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 to deploy on the existing LAN infrastructure. Using power injectors, up to 30W of DC power and data coming from a non-PoE switch or router are combined and then transmitted to IEEE 802.3at/af compliant products such as PoE dome cameras via the Ethernet cables. Therefore, preserve your investment in hardware upgrade without having to purchase additional PoE switches. IEEE 802.3at/af Power over Ethernet Standard Due to the addition of IEEE 802.3at/af Power over Ethernet to a non-PoE Ethernet switch or router, the GP-101IT can be directly connected to any IEEE 802.3at/af end nodes such as PTZ (Pan, Tilt, Zoom) network cameras, PTZ speed dome, color touch screen Voice over IP (VoIP) phones and multi-channel wireless LAN access points where the IEEE 802.3at/af in-line Power over Ethernet port is supported. Higher cost-effectiveness and easy installationPower over Ethernet technology enables the Ethernet cable to carry both data and power. Thus, the GP-101IT reduces the need for cable installation and eliminates the need for extension cords or power outlets on the wall, ceiling or any inaccessible place. Overall, it lowers installation costs and simplifies installation work. Flexible and reliable power supplyWith PoE short-circuit protection to protect network devices and protect against damage.
