Power over Ethernet is a technology that allows electrical power to be transmitted over an Ethernet network cable alongside data. This eliminates the need for separate power cables for devices such as IP cameras, VoIP phones, and some types of sensors. PoE simplifies installations, reduces cable clutter, and provides a centralized power source.
Long-Range PoE refers to the ability to deliver power and data over extended distances, typically beyond the standard range of traditional PoE deployments. This capability is especially important in applications where devices are located far from the network switch or power source.
