Great now that you have a good PoE switch, get a length of good
cat5e/6, a good varifocal IP poe camera to play with ( many here like the Dahua OEM 4MP 1/1.8" sensor models ) and look for examples of a test rig here on the forum and start experimenting with positions.
You can get cheaper IP PoE cameras for some spots, having at least one good varifocal camera I think is useful
