Hi, I'm looking to create a video system for doing classroom demonstrations, where the students do not have to gather around a desk to see the work and I have got a bit lost looking at kit! Ideally I'd like a couple of cameras - one zoomed in and one more of a wide shot. Where the lecturer (who might not be technically competent) will be able to switch simply between the two. I'd like to distribute the video to 2 or 3 screens around the class room. Can anyone help with what cameras to go for and what distribution kit I'd need? Budget isn't huge but the kit will be installed and left alone. Thanks in advance!!
