The invention provides a camera system, including: a supporting base; a rotary driving module for outputting rotary power, including a first driving unit and a driving shaft connected to an output of the first driving unit for being driven by the first driving unit; a camera module, connected to the driving shaft for being driven by the driving shaft to rotate around a central axis of the driving shaft; a mobile driving module including a second driving unit and a driving member connected to the second driving unit. The supporting base is connected to the driving member away from an end part of the camera module. The second driving unit drives the driving member to move, so that the driving member drives the supporting base, the rotary driving module, and the camera module to reciprocate in a direction parallel to the central axis of the driving shaft.
