Hi Richard,
there were some webcam updates in 11.08, so that's good and so I'm pretty confident that side is working. Your last line though is the clue;
>> The app is not running secure.
Most browsers _require_ that the site be HTTPS before they will tolerate use of the webcam or microphone.
see
https://www.digicert.com/blog/https-only-features-in-browsers/Given that it's trivial, and free, to make the server HTTPS instead of HTTP probably your best bet is to get this sorted out first, and then re-check the webcam issue.
(The other most common problem I see with Webcams when testing on my machine is that only one tab, in one browser, can access the webcam at a time. So when I'm cross-browser testing I need to make sure to close the webcam page on one browser before I can test the next one. That's caught me out a few times... <g>)
Cheers
Bruce
