PoE（Power over Ethernet）技术，简单来说，就是通过网线来传输电力。它充分利用了现有的以太网基础设施，使得网线不仅能传输数据，还能为IP终端设备（如IP电话、无线接入点AP、IP摄像头等）提供电力支持。这种技术不仅简化了布线过程，还为IP设备的供电带来了极大的便利。PoE，也被称作基于局域网的供电系统（Power ov...
Power over Ethernet 就是POE，是通过双绞线传输网络信号，同时给设备供电用的。至于用多少电，这个要看输入电压、电流：假设输入电压为220V，电流为0.1A，那么 P=UI=220*0.1=22W W=22*24=528W·h=0.528度 24小时开机的话大约耗电量是半度的样子，开一个月大概15度。
PoE(Power over Ethernet)是指通过网线传输电力的一种技术,借助现有以太网通过网线同时为IP终端设备(如:IP电话、AP、IP摄像头等)进行数据传输和供电。 PoE又被称为基于局域网的供电系统(Power over LAN,简称PoL)或有源以太网( Active Ethernet),有时也被简称为以太网供电。 为了规范和促进PoE供电技术的发展,解决...
