Description

  The present invention relates to an imaging device, and in particular, is used as a surveillance camera or a security camera, and a light-transmitting cover is detachably attached to a housing recess of an imaging device housing that houses an imaging unit and a power supply unit. The present invention relates to an imaging apparatus.

  Surveillance cameras (or security cameras) are installed both indoors and outdoors for the purpose of safety measures to prevent accidents and disasters and security measures against illegal intruders. A dome-type surveillance camera is known as a surveillance camera, and this dome-type surveillance camera is generally a camera unit including a camera body and a device for storing the camera unit inside and installing it indoors or outdoors. A housing and a dome cover attached to a window on the camera body side of the device housing are provided. In addition to the camera body, the camera unit includes a control unit that controls the operation of the camera body, a power supply unit that supplies power to the camera body and the control unit, and the like. The dome cover is a hemispherical colorless transparent cover or a colored transparent cover including gray. The dome cover functions as a lens at the time of photographing and has a function like a cover of an apparatus housing that protects the camera unit.

  When newly installing a surveillance camera, or when performing maintenance work or repair work on an already installed surveillance camera, if the operator can confirm the normal operating state of the surveillance camera before and after the installation and work completion, Work efficiency can be improved. For example, after newly installing a surveillance camera, if you try to check the video from the surveillance camera using a remote monitor, if a failure of the power supply unit, inadequate power supply wiring, failure of the camera body itself, etc. occur, Since the power necessary for the operation of the camera body is not supplied, the surveillance camera does not operate normally and cannot be monitored. In such a case, either the new surveillance camera is installed again or the installed surveillance camera is repaired, and the work efficiency is lowered.

  In order to solve such a problem, a surveillance camera has been developed in which an indicator lamp is provided on the side surface or the like outside the dome cover of the apparatus housing. This indicator lamp is set to emit light when the power necessary for the operation of the camera body is normally supplied. The indicator lamp uses a light-emitting diode (LED) that consumes less power and is inexpensive. If this surveillance camera is used, it can be confirmed whether the operation of the surveillance camera is normal on the spot after installation or after maintenance work or repair work is completed, so that work efficiency can be improved. it can.

  However, since the indicator lamp is lit when the surveillance camera is in an operating state, the person to be monitored senses that the surveillance camera is being monitored and is aware of the presence of the surveillance camera. For example, if the monitored person is a trespasser, there is an effect that the trespass can be prevented. The possibility of doing cannot be denied.

  Such a problem can be solved by incorporating an indicator light in the dome cover of the surveillance camera. However, the light from the indicator lamp may be reflected on the inner surface of the dome cover, and the indicator lamp may be reflected in the image of the surveillance camera. In this case, the image becomes unclear. Therefore, it has been necessary to avoid incorporating an indicator lamp in the dome cover in the surveillance camera.

  In the following Patent Document 1, a circuit board on which a processing unit for a signal obtained from a camera head is provided is provided with a status display means capable of selectively controlling the lighting state and extinguishing state of a display device by operating a switch. A status display device for a monitoring dome camera is disclosed. If this status display device is adopted, the operating state of the camera head is confirmed from the lighting state of the display device during installation, maintenance work or repair work of the monitoring dome camera by selecting the display device to be in the lighting state by operating the switch. be able to. On the other hand, by selecting the indicator to be turned off by operating the switch, the person to be monitored is not made aware of the presence of the monitoring dome camera.
