They use a few models and are changing from time to time. One of them uses a DSLR camera to a BlackMagic HDMI to PC interface and it's really really great. Close to "best." But I bet they invested over a thousand.
Nod to the 100 buck range Logitechs for better than average but "best" will push us into a few thousand bucks.

I have a HP Pavillion 6823w with Win 7 Home Premium OP and want to know the best model Webcam for my computer that I'd be able to stay in touch with grandkids, clear video and audio and the best place to get the Webcam.
