Consider how many cameras you may eventually install from this wired location and choose a switch with enough POE ports. If you start with a 4 port POE switch you will likely find you have to chain another one to it.
I have 2 of these working very well. There are cheaper similar units but the maximum wattage output is lower and these seem to have a good reputation. The second one I bought as REFURBISHED for $50. and come from the same supplier via Amazon. BV-Tech 9 Port PoE+ Switch (8 PoE+ Ports | 1 Uplink Port) – 120W – 802.3af/at
