Vision as part of their techconnect range now have an infra red blaster device which can learn your projector remote control signals for a fixed installation.

It will turn them on/off, change sources, volume control so it won't do the fancy features such as freeze, zoom etc..

Well it could but there aren't any labelled buttons in the box for those and they've used rubber printed buttons, plastic ones with replaceable keycaps so you could design your own would have been nice.

£80 may be of interest to some people.

TBH all our teachers need is to be able to turn the things on and change source so it's perfect for us.
