The TL-POE200 is designed to deliver power & data over a single Ethernet cable to an Ethernet enabled device up to 100m away. The Po E kit uses two devices, one, the 'injector' injects power & data into a single Ethernet cable while the other, the 'splitter' placed at the receiving end splits the power & data back into two cables to be used by the connected Ethernet device. This convenience allows users to place Ethernet enabled devices such as access points, IP cameras, or Vo IP phones anywhere that they are best suited, regardless of whether a power socket is available, to achieve the best performance for the connected devices. Carries power & data over a single Ethernet cable up to 100 meters away 12/9/5VDC triple output adapts to different Ethernet-enabled devices Hassle free setup, no configuration required Please note: networking components such as switches, routers, UPS & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
