![]() PoE+ switches can power remote pan, tilt, and zoom (PTZ) surveillance cameras, IP phones, alarm systems, and other devices. The ports have a voltage range of 50-57V. PoE+ switches supply up to 30 watts of power per port, about twice the power supplied by the base PoE standard. PoE+ ( IEEE 802.3at) is an enhanced version of PoE that provides higher power delivery capabilities. PoE switches are commonly used for simple devices like VoIP telephones, stationary cameras, sensors, etc. ![]() The standard specifies that PSEs can supply up to 15.4 watts of power per port, while PDs can consume up to 12.95 watts. PoE switches comply with the IEEE 802.3af standard, which specifies the maximum power delivered over Ethernet cables. PSEs are typically network switches or injectors that supply power over Ethernet cables, while PDs are devices that receive power over Ethernet cables.īelow, we explain the distinct characteristics of the various PoE standards. The standard defines two types of devices: power-sourcing equipment (PSE) and powered devices (PDs). The Institute of Electrical and Electronics Engineers Standards Association (IEEE SA) develops the IEEE standards, which provide rules and benchmarks for producing goods in the electronics and technology industry. They are generally classified into three based on the IEEE standards: It is often used as a cost-effective option to set up devices like IP cameras, wireless access points, and Voice over Internet Protocol (VoIP) phones in areas without power outlets.Īs you may already know, there are different types of PoE (switches). This section will provide a brief overview of the three main PoE standards - Type 1, Type 2, and Type 3 - developed by IEEE and explain the key differences between them.Ī PoE switch is a network switch that allows data transmission among devices on a network and also supplies power to them via a single cable to the compatible devices. Power over Ethernet (PoE) is a technology that enables the transmission of electric current and data simultaneously over Ethernet cables, eliminating the need for separate power cables.
