I'm very happy with my POE injector, but it's not powerful enough to support AT. I had this connected to my Meraki MR52 which requires an AT PoE injector or connection to a PoE switch and I was seeing weak signals on the dash. Replaced it with another PoE injector which turned out to be a bit more powerful and works great now. If you want to power a camera like the Meraki MV12, this is a great solution.
