1. A system for automatically determining a camera field of view in a camera network, said system comprising:

  • a plurality of spatially separated cameras,direction sensors associated with said cameras, configured to measure a horizontal camera direction angle with respect to magnetic north for the field of view of said cameras and to generate corresponding direction measurement signals;

    elevation sensors coupled to respective said cameras to measure elevation angles for the field of view with respect to a vertical axis and to generate corresponding elevation measurement signals;

    a controller, linked to said cameras and a plurality of physical condition sensors, for processing said direction and elevation measurement signals to automatically determine the fields of views of said cameras;

    wherein said controller is further configured to determine the amount of horizontal and/or vertical rotation required to bring an event of interest into the field of view of at least one camera based on a comparison of the at least one camera'"'"'s direction and elevation measurements to respective predetermined camera-event horizontal and vertical bearings between at least one camera and said event of interest; and

    a facility map containing location information for each of said plurality of spatially separated cameras wherein said facility map is rendered on a graphical user interface display linked to said controllers.
