Even when having Night Vision within Main Hall 3 (aka CAM 05), it may not be as useful as the room is dark, and there is not much sight of anything, also seeing the animatronics eyes within the room will give it away.

Blank also appears in this area to smash the Office window and gain access into that area. The characters Candy The Cat, Cindy The Cat and Blank all enter this area, however, Blank moves in the camera in this area when he smashes into the Office window.
