There is no surveillance camera system optimum for monitoring an important
monitor place by a surveillance camera mainly for crime prevention day
and night without humans in attendance, which can automatically monitor
the place without humans in attendance and, when something suspicious is
found, follow the suspicious without humans in attendance, and accurately
monitor the suspicious at high precision. The present invention provides
a surveillance camera driving method achieving such a system having the
function of obtaining video image signals by two or more surveillance
cameras each having a three-dimensional positioning pan tilt head
function, organically processing the video information, comparing the
processed information with input data of a plane picture or the like or
data of pictures of a front view and a side view or the like, and
determining whether the processed video signal is the same as the input
data or not.
