Patent ID: 7868911

Claim:
A surveillance apparatus driving a camera part, the surveillance apparatus comprising: a communication interface which receives a monitoring mode signal indicating a monitoring mode; a motor which moves the camera part; a sensor which detects a standard position of the motor to initialize a position of the motor; a control part which: outputs a first control signal rotating the motor to move the camera part for capturing an image of a monitored site according to the monitoring mode; and if a given condition set for the monitoring mode is satisfied while the motor is being rotated by the first control signal for the capturing the image of the monitored site, outputs a second control signal initializing the position of the motor by rotating the motor from an instant position such that the standard position of the motor is detected by the sensor; and a motor driver which moves the motor according to the first control signal and the second control signal, wherein, if the standard position of the motor is detected by the sensor, the control part outputs a third control signal to the motor drive to rotate the motor back to the instant position to continue the capturing the image of the monitored site from the instant position according to the monitoring mode.
