Abstract

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.

Claims

1. A dome type camera comprising:

a camera for shooting in a shooting direction;

a lower case to be attached with the camera;

an upper case to be attached to the lower case; and

a cover to be held between the upper case and the lower case for covering the camera,

wherein the lower case has a first engaging portion;

wherein the cover has a second engaging portion for engaging with the first engaging portion, and has a window for maintaining a shooting field of view of the camera;

wherein the upper case can be attached to the lower case at two steps of attachment positions which are an adjustment position and a locking position;

wherein when the attachment position of the upper case is at the adjustment position, the first engaging portion of the lower case and the second engaging portion of the cover are incompletely engaged with each other, allowing the cover to be rotatable with respect to the lower case; and

wherein when the attachment position of the upper case is at the locking position, the first engaging portion of the lower case and the second engaging portion of the cover are completely engaged with each other, allowing the cover to be fixed to the lower case.

2. The dome type camera according to claim 1,

wherein the upper case is provided with a locking piece;

wherein the lower case is provided with a two-step locking groove that has two locking step portions in which the locking piece is locked at two steps;

wherein when the locking piece of the upper case is locked in a first locking step portion of the two-step locking groove of the lower case, the attachment position of the upper case is at the adjustment position; and

wherein when the locking piece of the upper case is locked in a second locking step portion of the two-step locking groove of the lower case, the attachment position of the upper case is at the locking position.

3. The dome type camera according to claim 1,

wherein the cover is provided with an elastic portion that biases the cover toward the lower case;

and

wherein when the attachment position of the upper case is at the adjustment position, the first engaging portion of the lower case and the second engaging portion of the cover are incompletely engaged with each other by a biasing force of the elastic portion, allowing the cover to be rotatable with respect to the lower case and, preventing the cover from rotating along with the upper case when the upper case is rotated with respect to the lower case.

4. The dome type camera according to claim 1, having a fixing member for fixing the upper case to the lower case when the attachment position of the upper case is at the locking position.
