Abstract:
A method of rotating a surveillance camera having an acceleration sensor and being controllable by a processor to maintain a tilt-angle to conform to a command tilt-angle, includes the steps of moving the surveillance camera tilt to a predetermined command tilt-angle in response to a signal from the processor; periodically calculating estimated tilt-angles by using acceleration values in at least one axis of an acceleration sensor; calculating a difference value between an estimated tilt-angle of a current period and an estimated tilt-angle of a previous period; and when the difference value between the estimated tilt-angles exceeds a set limit, moving the camera to another position to correct the tilt angle according to the difference calculate.

Claim (Index 9):
The method of  claim 8 , wherein the photo-interrupt sensor used in step (a) comprises:\n a light-emitting device configured to irradiate light in a first direction; a photo detecting device configured to rotate due to the tilting operation; and a disc located between the light-emitting device and the photo detecting device in the first direction, and comprising first regions configured to transmit light from the light-emitting device and second regions configured to block the light from the light-emitting device, wherein the photo detecting device is configured to output logic high signals and logic low signals to the processor by passing through the first regions and the second regions while rotating due to the tilting operation.
