Wall mounting tablet with hidden power supply

[pls1]

I'm looking to wall mount a tablet (probably Android) to run Action Tiles so it will show CCTV & various sensor status.

The wall mount part is straight forward as there appear to be plenty of universal holders on eBay that will mount it against the wall.

I was thinking to sink a double back box behind the tablet and run a mains supply into it (spur) and then use a 230AC to 5v DC transformer with a micro USB cable connected to the LV side. This would then power the tablet.

Does this sound like a good solution? I can't find anything else off the shelf that might do it other than a single faceplate with USB outlet & transformer built into the plate. Doing it this way though means the USB plug would poke out and could not be concealed which is not what I want.

The wall is also solid brick and not stud work so couldn't conceal much behind it other than what I can put in a back box.

I think I've figured it out, looking at the site above they sell a PoE to USB power adaptor that converts 24v to 5v.

In my case I have a PoE switch that outputs 48v and I found a 48V to 5v micro USB splitter cheap on Amazon that will do it. I can stick this in the back box and mount the tablet over the top.

Looks like that PoE splitter is the best way forward.

For when I’ve done similar, I’ve used a brush strip in a Euro module faceplate.
Most electrical companies do the faceplates so you should be able to match your current sockets if you have a preference.
Here is the link to the brush strips, two needed for a double faceplate. They look better once installed.
