yes thats what the red "ruby" lens coating is about, it buffers reflection from the lens surface.

sometimes i go to the suite at random intervals and swipe the card open the door then lock up and leave for another while, hoping it screws up any attempt to make a pattern.

i dont think the point is tracking your patterns [that is an issue of itself tho] i think the more proximate issue is that a criminal may photograph record or live stream our intimate moments that occur when there is a full expectation of privacy.

Has anyone considered these pieces of equipment?

They are very hard to spot. you have to inspect the area of concern for tack holes or raised features in the wallpaper. As far as price is concerned, there is a fair bit of profit that will be realized short term from the disgusting type of porn that could be generated. Im sure there is some gaurded position regarding sales of these devices, if not there should be.
