In my opinion this little kit comes under the category “Must Have” if you are serious about networks. Whether you run out of ports on your PoE switch or need to install equipment that natively don’t support PoE this is a true lifesaver. The kit includes two units: an Injector and a Splitter. An Injector inserts current into the unused wires in a standard network cable (pins: 4, 5, 7 and 8 ) allowing the cable between the Injector and the Splitter to transfer power and network signals simultaneously. The maximum distance between the Injector and Splitter can reach 100m/328ft, and it provides three different output voltage options (5V/2A, 9V/1.2A, 12V/1A)to fit various devices. And most importantly; it’s incredibly easy to set it up. I have used it with several devices and have never encountered any problem.
