Description

  The present invention relates to a dome-type surveillance camera, and more particularly to attachment / detachment of a storage medium.

  A conventional monitoring system includes a monitoring camera, a recorder, a cable for transmitting signals and power, and the like, and the video of the monitoring camera is recorded on the recorder through the cable. Therefore, a storage medium is not attached to the surveillance camera, and video is not recorded directly on the storage medium. However, in this configuration, there is a problem that when a malfunction occurs in the recorder, the video of the monitoring camera cannot be recorded on the recorder even if the monitoring camera is operating normally. Therefore, in recent years, a method of attaching a storage medium to the surveillance camera and directly recording the video of the surveillance camera on the storage medium has been increasing.

Among surveillance cameras, the ceiling-mounted dome type surveillance camera has a surveillance camera body, a black design cover to prevent the inside of the dome type surveillance camera from being seen, and cigarette smoke inside the dome type surveillance camera. It is composed of a transparent or smoke type clear dome to prevent dust and dirt from entering, using a metal embedded bracket for mounting the dome type surveillance camera on the ceiling, and a design panel for hiding the embedded bracket Installed. After the dome-type surveillance camera is installed on the ceiling, the number of parts that are exposed to the outside decreases. Therefore, in the dome-type surveillance camera, it is difficult to attach and detach the storage medium directly from the outside after the installation.
For this reason, a storage medium attaching / detaching mechanism is provided at a portion embedded in the ceiling of the dome-type surveillance camera that cannot be directly accessed from the outside, and the storage medium is attached / detached. Needed to remove the dome-type surveillance camera from the bracket.

  Patent Document 1 describes that in a dome-type surveillance camera, an interface of a lighting device can be created on a design panel and the interface can be accessed from the outside. Although not described in Patent Document 1, a method of creating an interface on the design panel and accessing this interface from the outside is also conceivable with regard to the attachment and detachment of the storage medium.

JP-A-2005-347914

  However, as described above, when the illumination device provided on the design panel is changed to a storage medium attaching / detaching mechanism, a cable or a board is required for the interface between the surveillance camera body and the storage medium, which increases the number of parts. There's a problem. Further, assuming work at a high place when the storage medium is attached / detached, work such as cable routing occurs, which makes it difficult to work.

  The present invention has been made to solve the above-described problems, and provides a storage medium attaching / detaching mechanism that allows a storage medium to be attached / detached without removing a dome-type surveillance camera and without performing work such as cable routing. The purpose is to obtain.

A dome-type surveillance camera according to the present invention includes a surveillance camera body that has a control circuit unit and a lens unit to shoot an image, a clear dome that is detachably attached so as to cover the lens unit, a control circuit unit, and an electrical circuit And a storage medium attaching / detaching mechanism that moves horizontally in conjunction with the lens unit, is located on the side of the lens unit, and has a storage medium attachment / detachment opening directed toward the clear dome.

  According to the present invention, the clear dome can be removed and the storage medium attachment / detachment port faces the clear dome, so that the work such as cable routing can be performed without removing the dome type surveillance camera. Storage medium can be attached and detached.
