Missing here is "why"? I get adding a window to a room without windows, but I see no reason for putting a camera in front of a TV in a window. Unless maybe like, a privacy concern? They want effectively a one-way window? Even then, there are better ways to accomplish that which look better.
I mean, if I really think about it, the two I came up with is ensuring people can't look in the window and potentially something about insulation/energy efficiency of covering the window.
