基于电力线通信的户外视频监控网络改造

摘要

简要介绍了宽带电力线通信技术的特点和典型应用，分析了当前平安城市建设的大背景下传统老旧户外视频监控网络改造的必要性。针对常见电力线调制解调器产品使用中存在的问题和视频监控的户外使用特点，提出了一种低成本但有效的解决方案，不仅解决了低温环境条件下电力线调制解调器产品无法正常工作的缺点，而且简化了操作，提升了用户体验。%The specifications and typical application of broadband power line communication technology is introduced briefly,and the improvement of the old outdoor video surveillance network is necessary under the background of safe city construction.As the usual PLC modem has some inconveniences in configuration,and the video surveillance equipments are often installed outside the building,a low⁃cost but effective solution is proposed in this paper.This solution not only solves the problem that the PLC modem can’ t operate normally in low temperature condition,but also simplifies the operation and promotes user’ s experience.
