What Is POE
What Is POE? (Power Over Ethernet)Power over Ethernet (PoE) is technology that passes electric power over twisted-pair Ethernet cable to powered devices (PD), such as wireless access points, IP cameras, and VoIP phones, in addition to the data that cable usually carries. It enables one RJ45 cable to provide both data connection and electric power to PDs instead of having a separate cable for each.Power over Ethernet (POE) is a technology that lets network cables carry electrical power.The main advantage of Power over Ethernet (PoE) is delivery of data AND power over one Cat5e/Cat6 Ethernet cable. POE ends the need for AC/DC power supplies and outlets. A remote installation costs less than fiber, as no electrician is needed. Ethernet cable costs less and is often already installed in buildings.For example, a digital security camera usually requires two connections to be made when it is installed.1.A network connection, in order to be able to communicate with video recording and display equipment2.A power connection, to deliver the electrical power the camera needs to operateHowever, if the camera is POE enabled, only the network connection needs to be made, as it will get its electrical power from this cable as well as the network data. Why Use POE? Specifying Power Over Ethernet brings many advantages to an installation: Time and cost savings – by reducing the time and expense of having electrical power cabling installed. Network cables do not require a qualified electrician to fit them, and can be located anywhere….
