It’ll need to be a usb camera, any will do but the Logitech ones are good quality and affordable; c920 and c922. Will u be streaming directly from Xbox, or Xbox to pc? If it’s the latter you’ll also need a capture card. Streaming straight from the console is fine, but just be aware you’ll be very limited when it comes to customisation, and console usually isn’t the most consistent when it comes to frame rate and internet bandwidth. Use an Ethernet cable if possible
