720p webcam with microphone

A camera with microphone-very easy and convenient;

It is best to read the clear words-this point needs to be considered. I don’t know to what extent the subject requires to see the words clearly, is it the fifth or the first?

If the requirements are not relatively high, 720p webcam with microphone should meet the requirements of the subject. But if consider a more professional camera, the 1080p camera is enough for most people, otherwise it would be a little overkill. From the perspective of cost performance, 720P webcam with microphone is undoubtedly the best choice.
