A housing of a rotation type camera apparatus has a standing installation surface for standing installation and a wall-mounting installation surface for wall-mounting installation. The housing is also provided with a dome type cover composing a shooting window facing in a slanting direction with respect to a horizontal direction in a standing-mounting position and in a wall-mounting position. A camera is provided so as to be able to shoot outside from the shooting window. A camera rotation device is accommodated in the dome and has a pan rotation axis based on the horizontal direction. The shooting window faces in an appropriate direction in both the standing-mounting position and the wall-mounting position. Since the pan rotation axis is set based on the horizontal direction, a viewer's eyes do not run up and down so much during the pan rotation.
