What Is a Peephole and What Types Are Available?

A peephole, also called a door viewer or peep hole, is a small optical device installed in a door to see who is outside without opening it. Common options include standard glass lenses, wide-angle viewers, and modern peephole cameras designed for added security.

How Do Door Peepholes Work?

Door peepholes work by using a small fisheye lens that bends light to create a wide-angle view of the area outside the door. This allows you to see visitors, packages, or activity directly in front of the entryway from inside.

Can a Peephole Be Added to an Existing Door?

Yes, a peephole can be added to most existing wood and metal doors, including front doors, apartment doors, and condo units. Peepholes can also be replaced if the existing viewer is scratched, fogged, or outdated.

How High Should a Peephole Be Installed?

Peepholes are typically installed between 4.5 and 5.5 feet from the bottom of the door, depending on who primarily uses the door. In some cases, additional viewers can be installed at different heights for accessibility or shared use.

Are Peepholes One-Way or Can Someone See Inside?

Traditional peepholes are one-way viewers, meaning people outside cannot see in through the lens. Some newer models include cameras or digital displays that provide enhanced visibility while maintaining privacy.

When Should a Peephole Be Installed or Replaced?

A peephole should be installed when a door lacks visibility or replaced when the lens becomes damaged, loose, or unclear. Upgrading an old peephole can improve both visibility and entryway security.

How Much Does Peephole Installation Cost?

Peephole installation costs typically range between $500 and $1500, depending on door material, thickness, and placement requirements. Pricing can also vary based on whether an existing peephole is being replaced or a new one is installed.
