eufy Baby Monitor E21 review

The eufy Baby Monitor E21 suits parents who cannot decide between a classic monitor and a Wi-Fi camera. The 4K camera talks directly to the included 5-inch monitor without your home network, and a physical switch on the camera turns Wi-Fi on when you also want to watch in the app or share access with up to 5 family members. The camera pans 330 degrees, tilts 60 degrees and zooms up to 8x, and eufy's active noise reduction cuts background noise by up to 20 dB, which helps in a nursery with a fan running. A 5,000mAh battery lets you move the camera to another room for about 9 hours by day, though eufy says only about 5.5 hours with night vision on, so it should stay plugged in overnight. You get cry, loud sound and temperature alerts, white noise and two-way talk. Limits: two cameras per monitor, 2.4 GHz Wi-Fi for the app and no breathing tracking. It lists at $259.99 with a 12-month warranty.
