Most of the locks I've seen in my area still have a path for light to bleed through, but it's very, very tiny. Most likely not enough for this application. But peepholes are still a thing, not everyone has a cover on the apartment side, and the effects of the fisheye lens in the middle could be compensated for with a bit of extra math...
