Description of the Related Art A plurality of fixedly mounted surveillance cameras are installed on a ceiling or a wall of a building to photograph a plurality of surveillance points, and the photographed images can be simultaneously monitored in a place separated from the surveillance points. Systems are conventionally known.

In such a monitoring system, a monitoring image of a camera for each monitoring point is displayed on a monitor screen, a monitoring image of a plurality of monitoring points is sequentially displayed on a monitor, or a plurality of (for example, four) monitoring images are displayed. The screen is divided and displayed at the same time to reduce the installation space of the monitor and reduce the monitoring load. Therefore, each camera is assigned an identification number, and display control and recording control of a monitor are performed based on the camera number.

[0004]

However, in the above-described conventional surveillance camera device, it is not only necessary to fix the camera to a ceiling or a wall at the time of installation by using a special mounting bracket, but also to use a power supply for supplying power. It is necessary to lay the wiring and lay a coaxial cable and the like for transmitting the video signal, and the installation cost is high.

Further, if it is necessary to change the layout of the surveillance camera group in response to a change in the layout of the monitored object, it is necessary to reconnect the wiring for supplying power and the video signal transmission cable. Also, the layout change was expensive.

In particular, regarding electric wiring, although electric wiring is usually provided for indoor lighting or the like, the power supplied from the electric wiring may be different from the power used in the surveillance camera. In addition, power cannot be easily supplied to the surveillance camera, and the electric wiring is complicated.

[0007] For these reasons, it has been conventionally difficult to configure a surveillance system with various camera installation modes.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a surveillance camera device that can easily be attached and connected with wires and enables various system configurations.

Wireless communication means for transmitting to the device.

In this surveillance camera device, when the detachable portion of the case is attached to the wiring fixture for lighting installation, external power is supplied to the camera body to obtain monitoring information, and this monitoring information is transmitted to the outside by wireless communication means. Is transmitted to the communication device. Therefore, the installation is as simple as the installation of an electric light, and wiring connection for power supply is not required. In addition, since the monitoring information from the camera is wirelessly transmitted to an external communication device, it is not necessary to lay a signal transmission cable, and it is possible to easily cope not only with the installation of the camera but also with a layout change or the like.

In the surveillance camera device according to the present invention, it is preferable that the wireless communication means has identification information for wireless communication, and functions as a communication terminal in a wireless network based on the identification information. In this case, a monitoring system using a plurality of monitoring camera devices can be easily constructed.

Further, in the surveillance camera device of the present invention, when the identification information is specified to the wireless communication means and a transmission request of the monitoring information is made from a predetermined external communication terminal, the monitoring information is output. It is preferable to provide monitoring control means for operating the camera body. With this configuration,
The monitoring information by the camera body can be appropriately transmitted in response to a transmission request from an external communication terminal.

In the surveillance camera device according to the present invention, it is preferable that a light emitting means for illuminating a vicinity of a monitoring point of the camera body is accommodated in the case. This is because it is possible to reliably illuminate the monitoring target and to make it difficult for the monitoring target to visually recognize the camera.

The identification information for wireless communication is, for example, TCP / IP (Transmission Control Protocol / TCP).
Internet Protocol) own IP in network
Address.
