I've never used video camera for inspections/audits and I'm not sure it would be worthwhile.
Last inspections/audits were multi-inspector/auditor, with several scribes and evaluations being performed at the same time. We did have one scribe for each inspector/auditor, and we used a Google Hangout stream for requests and information sharing. Monitors in the War Room (and other places, in fact we noted that people were just so interested and delighted with this that they simply keep following what was going on during the whole time
) were on the Hangouts stream, and there's were already plenty of information. I think a video would only make things more confusing (we did have some eyes for when inspector/auditor went out of the room, but they simply sent updates thru Hangouts or WhatsApp).
