We run some internal training sessions. I want to record them so we can use them for other things like YouTube. I don't want to just put an SLR on a tripod, they put people off interacting and the courses need participation. I want something unobtrusive. I was thinking a couple of ceiling mounted WiFi PTZ cameras recording to a PC with a couple of joystick controllers but a) they might be noisy as they move and b) the audio will be poor. I can't imagine you can put radio mics on the presenter and feed them to the cameras. So I'm looking for recommendations for fixed controllable, cameras with decent audio that will pick up everyone in the room (c12 people). With a £1000-1200 budget for 2 cameras and audio.
