Description: TECHNICAL FIELD The present invention relates to a monitoring camera device for monitoring a wide range outdoors.

〔発明の概要〕[Outline of Invention]

である。
The present invention relates to a surveillance camera device, which is provided with a convex mirror and directs the lens optical axis of the video camera to the spherical center of the convex mirror, thereby enabling a wide range of 360-degree surveillance.

〔従来の技術〕[Conventional technology]

A monitoring device using a video camera has been put into practical use (see Japanese Patent Application No. 60-110566). However, in such a device, it is not easy to monitor the 360-degree range around the monitoring point.

That is, a normal video camera cannot shoot behind the camera, which is a so-called blind spot. Therefore, in order to eliminate such a blind spot, for example, it is conceivable to install a plurality of video cameras so as to face each other in a blind spot direction. However, the provision of a plurality of cameras in this way makes the structure extremely complicated and is not preferable in practice.

On the other hand, by installing it on the turntable of one video camera and rotating this turntable at a predetermined cycle,
It was proposed to get a 0 degree field of view. However, in this case as well, the structure of the rotation mechanism and the like is complicated, and although the blind spot moves with time, it still exists, and it is not possible to constantly monitor 360 degrees around.

Further, as shown in FIG. 3A, a mirror (32) may be provided at an angle of 45 degrees with respect to the lens optical axis of the video camera (31) and the mirror (32) may be rotated about the optical axis. Though conceivable, although the configuration of the rotating mechanism and the like is somewhat simple, the blind spot is not completely eliminated, as in the above example.
It is also proposed to provide a so-called fisheye lens (33) on the lens of the video camera (31) as shown in FIG. 9B, but the field of view of the fisheye lens (33) is generally as shown in the figure, and It cannot do 360 degree surveillance.
