Logitech C920 Webcam
My Use: All Twitch livestreams & Youtube recordings from my desk
The Logitech C920 is the staple of the basic webcam on Twitch.
It is a great starter camera that offers great quality & some customization needed to work with current stream platforms.
The C920 or C930 is about the best you will get in the medium camera range before going full force into a DSLR type camera for your streams.
