A:AnswerThis model does have 3 HDMI ports. There is not a camera in any of our Vizio TVs. The remote that comes with this TV does not have a number pad on the remote however, an on screen number pad does appear on screen when needed. The voice command feature of the voice remote can be disabled. Thanks!
