3 网线问题排查

3.1 网线采用的规格问题

我们推荐5类线以上规格的双绞线（即超5类线，6类线都适用），为了保证信号质量最好选择带屏蔽的双绞线

3.2 连接相机的网线长度问题

网线最长不能超过100米（按照国际以太网传输标准），若超过100米，我们建议中间增加交换机中继或者更换光纤的传输方式

3.3 网线质量问题

网线是否存在中间有折断？水晶头连接处是否有线头脱落断裂？

※注意：在出现网络故障时，我们建议在故障点更换一根没问题的网线再试试

3 Check whether network cables are faulty

3.1 Specifications of Network Cables

We recommend twisted pairs with specifications above 5 types of wires (i.e. over 5 types of wires, 6 types of wires are applicable). In order to ensure signal quality, it is best to choose twisted pairs with shielding

3.2 The length of the Network cable connecting the camera is incorrect

The longest network cable cannot exceed 100 meters (according to the international Ethernet transmission standard). If the network cable is longer than 100 meters, you are advised to add a switch trunk or change the optical fiber transmission mode

3.3 Network Cable Quality Problems

Is the network cable broken in the middle? Is the cable head broken off at the crystal head connection?
