The system enables a user to define a portal, such as doorway of the room. The system then monitors the movement of foreground objects in the room. Objects that appear only in the portal are classified as passing by the portal, e.g., doorway. Objects that initially appear in the portal and then are detected moving within the room are classified as having entered the room. Objects that are in the room and then disappear within the portal are classified as having exited the room. The system further has provisions for generating real-time alerts and performing forensic searches."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for monitoring portal to detect entry and exit","description":"A video monitoring and analysis system detect subjects when they are entering and/or exiting from a room.
