The Brinno DUO Peephole Doorcam works on 4 AA batteries; no wiring involved. It replaces the standard peephole so it can be installed even in rental apartments. Its unique Duo mode allows access both on its built-in screen and from this app at the same time!

Every Brinno DUO door camera includes a knock sensor that activates the recorder when a visitor knocks on the door. It also supports up to 6 optional remote motion sensors. If you want it to, your Brinno DUO will send an email that includes 3 pictures every time its sensor is activated.

Brinno DUO records to a removable SD card so it works even when the internet or power is down.

Your recordings are not stored on the cloud (no monthly charges!). This app knows how to talk directly to your personal Brinno DUO camera.

The recordings on the SD card can be reviewed from the Brinno DUO screen and also viewed from anywhere by using this app.

What’s New

Version 2.7870.19

This release increases the timeout for the "Files" button to handle SD cards with tens of thousands of captured images. For extremely complex SD cards (50,000+ files) it might take over 60 seconds for the camera to transmit complex directories when the "Files" button is pressed. Consider replacing the SD card to restore like-new performance. If you don't want to keep the old images, the existing card can be reformatted.
