The Best Door Viewers for Apartments and Houses

Safety and security are top priorities for homeowners and apartment dwellers alike. One of the simplest yet most effective tools to enhance your home security is a door viewer, commonly known as a peephole.
Door viewers allow you to see who is outside your door before opening it, providing peace of mind and preventing unwanted intrusions. With so many options on the market, choosing the best viewer for your apartment or house can be overwhelming. This article breaks down the top viewers available, their features, and what to consider before making a purchase.
What Is a Door Viewer?
A door viewer is a small optical device installed in a door that allows residents to see the outside without opening the door. Traditional door viewers use a fisheye lens to provide a wide-angle view, enabling you to identify visitors from a safe distance. Modern viewers may include digital cameras, video screens, or even smart technology integration.
Why Do You Need a Viewer?
Enhanced Security: Identify visitors without opening the door.
Increased Convenience: Check who’s there before answering, avoiding unnecessary interruptions.
Child Safety: Allows children or elderly family members to see visitors safely.
Deterrence: Visible door viewers can discourage potential intruders.
Key Features to Consider When Choosing a Viewer
Viewing Angle: The wider the angle, the better you can see outside. Most viewers offer angles between 160° and 200°.
Installation Size: Measure the thickness of your door to ensure compatibility. Standard peepholes fit doors 35mm to 70mm thick, but there are options for thicker doors.
Type: Choose between traditional optical peepholes or digital viewers with screens.
Night Vision: Some digital viewers come with infrared night vision for clear viewing in low light.
Smart Features: Certain models can connect to your smartphone for remote viewing.
Privacy: Look for viewers with covers or shutters to prevent outsiders from looking in.
Material and Durability: High-quality brass or metal viewers last longer and resist tampering.
