Description

  The present invention relates to a surveillance camera that is installed on a ceiling or the like for crime prevention.

Conventionally, surveillance cameras that have built-in imaging means (for example, CCD or C-MOS cameras) to capture and monitor a person are widely used in public facilities that require strict security such as financial institutions, companies, and museums. However, in recent years, it has been installed not only in such facilities but also in ordinary households (particularly apartments).
And in installation of such a surveillance camera, for example, as disclosed in Patent Document 1, a fixed bracket and a movable bracket (horizontal or vertical) for adjusting the angle of view of the camera are used to mount the ceiling or wall surface.
