And it’s getting harder and harder than find a TV that isn’t a “smart TV “
Especially a better quality ones. But you don't have to connect them to your network. No one can access the camera or microphone if it's not connected. For the most part, the "Smart" TV's have crappy quality interfaces and are inferior to even cheap external devices like Fire or Roku. My Panny Plasma has a built-in camera and mic, but I have no desire to use my TV for Skype or any other function involving the cam/mic.
