eufy Baby Monitor E21 with 4K Camera, Hybrid Wi-Fi and No Wi-Fi Connection, A...

10/10 baby monitor I love Anker products and Eufy being in their line is awesome. The only thing I would say is there needs a few more volume adjustments. The monitor goes from 4 to 5 and 4 is too quite and 5 is really loud. Otherwise great picture quality super durable, great battery life, camera has great zoom and image quality great viewing angles, also has a good battery life. Perfect for baby rooms and common rooms!

I really wanted to love this product, and after some bumps along the way, I finally do. For the first two months, the Eufy Security Baby Monitor E21 worked flawlessly: clear audio and video, reliable connectivity, and the peace of mind every new parent needs. Then, unexpectedly, the monitor began disconnecting from Wi-Fi every few hours without warning. Despite trying everything — including a Wi-Fi extender just 10 feet away and ensuring the app and firmware were fully up to date — the issue persisted. Even more concerning was the lack of alerts when the monitor went offline, leaving us unaware unless we manually checked the app. Initially, I was deeply disappointed, especially because the core features of the monitor were so promising. But here’s where Eufy really impressed me — their support team reached out, worked with me directly, and ultimately provided a replacement unit that has been working perfectly since. The connectivity issues are gone, and the experience now reflects the quality and reliability I was hoping for from the beginning. I appreciate that the company stood behind their product and took real action to make things right. If you're considering this monitor, know that not only is it a solid product, but it's also backed by responsive and helpful support — something that matters just as much.

Updating my review here, there are quite a few more issues than I originally noticed with this camera. In fact, in my original review, I said that the camera was great, but the mounting arm was quite poor and frustrating. The company (to their credit) refunded me for the ENTIRE amount of the camera. This was almost concerning, why would you give me the entire amount back for a complaint about the mounting arm? But I think the company is moving away from this specific product and I would no longer recommend it to anyone, I'm happy I got my money back, but I'm now running into technical issues that I didn't have before. The connection is shoddy, I'm well within the 20m range, with just two (always open) doors between the camera and the monitor, and it very often has difficulty connecting or needs to buffer, this isn't very helpful when the baby starts crying but I don't see or hear it for 10-20+ seconds (or, I hear it in real life before the monitor shows it). Additionally, the monitor now often recommends (almost every time) that I switch to local connection for better streaming, but then the App doesn't work anymore. I choose 'cancel' but the prompt keeps showing up. Also, I now can no longer access the camera through the app even after turning off the monitor, because of this setting.. despite a mention of 'Smart Connect' that supposedly switches between local and wifi connection for the best performance. The Monitor itself, doesn't connect to the internet, from what I can tell, it is just tethered to the camera through bluetooth, and I think this causes a lot of the connection issues. If both pieces of hardware had wifi connections, I think we could keep a better signal. Lastly, there's a QR code sticker on the camera that you use to set it up, but be warned, if this gets ruined or lost, you have to contact support for help. There's no way to 'detect' a nearby device and connect that way (as you do with literally any other IOT device but hey). Bottom line, I'm glad they paid me back for this camera, I think it's a very poorly designed product. The Camera quality itself and monitor, independently, seem quite good (image quality, etc.), but the implementation is terrible, I will likely be throwing it in the garbage and looking for an alternative. All anyone needs in a baby monitor is a reliable and seamless connection, and this product fails in that regard, and to me it therefore fails as a product.

The only 4k dual wireless baby monitor with a battery on the market. I got this due to my old monitor not being able to push 30 feet through 2 concrete walls so I could use my house wifi with the option to turn off wifi and run from its own monitor when traveling. The unit's wireless signal is strong enough to be at full signal strength where my old one failed. Pros 1. 4k picture 2. Camera battery, frequent power outages here make this a requirement. 3. Crystal clear night vision. 4. Great sound quality 5. Motion and sound detection with room temperature and alerts. 6. Dual wireless, can be run from Eufy Baby app anywhere in the world or from the monitor. 7. Can run a second camera with split screen. 8. Has the ability to record if you add a microSD card, supports up to 128GB. Cons 1. The camera heats up, doesn't get hot enough to be worried, but it is warm to the touch. This is likely the image processor but there is no way of knowing if it is the battery. 2. The included flex mount is absolute trash and doesn't hold the weight of the camera. There are plenty of other mounting options, but don't expect to be able to use the one that is included. Overall this may be the best non-subscription baby monitor on the market and has a ton of features that the more expensive subscription ones don't have.

