根据实际的监控需求，网络摄像机1的数量可以为多个，即包括多个网络摄像机1，参见图3，图3为网络摄像机1的数量为多个时的电力载波通信网络监控系统的结构示意图。
由于网络摄像机1的数量为多个，为了使每个网络摄像机1均可以基于电力载波的方式通过低压电源线2传输网络数据至网络硬盘录像机3，将每个网络摄像机1的第一电力载波电路11分别与低压电源线2的一端连接。由此，每个网络摄像机1均可通过低压电源线2传输网络数据至网络硬盘录像机3。

电源90将交流电(电能)传输至电源适配器35，电源适配器35将接收到的交流电转换为直流电并传输至电压转换器36，电压转换器36将接收到的直流电的电压转换为网络摄像机1以及自身所需要的电压，并将转换后的电压发送至第二电源电路33，第二电源电路33将接收到的电压通过低压电源线2输出至网络摄像机1以给网络摄像机1供电。
第二电源电路33将接收到的电压发送至第二处理电路34以对第二处理电路34供电。
第二处理电路34发送控制信号至第二网络电路32，以使第二网络电路32发送网络数据至第二电力载波电路31。

为了更清晰的获知本申请实施方案与现有技术的区别，请参见图6，图6为本申请实施方案所提供的一种电力载波通信网络监控系统的结构示意图，由图6可见，网络硬盘录像机3与网络摄像机1之间只通过低压电源线2连接，通过该低压电源线2既传输网络数据又传输电能，相较于图1所示的传统网络监控系统，省去了网线的布置，减少了网络监控系统的成本。
以上所述仅为本申请的较佳实施例而已，并非用于限定本申请的保护范围。凡在本申请的精神和原则之内所作的任何修改、等同替换、改进等，均包含在本申请的保护范围内。
