What is a POE power supply?

PoE is a wired Ethernet power supply technology. The network cable used for data transmission has the ability of DC power supply at the same time, which effectively solves the centralized power supply of end points such as IP phones, drahtlose APs, portable device chargers, credit card machines, cameras, and data collection. PoE power supply has the advantages of reliability, simple connection, and unified standards: Reliable: A PoE device can supply power to multiple end point devices at the same time, and can also perform power backup while achieving centralized power supply.
