… or there's just a lot of awkwardness for both parties in trying to communicate "are you on camera?" without the person who is potentially on camera revealing that communication to the stream.
The person entering has to make sure they're not on camera — if the room's architecture even allows for that — the person answering has to somehow communicate to that person without people looking at their video feed noticing. I've gestured things to my fiancée while on air, and while they were pretty clearly intended for "someone off camera", still managed to confuse the meeting participants.
Radio booths and other broadcasts have done this for ages with the "On Air" sign, which basically what TFA has made.
