A surveillance camera comprising an image capturing portion having a rotational drive portion for rotatingly driving an image capturing lens about a pan axis and an initial position sensor providing a reference to the pan angle of the image capturing lens, a base for the image capturing portion to be attached thereto with the pan axis positioned toward a changeable direction, a controller electrically connected to the drive portion and the initial position sensor, and restrictive portion for mechanically restricting the permissible pan angle of the image capturing lens to different angles in accordance with the direction of the image capturing portion as attached to the base. The controller detects the direction of the image capturing portion as attached to the base based on the angle of rotation of the drive portion and the position of the initial position sensor. |
