DOOR LENS

A door lens typically refers to a peephole or a small optical device installed in doors to allow occupants to see outside without opening the door. It enhances security by providing a discreet way to observe visitors before deciding to open the door. Door lenses often have a wide-angle view and may incorporate features like privacy covers or digital displays for added convenience. They play a crucial role in home safety, offering a means of visual verification before engaging with someone at the door.
