When I installed my system, I already had an 8 port GB switch on hand. I just needed poe. Check out this website with injector blocks. http://wifiqos.com They sell thru ebay and amazon. It makes for a clean install in a structured wiring can. I have dual NIC's on my pc nvr so I can run my cameras on a separate network from my computers, it worked out well to mount the small switch and poe block together. I have no interest in this company other than purchasing their products.
