In order to address technical pain points such as the inability to transmit real-time video surveillance at port terminals and the need for manual copying when reviewing surveillance videos

as well as the serious issues of screen distortion and lag in existing 5G video transmission

technical research has been conducted on the network architecture of video transmission. This study proposes a new network architecture that uses 5G cameras (including 5G modules) to replace 5G CPE-NVR-switches and customers' existing cameras. The video stream is directly transmitted to the base station through the 5G camera and then transmitted to the video cloud platform through UPF. The experiment shows that it can effectively reduce the packet loss rate and latency of video feedback

and ensure the playback quality of port terminal video surveillance.
