In answer to a recent question left on our blog, although we have three cameras working all the time, we only have two image feeds on the web. The pictures they show do get varied as activity changes - our second page currently shows a "multi-view" with all three camera images merged into one. Images change every 8 seconds or so. We do not currently have the capability to offer live audio/video.
Apologies from the Project Team for not responding to all questions recently. In our own way each of us is very busy, and free time is rather at a premium.
