A door viewer, also known as a door peephole, is a small optical device mounted on a door that allows people inside the door to observe outside the door without opening it. It enhances security by allowing visual confirmation of visitors or potential intruders before allowing entry. Traditional or optical door peepholes (classic peepholes) often use fisheye lenses to provide a wide panoramic view, ensuring a wide field of view. This simple design, no power supply required, is widely used in residential environments and low-security premises due to its reliability and cost-effectiveness.
