一个交换机能带动多少个网络监控摄像头？千兆交换机一般接200万网络摄像机几个？24个网络头，用一台24口百兆交换机行不行？今天我们就这些问题，来系统深入地了解一下。根据摄像机的码流和数量来选择摄像机码流选择交换机前，首先要弄清楚每路图像占用多少带宽。摄像机数量要弄清楚交换机的带宽容量。常用交换机有百兆交换机、千兆交换机。它们的实际带宽一般只有理论值的60~70%，所以它们端口的可利用带宽大致是60Mbps或600Mbps。

家庭配电各个配电回路根据大概负载容量加30％以上来选择导线是安全节能的，即是说；比喻该回路的负载容量大概是2000瓦的话、那就就按照2600瓦以上来选择铜芯导线。下面我列出家庭配电常用的各种规格铜芯导线的安全负载容量供大家参考；（註明；前面的数字是铜芯导线的截面积“平方毫米”、后面的数字是可负载功率“千瓦”）1平方毫米=1.3千瓦左右。5平方毫米=2千瓦左右。5平方毫米=3.5千瓦左右。4平方毫米=5.5千瓦左右。

The mine communication cable has the characteristics of fire prevention, damp proof and so on. The reason of fire is mainly caused by overloading, short circuit, excessive resistance and external heat source. Under the fault conditions such as short circuit, local overheating and external heat, the insulation resistance of insulating materials decreases, the insulation capacity is lost, and even the fire is caused.
