PoE is also referred to simply as Power over Ethernet. It refers to the technology of transmitting power to devices through twisted pair in Ethernet. It does not need to change the existing Ethernet cabling infrastructure, but also transmits data signals for some IP-based terminals. At the same time, it can also provide DC power for such devices. Through this technology, it is possible to supply power to network telephones, wireless base stations, network cameras, hubs, computers, etc., which are inconvenient to install additional power cords.
Compared with traditional switches, PoE switches have the PoE function. Power is supplied directly through the network cable, which greatly simplifies the wiring and reduces costs. It is loved by many people and removes relatively large brands such as Huawei and Cisco. The leading brand of PoE switches is also quite rich. Popular, widely used in the security industry. It can be seen that PoE power supply is developing very rapidly.
Terminal devices such as wireless APs, IP phones, and web cameras are usually numerous in number, have a special location, and are difficult to take power. Their implementation and deployment not only consumes manpower and material resources, increases network construction costs, but also delays construction time. PoE technology eliminates the problem of installing a separate power supply device on each terminal device through a remote power supply method. This eliminates the need to deploy a separate power supply system for the device at the site of use, which greatly reduces the number of wirings for deploying terminal devices. Management costs have promoted the development of related fields and business development.
Simply put, PoE switches can power network cameras, wireless APs, and Internet telephony and other network devices, eliminating the need for complicated power cabling, simplifying construction and making it easy to use.
However, PoE power supply is not 100% useless. When purchasing, it is not only necessary to supply the quantity and power of the power supply equipment, but also the power supply distance must be within 100 meters. If the selected PoE switch has insufficient power, or exceeds 100 meters, Or the poor quality of the network cable will greatly affect the monitoring project.
