Fengrunda, Henan Eyalet Hükümeti için istikrarlı yüksek çözünürlüklü uzun mesafeli kablosuz gözetim sağlıyor

1. Background of the project

This project is a wireless monitoring project of the Henan Provincial Government. The Henan Provincial Government is the national administrative agency of Henan Province . It is located on Weier Road, Jinshui District, Zhengzhou City. In order to better protect the safety of people’s lives and property, it decided to install a monitoring system around the provincial government building.

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 around the provincial government;

2、İletim görüntüsünün net bir şekilde görülebilmesini sağlamak için eş kanal veya diğer parazit kaynaklarını etkili bir şekilde önleyin;

3、It facilitates wiring and installation, shortens the project construction period as much as possible, and improves safety warning;

4、Effectively resist the invasion of outdoor bad weather and ensure stable and smooth network transmission;

5、Facilitates 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 the RD-W353CPE outdoor wireless bridge as the transmission backbone equipment in the wireless transmission network. The bridge is waterproof, sunproof, and lightning-proof. It has a built-in 12dBi gain antenna, a wireless rate of 300Mbps, and a transmission distance of 1 to 3 kilometers. It has built-in modules and does not require cumbersome power wiring.

According to the monitoring scope and distribution of monitoring points, a total of 14 pairs of RD-W353CPE network bridges are used and installed at various channels and entrances around the provincial government. The longest transmission distance is 1 km. In a one-to-one manner, one One station receives the video signal from the surveillance camera, and the other station sends the video signal to the monitoring center.

Managers can monitor the conditions of the roads surrounding the provincial government in real time through the display screen of the monitoring center.

4. On – site installation of equipment

İnşaat işçilerinin ön uçta güvenlik kameraları ve verici kablosuz köprüleri kurması, ardından arka uç izleme merkezinde alıcı kablosuz köprüyü kurması, NVR ve monitörleri bağlaması ve tüm sistemin donanım kurulumunu tamamlaması gerekir.

Tüm sistemin kurulumu çok basittir ve çok fazla insan gücü, malzeme kaynağı ve zaman maliyetinden tasarruf sağlar. Arka uç izleme odasındaki her bir görüntü planlama kanalının kontrolü çok basittir ve bu da optimize edilmiş yönetim için elverişlidir.

Kurulum sırasında, verici ile alıcı arasında büyük bir engel olmaması için izleme merkezinin konumunun belirlenmesine dikkat edilmesi gerekir. Kurulum tamamlandıktan sonra, geçerli bir IP adresinin yapılandırılması ve kalibre edilmesi ve hata ayıklanması gerekir.
