They sit in the library and have a whole set up with laptops and a control board w/pan, zoom, camera switching, etc. They got so good at it, the stake called them to do the stake broadcasts as well. These 2 guys are both studs. We may call a third to provide more of a rotation.
We have a number of folks who have been sick or are battling cancer and can't come, so they've started broadcasting Relief Society as well using some sort of camera on a stick I believe.
