Patent Images
1. A video tripwire system comprising:
- a sensing device producing video output; and
a computer system, including a user interface, for performing calibration and for gathering and processing data based on video output received from the sensing device, the user interface comprising input means and output means, said input means including a graphical user interface, wherein the computer system displays processed data, and wherein said graphical user interface is adapted to enable a user to draw a video tripwire on at least one of a video image of said video output or a snapshot taken from said video output.
