Up and running thanks to "how to" guide from Robert Wisbey. See how it was done here
Hopefully you should see a black box above this text. Clicking on the box should start the camera. It might take a little while to come through, and the camera is not active 24/7.
If you are looking at a blank area on the screen, you won't be alone (thanks Annie). I'll try to get it sorted, but don't hold out too much hope.
