A dome type camera (1) comprises a camera (2), a lower case (3) having a first serration (9), an upper case (4), a dome cover (6), and an inner cover (7) having a second serration (20), where the upper case (4) can be attached to the lower case (3) at two steps of attachment positions which are an adjustment position and a locking position. When the attachment position of the upper case (4) is set at the adjustment position, the first serration (9) and the second serration (20) are incompletely engaged with each other, allowing the inner cover (7) to be rotatable with respect to the lower case (3), and when the attachment position of the upper case (4) is set at the locking position, the first serration (9) and the second serration (20) are completely engaged with each other, allowing the inner cover (7) to be fixed to the lower case (3). The orientation of the cover can be easily adjusted after the cover has been attached, and the work efficiency is improved in installation and adjustment works.
