1. Project background
This project is a wireless monitoring project in Beijing Shidu Scenic Area.
Shidu Scenic Area is located in the southwest of Fangshan District, Beijing. It is the only large-scale karst landform in northern China. Shidu Scenic Area is a national AAAA scenic spot in China and a national geological park in China. On September 17, 2006 , UNESCO officially approved and awarded China Fangshan Global Geopark. The successful application of the park has added a scientific and technological global geopark focusing on natural landscapes to Beijing, making Beijing the first capital city in the world to have a “global geopark”. There are eight parks in Fangshan Global Geopark, of which Shidu is the core park of the eight parks – Shidu Park. In order to better manage the scenic area and ensure the safety of tourists, it was decided to install a wireless monitoring system in the Shidu Scenic Area.
According to the actual environment, it was decided to use a wireless video surveillance system to seamlessly build on the original transmission system and ensure economical, convenient construction and beautiful appearance. In this project, Fengrunda mainly serves as the transmission equipment provider for the wireless monitoring system, providing high-quality and high-performance wireless bridge equipment to ensure the smooth completion of the wireless monitoring system.
2. Project requirements
In order to build a wireless monitoring system with clear pictures, high early warning, strong controllability, and convenient timely command and dispatch, the following requirements must be met:
1. Ensure that the network is connected to monitoring points distributed in various areas to conduct real-time monitoring of various areas in and around Shidu Scenic Area;
2. Effectively avoid co-channel or other interference sources to ensure that the transmission picture is clearly visible;
3. Facilitate wiring and installation, shorten the project construction period as much as possible, and improve safety warning;
4. Effectively resist the invasion of severe outdoor weather and ensure stable and smooth network transmission;
5. Facilitate later expansion, maintenance and management of the system;
3. Scheme design
According to customer needs, to ensure clear monitoring images and stable transmission, Fengrunda decided to use RD-S400CPE outdoor wireless bridge as the transmission backbone equipment in the wireless transmission network. The bridge is waterproof, sunproof, and lightning-proof, and has built-in modules, eliminating the need for cumbersome power wiring.
According to the monitoring scope and distribution of monitoring points, a total of 40 pairs of RD-S400CPE network bridges are used and installed in various areas around the Shidu Scenic Area. In a one-to-one manner, one bridge receives the video signal from the surveillance camera. , and the other one sends the video signal to the monitoring center.
Managers can monitor the conditions inside and around Shidu Scenic Area in real time through the display screen of the monitoring center to ensure safe and orderly management of the scenic area.

4. On – site installation of equipment
工事作業員は、フロントエンドに監視カメラと送信ワイヤレス・ブリッジを設置し、バックエンドのモニタリング・センターに受信ワイヤレス・ブリッジを設置し、NVRとモニターを接続し、システム全体のハードウェア設置を完了する必要がある。
システム全体のインストールは非常に簡単で、多くの人手、材料資源、時間コストを節約できます。バックエンドの監視室での各チャンネルの画像スケジューリング制御は非常にシンプルで、最適化された管理に役立ちます。
設置の際には、トランスミッターとレシーバーの間に大きな障害物がないように、モニタリングセンターの位置を決めることに注意を払う必要がある。設置完了後、有効なIPアドレスを設定し、校正とデバッグを行う必要があります。
