, the air pressure within the AOI in real-time, detect and measure a change in the air pressure within the AOI based on the monitored air pressure, and detect opening or closing of one or more doors associated with the AOI based on the measured change in the air pressure within the AOI.

Dependencies are inferred from the claim text.
