がかったトップカバー１を被せる構造としている。Conventionally, a dome type television camera capable of adjusting the angle of view has a mechanism 4 for horizontally rotating an upper half (a part including a SENS part) of a camera body and a SENS part (a part including an optical lens and an image sensor). A three-dimensionally adjustable angle of view can be achieved by three mechanisms, a vertical rotation mechanism 3 and a horizontal rotation mechanism 2, and further covers the top cover 1 with a clear imaging unit from above the optical lens. The structure is such that the smoked top cover 1 is covered to make it difficult to understand the shooting direction and location.

ラの感度を低下していた。In the case of this conventional example, since there are three rotation mechanisms for adjusting the angle of view, the number of mechanical parts is large, the number of assembly steps is large, and the cost is large. If the top cover 1 is not removed, the angle of view cannot be adjusted at the time of installation.
In order to make it difficult to see the location, the sensitivity of the camera is reduced by putting the smoked top cover 1 on the front surface of the optical lens.

感度が低下するなどの問題点がある。Conventionally, a dome type television camera capable of adjusting the angle of view has a large number of parts due to a complicated rotation mechanism for adjusting the angle of view, is large in cost, is complicated to assemble, and is installed without removing the top cover. The angle of view cannot be adjusted. Also,
There is a problem that the sensitivity of the camera is reduced because the imaging unit covers the smoked top cover in order to make it difficult to specify the shooting direction and location.
