As a school we're currently building a new Student Area. It's going to contain, a 50" television, mounted onto a wall, behind a perspex screen. Ceiling speakers are going to be used as well. But the main thing is the remote control, we don't want a normal one, as it will just get lost, misplaced, damaged etc. So is there any type of wired version, or some way of having a permanent fixing to change the channel?
