I have the 18 port version. 16 are 10/100 POE for cameras and two are Gigabit for uplinking to my main managed switch. Being fanless means I can keep it in my office with the rest of the gear without driving me crazy. 10/100 is plenty of bandwidth for a camera and unmanaged is fine since it'll only be hosting cameras and I use my managed switch to put them all on the same VLAN. I looked at a lot of switches and too many only had a small number of POE ports, too little power, noisy fans, or just cost more than I wanted to spend.
