The Edimax GP-101IT is a Power over Ethernet injector that not only delivers a cost-effective solution for power distribution but also provides a seamless way of deployment on the existing LAN infrastructure. With the use of power injectors, DC power of up to 30W and the data that comes from a non-PoE switch or router are merged together and then transmitted to the IEEE 802.3at/af compliant products. For example, this can be done for PoE dome cameras through the Ethernet cabling. This preserves your investment without wasting money on hardware upgrades and without the need for buying extra PoE switches.
