According to this guy in one of his other videos where he mentions this, the people at Crytek are fine with players doing this on the PC, and players have said it encourages them to use the Nanovision more.

That sounds grand, but on the 360, I barely use nanovision at all, because it's super cloudy and I can't see jack through it.

It would be awesome if we got this clearer nanovision in a patch for the 360, as it would encourage people to use it more and negate a great deal of the cloak camping. Seems easy enough to do on the PC end...... :/

Nano-vision drains energy so quickly that it's more trouble than it's worth to use. That and seeing cloaked enemies isn't terribly difficult without it. I think to make it useful some aspects of the game need to be tweaked to make it a necessity. As it stands now it's a cool add on with no real in game need.
