Vintage 180° Door Viewer

Original video credit: (ig) @kim.jacobi Standard peepholes offer only a fixed, forward-facing view, leaving blind spots along the threshold. This vintage brass viewer uses a ball-and-socket pivot that links the interior eyepiece directly to the exterior housing. Tilting the brass knob manually angles the outside lens in any direction, providing a full field of view without needing electronic sensors or batteries.
