  As described above, when the captured video of the surveillance camera is transmitted via the general-purpose communication network and recorded on the video recording device, the surveillance camera must be connected to the general-purpose communication network via a HUB or a router. And connection work was troublesome. Especially in places where the environment changes every day, such as civil engineering and construction sites, suspicious people are relatively easy to invade, but the installation of surveillance cameras is troublesome in securing the power supply and wiring of communication lines. It was not easy.

  Therefore, in order to improve troublesome installation work, it is conceivable to make the surveillance camera wireless. If it is wireless, it is not necessary to use a HUB or a router for connection to a general-purpose communication network, so the work can be simplified. However, adding a wireless function increases the size and weight of the surveillance camera, which makes it difficult to install and limits the installation location.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a surveillance camera system that can simplify installation work by making a surveillance camera wireless, and that allows easy installation of the surveillance camera.

In order to solve the above-mentioned problems, the invention of claim 1 is a surveillance camera system in which a surveillance camera device and a video storage means for storing a captured video of the surveillance camera device are connected via a general-purpose communication network. The surveillance camera device includes a wireless communication unit that is wirelessly connected to a general-purpose communication network, and the surveillance camera unit provided with the camera and the wireless communication unit are formed to be separable.
According to this configuration, the wireless communication unit can be installed indoors even if the surveillance camera unit is installed outdoors, and the surveillance camera unit itself can be reduced in size and easily installed. In addition, since the wireless communication unit does not need to be installed outdoors, it is not necessary to take measures against rainwater, and the cost can be reduced.

According to a second aspect of the present invention, in the configuration of the first aspect, the separated monitoring camera unit and the wireless communication unit are connected by a LAN cable, and the wireless communication unit supplies power to the monitoring camera unit via the LAN cable. Power supply means for supplying is provided.
According to this configuration, the LAN cable is simply disposed between the monitoring camera unit and the wireless communication unit, and the monitoring camera unit is activated and the captured video is transmitted. You can connect both.

  According to the present invention, it is possible to install the wireless communication unit indoors even if the surveillance camera unit is installed outdoors, and the surveillance camera unit itself can be made small and easy to install. In addition, since the wireless communication unit does not need to be installed outdoors, it is not necessary to take measures against rainwater, and the cost can be reduced.

It is a block diagram which shows an example of the surveillance camera system which concerns on this invention. It is a circuit block diagram of a surveillance camera device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing an example of a surveillance camera system according to the present invention, wherein 1 is a surveillance camera device, 2 is a server as a video storage means, and the surveillance camera device 1 and server 2 are the Internet and a cellular phone network. Or the like via a general-purpose communication network N.
Note that the video storage means may not be a server, but may be a recording device dedicated to a monitoring camera such as NVR.

  The monitoring camera device 1 includes a monitoring camera unit 1a and a wireless communication unit 1b, which are connected by a LAN cable L1. However, although the monitoring camera unit 1a and the wireless communication unit 1b are shown as separate bodies in FIG. 1, they are structured so that they can be connected together. In that case, the LAN cable L1 is accommodated in an accommodating portion (not shown) provided between them.

   FIG. 2 is a circuit block diagram of the monitoring camera device 1. As shown in FIG. 2, the monitoring camera unit 1a includes a camera 11 having an image sensor, a video signal processing unit 12 that processes a video signal, a monitoring camera CPU 13 that controls each unit of the monitoring camera unit 1a, and a monitoring camera unit 1a. A power supply unit 14 that generates drive power, a PoE power reception unit 15 that supplies power to the power supply unit 14, a monitoring camera IF 16 that communicates with the wireless communication unit 1b, and the like are provided. PoE is an abbreviation for Power over Ethernet (registered trademark), and power is supplied from the wireless communication unit 1b to the power supply unit 14 via the LAN cable L1.

  The wireless communication unit 1b is connected to a wireless communication IF 17 that wirelessly transmits video data to the server 2 via the general-purpose communication network N, a memory 18 that stores a server address and the like, a commercial power supply, and power to each circuit of the wireless communication unit 1b.
