Does this 3er set come with a wall power connector/cable and wall mount? I want to connect one NanoHD via ethernet to my Omnia Turris router (which doesn't have PoE). So I would need to plug that that into a wall socket. Does this unit come with the kind of power cable? If I not, which other product do I also need to buy? I would also like to use my other units as APs, so I want to mount them, potentially outside. Does this unit come with what I need to wall/roof mount them? If not, which other product do I also need to buy? Are these sealed, eg, waterproof?
