Abstract
A method and apparatus for controlling a panning/tilting motor of a monitoring camera is disclosed. The position or speed of the motor is controlled based on the output of a hall sensor built in the motor without any position detection device such as encoder, so that the closed loop control of the panning/tilting motor is accurately performed, and the position coordinate of the panning/tilting motor is not distorted when the motor is out of step.
