Maybe cliche' by now, but still creepy . . .
Quote from 1984 About Telescreens
"The telescreen recieved and transmitted simultaneously. Any sound Winston made, above the level of a very low whisper, would be picked up by it; moreover, so long as he remained within the field of vision which the metal plaque commanded, he could be seen as well as heard. There was of course no way of knowing whether you were being watched at any given moment. How often, or on what system, the Thought Police plugged in on any individual wire was guesswork. It was even conceivable that they watched everybody all the time. But at any rate they could plug in your wire whenever the wanted to. You had to live- did live, from habit that became instinct- in the assumption that every sound you made was overheard, and, except in darkness, every movement scrutinized.

Quote from Katherine Boehret Allthingsd review about Xbox One with Kinect:
A Skype video call to my mom prompted a “Wow!” from her as she admired the quality of the picture, which she described as amazing. As for audio, she said she could hear me just as clearly when the loud, humming central heat clicked on in my house. As I moved around the living room and talked to my mom from six different places, the Kinect camera panned to follow me, and even zoomed in on my face for the best possible picture. I had a similarly good experience during a call to someone else who was using the Xbox One’s new Kinect.
