Design of Adaptive Coding Approach to Support Video Streaming for Camera Surveillance Systems

摘要

In this paper, we design a video streaming and image processing server to support remote surveillance monitoring. The camera nodes are based on Raspberry Pi3, and the smartphone can receive video streams from the server. We analyze advantages and shortcomings of popular codecs and configure appropriate parameters of these codecs for surveillance systems. In experimental results, we demonstrate the proposed system can adjust the quality of video streaming automatically when network bandwidth drops suddenly. Once the network bandwidth is restored, the proposed system can also switch the streaming quality to the original one.
