The
Meetinghouse Technology Policy, Webcast: 8.2 Appropriate Use: See Handbook 2: Administering the Church, 18.3.1 and 21.2.10. 18.3.1 is a section of Stake Conference. 21.2.10 is the prohibition against recording/broadcasting from the chapel already noted.
Edit:
Webcast Policies and Guidelines:
Webcasts should not be used to broadcast ordinances such as baptisms or the administration of the sacrament.
"Meetinghouse webcasts are intended to be used to broadcast events from one Church building to other Church buildings. Webcasting to locations other than Church buildings should only be done under the direction of the event's presiding authority.
I don't know as webcasting was intended for anything other than stake conference. It does appear to be a stake function. And as a practical matter, I don't know as it would work reliably when the general membership has access to WiFi.
Recording is a different matter. I'm not sure of any guidelines, but I'd wonder if it wouldn't inhibit some classroom discussion. But your stake president would be the one to talk to.
