The invention discloses a rotation camera with a rain shield function. A rain shield board is bent into [-shaped; and is fixed above a camera housing, and is provided with a downward opening; one side, being close to the lens of the camera, of the outer wall of the rain shield board, is provided with a bar-shaped convex check; the bottom end of a motor is fixed on the upper surface of a first substrate; the top end of the motor is provided with a driving shaft; a first gear is fixedly arranged on the driving shaft; a pedestal for accommodating the camera is arranged on a steering base; the camera is arranged in the pedestal; a second gear is fixedly arranged below the steering base; the second gear is meshed with the first gear, and is axially connected with a third substrate; the third substrate is parallel to the first substrate, and is arranged above the first substrate; the third substrate and the first substrate are respectively in perpendicular direction with two relative edges of the second substrate; and a controller is fixed in a square box and is connected with the line of the camera. The rotation camera with a rain shield function is provided with a rain shield function, and can prevent rain wash influencing the resolving ability of the camera in the rainy day.
