Power over Ethernet (PoE)

Power over Ethernet (PoE) is a technology that simultaneously transmits data and power over existing Ethernet infrastructure. This technology not only transmits network data through a standard Ethernet cable, but also provides DC power to remote devices without the need for additional power cords. The PoE system mainly consists of two parts: power supply equipment (PSE) and power receiving equipment (PD). PSE is responsible for injecting power into Ethernet signals, while PD is responsible for extracting power from Ethernet signals and converting it into the voltage required by the device. In design principle, PoE utilizes Ethernet idle pairs (such as 4, 5, 7, 8) or all four pairs (depending on the standard) to transmit power while keeping network data transmission unaffected.

Power over Ethernet (PoE): Power over Ethernet (PoE) is widely used in various scenarios that require remote power supply and network connectivity. In the field of security monitoring, PoE technology enables devices such as cameras and access control systems to simultaneously transmit data and supply power through a single Ethernet cable, greatly simplifying wiring work and reducing installation costs. In the field of wireless communication, PoE provides power for wireless access points, base stations, and other devices, supporting flexible deployment of wireless networks. In addition, PoE is widely used in smart homes, building automation, industrial Internet of Things and other fields, providing convenient and efficient power solutions for various smart terminals and sensors. By reducing the number of cables, PoE technology also improves the reliability and security of the system.
