Our webcam with built in twin microphones is Logitech C920.
The sex workers' favourite, apparently. Barakta recently took delivery of a friend's spare one, and other than a bit of arsing about because Windows 10 isn't ready for the desktop (if the camera isn't accessible due to some privacy setting, why not give an error message to that effect, rather than emulating the symptoms of an incompatible driver ffs?), it seems to work well. Not only does it avoid nostril-vision, but it does an excellent job of exposure control in quite challenging settings (barakta has a window with the setting sun over her shoulder, and a low tolerance for light on her face). And it's a real lens that can actually - FOCUS YOU FUCK - on things at close range.
I remain sceptical about the merits of video for online collaboration, but it seems to be the way the disability activists are going as - given BSL interpretation, captioning and sparing use of the chat channel for deafblind users - it seems to be the least-inaccessible option for most people.
