Abstract: A system and method of tracking an object as it navigates through a monitored region is provided. The method includes displaying at least a first video data stream associated with at least a first data collection device monitoring a first region, selecting a linked area of the first video data stream, and displaying at least a second video data stream associated with a second data collection device. The linked area is associated with at least a second data collection device monitoring the second region, and the data collection devices can include PTZ cameras. In some embodiments, the method includes comparing the selected linked area with a stored predefined area using an image recognition algorithm.

Abstract: An object can be specified using active contour modeling. That representation can be stored. A sequence of images can be automatically reviewed to determine if the object can, in some form or state, be detected in one or more of the images. One or more alarms can generated in response to determining the presence or absence of the object from the sequence of images.
