Given the price, I was skeptical about the quality of the camera. After plugging it in, I was surprised at how good it is. Chromatic aberrations are there, but certainly not much worse than other cameras even 3 times more expensive. The autofocus works well and seems to track movement quite well. PoE is really just PoE, not PoE+. I haven't seen any mention of PoE+ anywhere, so any injector or switch that supports the PoE standard (802.3af) should work.
