I ran cat-5 from my hp procurve (already in my basement) to an eight-port switch on my shelving rack. If you're running your operation in your detached garage or an outbuilding and you already have 75-ohm (TV) coax ran to the building, then get a set of these DECA Ethernet to Coax adapters http://a.co/gyipPwP. I have a PoE switch in my detached garage with several HD IP cameras and I've never had any issues since I installed these. I formerly used a WiFi bridge and I would run into throughput issues. The DECA units solved that issue. I suppose you could also use the DECA units for interior runs of 75-ohm coax cable in order to have a "hard wire" solution. I've also read good anecdotes about the adapters that make the network go through the power outlets too.
