Brass Door Viewer

1. Knowledge about the Door viewer
1. Principle of the door viewer

The door viewer is primarily composed of a concave lens and a convex lens, working together to provide a wide and secure field of vision.
The concave lens compresses the scene outside the door, allowing it to be projected into the viewer and forming a clear, three-dimensional virtual image. The convex lens then magnifies this image, enabling residents to clearly see what is happening outside.

People standing outside the door cannot see inside through the viewer because, from their perspective, the concave lens functions as the objective lens, which has a very short focal length. As a result, the image cannot be formed clearly, preventing outsiders from seeing through the eyepiece.

This optical design allows residents to observe and assess the situation outside the door safely and discreetly, providing an important layer of protection for home security.

2. Door viewer installation
Before installing the door viewer, the customer should measure the specific diameter of the door viewer. Then, drill the suitable hole in the right position of the door and install the door viewer. In fact, after buying the door viewer, most people will choose to ask a professional team for the installation of the door viewer, which will be safer and cost-effective.