Overall, it works well for us and meets our needs in many ways. However, after adding a memory card, we noticed that the battery life is not as good as it used to be. Occasionally, the light flickers on and off, which sometimes wakes my baby. I’m not sure what causes this, but we haven’t taken any action yet. When the device is turned on, it also gives an audible Wi-Fi alert. Aside from these minor issues, we really like that it is portable and can be taken anywhere. We also appreciate that we can monitor it without purchasing any additional apps. The picture quality is excellent, and the option to view it on an external screen is very convenient. Overall, it has been quite impressive and sufficient for our needs.

I purchased the eufy Security Baby Monitor E21 with 4K UHD Camera and 5" display, and while the camera quality itself is decent, the standalone monitor unit has become essentially unreliable after only 8 months of use — which is completely unacceptable for a baby monitor at this price point. Two main issues with the monitor: 1. Power button failure. The physical on/off button no longer gives any tactile click when pressed. It feels like the rubber mechanism underneath has worn out or collapsed. For a device you reach for constantly — especially in the middle of the night — this is a serious design flaw. 2. Random shutdowns despite full battery. The monitor turns itself off unexpectedly, even when the battery is fully charged. On multiple occasions I've had to restart it up to five times just to get it to stay on. This is a significant reliability concern for something meant to keep watch over a baby 24/7. I expected much better durability from a product marketed as a premium baby monitor. Eight months is far too short a lifespan for critical nursery equipment. I would strongly recommend potential buyers consider the long-term reliability before purchasing — or at least ensure you keep your receipt and warranty documentation handy.

PROS: 1.) Active noise reduction 2.) Alternates the sound every 5 seconds between the two cameras and you can see both babies at the same time 3.) If the power goes out the camera has a built in rechargeable battery, so you can still see baby 4.) 24/7 recording (for this feature I believe you have to have a c10 micro SD card (max 128gb) installed into the camera. I have ordered a sandisk extreme C10 128gb for my camera) 5.) Comes with a crib mount 6.) Sound alerts to our phones , option to use critical alert option so it bypasses silent and DND modes on your iphone 7.) 4K HD 8.) Camera has a built in battery, if power goes out you can still see baby 9.) night vision 10.) Cameras LED light auto turns off in the dark 11.) Works with wifi and non wifi, so no problem if power goes out & since camera has built in battery 12.) 2 cameras and monitor bundle on Amazon is currently $359. 13.) User manual states you can connect up to 4 cameras to this monitor as well, however I’m not sure how many the split screen option shows at once. 14.) App access to view cameras from phone CONS of Eufy E21: 1.) From the reviews, it appears they are working out some kinks with the sound and other reported glitches 2.) Users have noted that the monitor doesn't play an active noise/alarm when monitor is dying or when/if camera disconnects, so you could possibly sleep through not being able to see or hear babies through the night without that alarm feature. 3.) Users have noted when you switch the wifi off, it doesn’t actually disconnect. Users have noted that Eufy support has said they are working on an update to this as well. 4.) I do not believe there is a floor stand. Not sure if pro or con of Eufy E21: 1.) User stated as a pro, but I see it as a con, monitor unit does not have a kickstand. However, it does have a charging base for it to sit upright on. I am also not sure if the Eufy requires a monthly subscription to use the app. I will provide updates when I receive the unit (set to arrive tomorrow) and begin playing with the app and setup. UPDATES AFTER INSTALL USING FOR 2 WEEKS: Monitor does not need a kickstand as it has a large base to support itself. Night vision appears as good as my infant optics. Active noise reduction isn’t great. My infant optics completely erases the sound of the noise machine, and I can hear baby clear as day. However, with Eufy, I can’t really hear the baby over the noise machine. I only really know he’s making noise when the app alerts me. The camera records noise alerts, so you know what baby was crying about. Love that! No subscription seems to be needed. I have not had any camera disconnection issues.

I got the baby monitor camera for my brother & sister in law as a baby shower present & they love it. The quality is amazing & they have even sent me pictures of my nephew that they took from the baby monitor so it is very functional. It was very easy for them to set up. This camera has given them such a stress relief that they can see him sleeping at night with the night vision when they are in another room. The battery life is also amazing & so is the motion detection since he is such a squirmy one.
