Description

  The present invention relates to a security camera system for an elevator provided with a security camera for photographing a state in a car room.

  While elevators are highly public vehicles that can be used by an unspecified number of people, the car interior during driving is in a closed room, which sometimes results in crime. For this reason, there are many elevators in which a security camera is installed in the car room (see, for example, Patent Document 1).

  FIG. 5 is an explanatory diagram showing the configuration of a conventional security camera system for an elevator in which a security camera is similarly installed in the car room, although it is not the system configuration disclosed in Patent Document 1. In this figure, a security camera 2 is installed in the vicinity of the ceiling in the room of the car 1 on which the user M1 is riding. The appearance of the user M1 is photographed by the security camera 2, and the image data is sent to the image processing device 3 for image processing. The signal image-processed by the image processing device 3 is sent via the cable 4 to the monitor device 6 in the monitoring room 5 where the supervisor M2 is present and displayed on the screen.

  The monitor M2 can monitor the state of the user M1 in the car 1 through the screen of the monitor device 6. If the user M1 shows suspicious behavior, the monitor M2 is provided on the operation panel OP. Necessary measures can be taken, such as interacting with the user M1 through a speaker and a microphone.

Further, the image data obtained by photographing with the security camera 2 is normally stored in a recording medium in the image processing device 3 until a predetermined period elapses. Therefore, when a criminal case or the like occurs in the car 1 or in the building, the recorded image data may become a powerful investigation material or evidence material at a later date.
