特開２０１３−１８７７２５号公報JP 2013-187725 A

上記したように、監視カメラの撮像映像を汎用通信ネットワークを介して配置された映像保存手段に録画する場合、監視カメラをＬＡＮに接続し、ＨＵＢやルータを介して汎用通信ネットワークに接続しなければならなかった。特に土木工事現場や建設現場のような日々環境が変化する場所では、不審者は比較的侵入し易いにも関わらず、監視カメラの設置はその電源の確保や通信線の配線等が厄介であり簡単ではなかった。   As described above, when recording a captured image of a monitoring camera on video storage means arranged via a general-purpose communication network, the monitoring camera must be connected to the LAN and not connected to the general-purpose communication network via a HUB or a router. did not become. 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.

そこで、面倒な設置作業を改善するために、監視カメラを無線化することが考えられる。無線化すれば、汎用通信ネットワークとの接続においてＨＵＢやルータを介する必要がないため作業の簡略化がきる。しかしながら、無線機能を加えることで監視カメラが大型なものとなり、その取り付け自体が簡単ではなくなるし、設置場所も制限される。   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, by adding a wireless function, the surveillance camera becomes large, and the installation itself is not easy, and the installation location is limited.

本発明はこのような問題点に鑑み、複数の監視カメラを設置しても汎用通信ネットワークとの接続が容易な監視カメラシステムを提供することを目的としている。   The present invention has been made in view of such problems, and an object of the present invention is to provide a surveillance camera system that can be easily connected to a general-purpose communication network even if a plurality of surveillance cameras are installed.

上記課題を解決する為に、請求項１の発明は、複数の監視カメラと、汎用通信ネットワークを介して監視カメラの撮像映像を保存する映像保存手段とを有する監視カメラシステムであって、複数の監視カメラは、汎用通信ネットワークを介して映像保存手段と通信を実施する共通の映像送信装置にＬＡＮケーブルを介して接続され、映像送信装置は、ＬＡＮケーブルを介して各監視カメラに電源を供給する電源供給手段を有することを特徴とする。   In order to solve the above problems, the invention of claim 1 is a surveillance camera system comprising a plurality of surveillance cameras and video storage means for storing captured images of the surveillance cameras via a general-purpose communication network. The surveillance camera is connected via a LAN cable to a common video transmission device that communicates with the video storage means via a general-purpose communication network, and the video transmission device supplies power to each surveillance camera via the LAN cable. It has a power supply means.

本発明によれば、複数の監視カメラを設置しても、汎用通信ネットワークとの接続は映像送信装置１台で済むため、監視カメラ毎に汎用通信ネットワークに接続する必要がない。よって、ハブやルータを配設する必要が無く簡易な作業で設置できる。そして、映像送信装置にＬＡＮ接続すれば、電源が映像送信装置から供給されるため、電源配線も必要ない。更に、使用する回線数は監視カメラの台数分必要無く１回線で済み通信費用を削減できる。   According to the present invention, even if a plurality of surveillance cameras are installed, the connection to the general-purpose communication network is only one video transmission device, and therefore it is not necessary to connect each surveillance camera to the general-purpose communication network. Therefore, it is not necessary to provide a hub or router, and it can be installed with simple work. Then, if a LAN connection is made to the video transmission device, power is supplied from the video transmission device, so that no power wiring is required. Furthermore, the number of lines to be used is not required for the number of surveillance cameras, and only one line can be used, thereby reducing communication costs.
