eufy Baby Monitor E21 is the best hybrid here because it gives parents a real choice about Wi-Fi. The included 5-inch monitor connects straight to the camera, and a physical switch on the camera decides whether it also joins your home network for app viewing. With Wi-Fi on, eufy says you can share access with up to 5 family members, and video is encrypted with RSA-1024 and AES-128. The 4K camera pans 330 degrees, tilts 60 degrees and zooms up to 8x, which is useful for checking a lost pacifier from the hallway. Its 5,000 mAh battery runs the camera for about 9 hours unplugged, so it can go to a nap at a grandparent's home or keep working in a power cut. Active noise reduction cuts background noise by up to 20 dB. It does not track breathing or sleep, and a second camera adds $129.99. We compared documented features and published prices.
