Video Motion Detection Method and Alert Management
First Claim
1. A method of security monitoring with a video camera apparatus where a user observes a video of the detection of object(s) of interest, provides feedback to the camera based on said observations and as a result, improves the accuracy or reliability of future detections of object(s) of interest.

Abstract
This invention describes a method and apparatus for security monitoring with a video camera. A mathematical model consisting of an array of cells, or learning map, is used to describe the motion of any object(s) detected by the camera. When an object(s) is detected, its positional location(s) for a period of time, or motion event, is recorded in a learning map. This learning map is then compared to a reference learning map where the camera determines whether to alert the user or not that an object of interest was detected. After viewing the video of the motion event, the user provides feedback that impacts how the reference learning map is updated by information in the motion event learning map. Through this user feedback mechanism, the camera learns to more accurately determine whether or not to alert the user about future motion events, thus reducing the number of false alarms.

19. A method for managing motion event notifications and alerts with said security camera comprising the following steps of:
-
detecting the presence of object(s); recording presence and motion of said object(s) for a period of time or motion event; characterizing said object(s) presence and motion(s) in said motion event; determining if the user is required to further characterize said object(s) in said motion event; creating a notification of said motion event, if required; assigning a priority to said notification based on characterizations of object(s) in said motion event, if required; sending message to the user if no other outstanding messages are present if required; and placing said notification in a queue based on its assigned priority if required. - View Dependent Claims (20)
