Wide-area site-based video surveillance system

A method for wide-area site-based surveillance, comprising:

• receiving surveillance data, including view targets, from a plurality of sensors at a site;
• synchronizing said surveillance data to a single time source;
• maintaining a site model of the site, wherein said site model comprises a site map, a human size map, and a sensor network model;
• analyzing said synchronized data using said site model to determine if said view targets represent a same physical object in the site;
• creating a map target corresponding to a physical object in the site, wherein said map target includes at least one view target;
• receiving a user-defined global event of interest, wherein said user-defined global event of interest is based on said site map and based on a set of rules;
• detecting said user-defined global event of interest in real time based on a behavior of said map target;
• and
• responding to said detected event of interest according to a user-defined response to said user-defined global event of interest

A computer-readable medium containing software that, when read by a computer, causes the computer to perform a method for wide-area site-based surveillance, the software comprising:

• a data receiver module, adapted to receive and synchronize surveillance data, including view targets, from a plurality of sensors at a site;
• and
• a data fusion engine, adapted to receive said synchronized data, wherein said data fusion engine comprises:
• a site model manager, adapted to maintain a site model, wherein said site model comprises a site map, a human size map, and a sensor network model;
• a target fusion engine, adapted to analyze said synchronized data using said site model to determine if said view targets represent a same physical object in the site, and create a map target corresponding to a physical object in the site, wherein said map target comprises at least one view target;
• and
• an event detect and response engine, adapted to detect an event of interest based on a behavior of said map target.
