Overview
The Tapo C840 is a dual-lens smart baby monitor, pairing a 2K 4MP wide-angle lens for whole-room coverage with a 1080p telephoto lens for close-ups. It adds baby-specific AI — cry, covered-face and sleep detection — plus lullabies and a night light, on top of being a capable indoor camera.
Key Features
Setup & Compatibility
Set up in the Tapo app — the C840 supports 2.4GHz and 5GHz Wi-Fi. Mount it with one of the three included stands (cot, wall or shelf), pair the included night-light button, and set up baby profiles and BabySnap in the app.
What’s New
This is a baby monitor built on a capable dual-lens camera: a 2K wide lens covers the nursery while a 1080p telephoto lens stays on your baby’s face, with cry, covered-face and sleep detection layered on top.
