Reservoir Video Surveillance Dual-Link Backup Networking Solution
Video surveillance of reservoirs on China Hainan Island utilizes a comprehensive network connecting cameras across the province through a dedicated optical fiber network provided by the carrier. However, due to frequent typhoons in Hainan Province, the wired optical fiber may be damaged, resulting in network failures for reservoir video surveillance. This could impact the disaster prevention and mitigation center's ability to assess disasters accurately.
The system consists of three main components: front-end devices, transmission equipment, and central platform. The front-end devices include network cameras and switches, with the ability to connect multiple cameras to a single switch. The transmission equipment employs Xiamen Four-Faith industrial-grade routers to ensure stable and reliable data transmission. The central platform performs real-time monitoring of video feeds from various reservoirs across the entire province.
