A digital peephole replaces the optical viewer with a camera and screen. It suits apartment doors where a doorbell camera is not allowed.

Prices are approximate, converted from what Amazon displayed on October 31, 2026 where needed. This guide is built from product listings, not our own testing, so check peephole size compatibility and door thickness on each product page.

How We Chose These Products

We start from products sold on Amazon with a full product name and clear specifications, and we skip results that show only a brand name or a vague title. We then read the listing and any manufacturer information for each one and note the features that matter for security cameras and doorbell products: power type, storage, subscriptions and Wi-Fi requirements. We do not run our own lab tests, and this guide contains no hands-on measurements. Use it to build a shortlist, then check current prices, dimensions and return terms on the Amazon page before you buy.

Buying Guide: What to Check Before You Choose

Power, storage and subscription

Battery doorbells install anywhere but need recharging; wired ones use doorbell wiring. Check whether video is stored locally or in the cloud and what features need a plan. See our doorbell camera buying guide.

Wi-Fi coverage

A weak signal causes lag and dropped video. Place an extender between the router and the camera, and check the band your camera uses, which is often 2.4 GHz.

Smart lock fit and security

Check the door prep, backset and battery. Choose reputable models and strong codes, and keep a backup key.
