Well oddly enough the principal and every other teacher that I've showed it to actually really liked it so they have no problem with me having it in there, and as for powering it there is just a sealed battery (no fumes) on the floor in behind the panel. I also installled in such a way that its not hard to get the battery out so that I can take it to the autoshop to charge, but its impossible to get out unless you know the trick to it so there is almost no chance it could be stolen

I keep the faceplate with me just for that added bit of security too
