Hi there
I think these days any "generic" web cam gives sufficient video quality -- what is usually appalling is any sound -- this is where effort needs to be concentrated -- audio chips can be made tiny and very high quality incredibly cheaply so why do we always have to put up with hideous sound when using webcams for skype, zoom , other online meetings etc.
Using a phone isn't an ideal solution either as then the audio and video can easily get out of sync - especially if using any sort of blu tooth device / chipset.
I think the OP should worry about sound quality --even a cheap and nasty web cam these days will yield a full HD (1920 X 1080) picture / video stream --more than good enough for typical video conferencing unless you have huge mega cinema size screens / monitors.
Even on Youtube there's an incredible amount of really poor sound -- probably too many people have got used to wearing those dreadful cheap bud earphones. !!!
Cheers
