Surveillance systems and methods to monitor, recognize, track objects and unusual activities in real time within user defined boundaries in an area

A surveillance system and method that utilize computer vision technology and background subtraction to monitor, recognize, and track objects or unusual activities within user specified boundaries. The system and method comprises at least one camera and at least one computer with a software program showing one or multiple windows of camera's field of views in real time. The program allows users to define one or multiple boundaries within any window. The program further utilizes background subtraction technique to establish normal "home-position" of objects within defined boundaries. The program compares current image of the objects against the normal "home-position" to determine/calculate the difference of pixel intensity values. If the difference is beyond the predetermine threshold, the program will flag the movement of the object and give off alert.
