## Description

4K camera for baby monitor E21

Review: Love this camera. Optical zoom would be better but 4K digital works good enough to see what’s going on. Seamless connection and reconnection over wifi and directly with monitor. Great job Eufy.
Review: I received this item and was disappointed at first because it would not connect on my app and it was spotty in connecting with the monitor. I reached out to the Customer Service team and they offered a replacement. They asked a few simple questions, had me send a couple of pictures and determined I needed a replacement. The biggest surprise was the speed-they either had decided to send me a replacement before they told me they were sending one, or it was sent overnight-priority because I had the discussion with them late on a Wednesday afternoon and it was at my house by Thursday lunch-I don't think I have ever gotten anything that fast. The cameras and monitor do work well, along with the app, no complaints there but the customer service is likely what will bring me back with the Eufy brand.

## Features

- Full Protection with Split-Screen Monitoring: Check in on your babies from anywhere at home, with or without Wi-Fi. Whether you're at work or traveling, stay connected through the app and share access with up to 5 family members for extra support.
- 4K UHD Resolution to See Every Detail, Day and Night: With a 330° pan, 60° tilt, and 8× zoom, you'll catch every corner and facial detail, even seeing their chest rise and fall in the dark thanks to crystal-clear night vision. If you have twins, monitor both with two feeds on one split screen.
- Travel Made Easy with Plug-In or Battery Power: Powered by a 5,000mAh battery, this camera goes anywhere with your baby. Move it around at home or take it to your summer cabin or hotel for seamless care during trips and gatherings. You can always count on it, even during outages.
- Sleep Tight with Noiseless, Smart Monitoring: Get ready for some well-deserved rest. It comes with active noise reduction tech to cut background noise by 20 dB. Plus, 24/7 recording in the app helps you uncover any sleep issues for your little one.
- Full Privacy and Security in One Switch: Toggle the switch to cut off Wi-Fi for a secure, private local connection. With RSA-1024 and AES-128 encryption, hackers and unauthorized users are kept at bay. Every recording is protected with a unique key for absolute peace of mind.

The perfect monitor. Clear view, clear audio, easy setup and works perfectly. Love the ability to disable WiFi. I have used every single brand of camera and this one is far above the rest! Eufy historically has exceptional customer service which makes it even better if an issue pops up.
