This device is a PoE balun that allows to combine the signal of two cameras to a switch through a single network cable. It is used to place two 10/100 Ethernet circuits on a long-term Ethernet cable with or without a PoE port It supports 2 single data connections 10/100 and up to 30W for each one (60watts in total) in Cat.6 The end is connected to two connectors RJ45 to the switch (A connector in the POE slot and the other to the LAN slot). Using a UTP cable, preferably Cat.6, connects to the other end by transferring data and power. The other end has two RJ45 connectors that can be connected directly to the IP cameras, or if the cameras are separated, connect another RJ45 cable to extend the signal to the cameras a maximum distance of 100m.
