security camera power supply

[RN62]

I've bought a 12v security camera and it comes with a plug in power supply.
I could just plug it in to a socket but that would mean a rather ugly looking set up with the wire running from a socket under the carpet and floorboards, or possibly through a hole in a bedroom wall.
I'd rather wire it in under the floorboards, here's what I'm thinking.
Run a cable to a fused spur which then feeds a 12v transformer which will sit under the floorboards.
Then feed the output from the transformer through the wall.

So, am I breaking any rules by doing this?
Is there a better way?
I'd be glad to hear any advice.

Thanks

Not a sparks myself but transformers get hot, I wouldn't think it wise to fit in a confined space under floor.

Agreed, but there are 12v transformers feeding some of my lighting circuits and they're in the same space.
Any sparks watching that might advise?

Maybe I should move this to a different forum.
