Bought this on here a few months back but have since noticed:

a) It's 24V Passive PoE, so won't work on my 802.11af switch.

b) The coating has become sticky with a yellow-ish tinge with dust stuck to it. Could probably clean it up with the right product - unsure. Will add a photo in the minute

No PoE adapter included, will require a Unifi switch supporting 24V PoE or an injector.

Will ship for $5
