Supply power over an ethernet cable using POE ("power over ethernet") technology. This is ideal for providing power to security cameras which may not be near a power source. This can be done with a POE switch (pictured), or a POE injector. If the camera or device does not support POE then an active POE splitter is required at the destination end of the cable to separate the data from the power, and to reduce the voltage to an appropriate level for the device.   thesource (378)

Run TWO ethernet signals over a single ethernet cable by using splitters (pictured). This can be preferable to running an extra cable, however this is only possible when you are not using Gigabit ethernet speeds. Slower speeds, such as 100Mbps, which is fast enough for most purposes, use only four of the eight wires in the cable. Splitters divide the cable into two lots of four, enabling you to use all eight wires for two separate ethernet signals. You will need a splitter on each end of the cable.   thesource (378)
