Peepholes and Viewers

"Commercial peepholes and viewers are essential security accessories for doors in commercial settings. Peepholes, typically consisting of a small optical lens, allow occupants to discreetly view and identify visitors outside without fully opening the door. Viewers, often more advanced, provide a wider and clearer view through a fisheye or wide-angle lens. These devices enhance security by allowing users to assess the identity and intent of individuals seeking entry, helping to maintain control and safety within the commercial space".
