Abstract
Provided is a monitoring system and a method of controlling a panning-tilt zoom (PTZ) camera by using a fisheye camera when the fisheye camera and the PTZ camera are adjacently installed. The method includes selecting a region of interest (ROI) in an entire surveillance-target area image captured by the fisheye camera and adjusting a panning angle P and a tilting angle T of the PTZ camera to acquire an accurate image of the selected ROI.
