Abstract
A surveillance camera capable of adjusting a position thereof, and a controlling method thereof are disclosed. The surveillance camera capable of adjusting a position to photograph or capture video images of a monitored area by adaptively driving a camera part in accordance with a predetermined monitoring mode selected by an external controller, includes a pan sensor detecting a standard position of a pan motor that transversely rotates the camera part; a tilt sensor detecting a standard position of a tilt motor that perpendicularly rotates the camera part; and a control part outputting a driving control signal for driving the pan motor and/or the tilt motor, adaptively, according to the received monitoring mode selecting signal, such that standard positions of the pan motor and/or the tilt motor are detected respectively by the pan sensor and/or the tilt sensor by a certain period set according to the monitoring mode. Accordingly, positions of the pan motor and the tilt motor are adaptively initialized during the operation thereof, and therefore, position error caused by loss of driving pulse can be compensated, thereby enabling more correct monitoring work.
