Power over Ethernet is a technology that allows network cables to carry electrical power. The benefits of PoE offer both improved network efficiency, costs saving and flexibility. For example, a digital security camera normally requires both network cabling and an electrical connection.
Time and cost savings – with the ability to run one ethernet cable to each device a savings is realized by eliminating the need for the labor and material expenses associated with electrical power. Applications across multiple market segments are numerous, including point of sale devices, nurse call systems, digital signage, video conferencing and access control.
PoE promotes network flexibility. Without the need to be reliant upon the location of electrical outlets, devices such as IP cameras and wireless access points can be installed throughout a building or campus environment where needed most. Network adds, moves, and changes can be accomplished faster with PoE-enabled switches and network devices. The business will not be impacted by delays in completing network modifications or upgrades. Additionally, PoE can facilitate temporary network deployments for offices, classrooms and conference rooms by eliminating the need for the installation of additional power to support networking devices.
