<p>A dome camera (1) includes a lens unit (5) having an adjustable lens focal point, a dome cover (4) for covering the lens unit (5), and a pseudo-cover (7) having optically equivalent characteristics to those of the dome cover (4). The pseudo-cover (7) is capable of rotating around a rotation axis which is set at the lens unit (5) from a lens focal point adjusting position which is set on an optical axis of the lens unit (5) toward a retraction position which is back from the optical axis of the lens unit (5). At the time of lens focal point adjustment work, the lens focal point is adjusted while the pseudo-cover (7) is set at the lens focal point adjusting position. When the lens focal point adjustment work ends, the pseudo-cover (7) is rotated to the retraction position to retract from the optical axis of the lens unit (5), and the dome cover (4) is put over the lens unit (5). Thus, there is provided a dome camera capable of improving the workability of the lens focal point adjustment work with a simple and inexpensive configuration.</p> |
