There's turning it off in the Teams app, and there's also closing the lid. I was curious as to whether the camera keeps operating with the type cover closed (My SP7 and home PC share monitor/kybd/mouse), and when I attend a meeting I just plug in a headset. It appears that the other attendees just see me as a black screen.
Camera is enabled, but SP-7 sits on my printer where it blends in nicely. Never have to touch it. I don't want to open the stand etc. just to attend a meeting. Messes up my DP and USB cables if I do that. The only reason I asked about the camera was that ideally we want to see how the audio/video traffic load the VPN, but there are enough other mobile users online.
