Here at Ecampus, we use a Sony Z1U to record lectures. It’s a nice camera.

Victor found a sweet add on, that would save us a ton of boring time. (waiting for tape to play back video, while the computer captures). A Memory Recording Unit.
Supposedly you can stick any solid state flash card in there, and it’ll dump to it while recording to tape. And reviews claim that it doesn’t use any crazay proprietary sony format (which is why i usually fear sony products).  SD pops up in AVI, HD in Mpeg2 (? i might need to check that…).
