Eufy Baby Monitor E21

4K Clarity, With or Without Wi-Fi — Baby Monitoring That Never Blinks

The eufy Baby Monitor E21 keeps eyes on your little one in stunning 4K UHD detail, day or night. The camera pans 330°, tilts 60°, and zooms up to 8×, so you can follow every movement, expression, and breath — and crystal-clear infrared night vision means darkness never gets in the way. Families with twins get dual-feed split-screen to watch both babies at once.

Hybrid monitoring is the E21's signature trick: it works over Wi-Fi for remote check-ins from work or travel, and keeps working locally even with no internet at all. Up to five family members can share access through the app, and a physical Wi-Fi switch enables a fully local, private connection when you want it. Recordings are protected with RSA-1024 and AES-128 encryption.

The 5,000mAh battery makes the camera fully portable — move it between rooms, take it traveling, or set it up anywhere without hunting for an outlet. Smart alerts flag baby cries, loud noises, and temperature changes, while active noise reduction cuts 20 dB of background hum for quiet, distraction-free monitoring.
