One example of a video monitoring system includes a frame acquisition subsystem, a stage gate motion detection subsystem, a person detection subsystem, a face recognition subsystem, and an alert emission subsystem. The frame acquisition subsystem extracts frames from an input video. The stage gate motion detection subsystem separates background motion from foreground motion within frames. The person detection subsystem detects people including faces and bodies within the foreground motion. The face recognition subsystem matches detected faces to previously registered users. The alert emission subsystem provides alerts based on events detected by the stage gate motion subsystem, the person detection subsystem, and the face recognition subsystem.
