Hello, the camera should be one that has as little noise as possible and a good resolution. 720p is more than enough, 1080p is even better but keep in mind that using your camera at 1080p 30/60fps will be quite taxing for your PC and unless you have a very strong CPU, you might not want to do that. An example of a good webcam would be Logitech C920 or C922. It also depends on your budget, so you could browse this topic and see the users' opinions on web cams and their go-to choices: https://steamhost.cn/steamcommunity_com/app/274920/discussions/0/490125103624106553/

I'm using Logitech C310 at 720p max and it does the job well for a $30 webcam :)
Make sure your room lighting is decent enough.
