eufy Security Baby Monitor Baby Smart Sock with 2.4 GHz Wi-Fi, Track Sleep Patterns, Naps, Heart Rate, No Monthly Fee

After owlet discontinued the support for older socks, we were faced with a decision I wasn't expecting. After some research we decided to go with eufy, and I'm SO glad we did. We have been using this every night for about a month now, and so here's the in-depth review I wished I could have had at the time I was looking. The sock design is so much better than other ones out there. I have no struggles putting it on since the sensor goes right on the top of the foot. Super simple. I also personally have not had any issues with the sock part being super worn or falling apart either, though she only wears it at night. If it does happen to come off for any reason, the base calmly tells me and there's a little image that lights up. It is so much better than the blaring music of previous products I've had. I personally rely on the base rather than phone notifications and I've had no issues. You can turn off the notifications it does if you want to keep it in baby's room (since it does charge it). It is wonderful for peace of mind, but it does so much more than that. It tells me how good my baby is sleeping, when and how often she woke up, her heart rate, her oxygen, if she's moving around, and how much sleep she got overall. I have my daughter in a mini crib a few feet away and this wonderful base has an image that lights up when she's wiggling, and will stop when she stops. It has helped me not get up every 5 seconds to check on her when I hear noises, making my sleep so much better. I have not had any issues like other people have reported regarding the oxygen sensing. It has never been suspiciously low. The oxygen sensing is in BETA testing so it will NOT notify you if something weird happens on the oxygen front, but you can always look at it in the app. It will notify you of a drastic heart rate change though. I would suggest going into the app settings and changing the heart rate notification parameters a bit so you get an earlier notification if something starts going strange. I love the app. It is simple and straight to the point. You can also invite other people (dad) to have access to see what's going on and be notified as well. The only issue I've had is the sock not charging from putting it on the base a tiiiiny but off. It will make a noise when it starts charging so make sure you listen for it. The battery life is a little over 24 hours, so I have used it on low battery a second night and the base will tell me calmly when it's about to die. For the price, I am so impressed. I would get this over other monitoring systems out there, especially if you can use HSA or FSA funds. Love it so much. So thankful.

I’ve been really impressed with the Eufy baby camera. The picture quality is crystal clear—no more squinting at pixelated blobs wondering if the baby’s asleep or plotting an escape. I also love the flexibility: the camera runs unplugged, so I can easily move it wherever my baby happens to be napping or lounging. Whether it’s the crib, the playpen, or the occasional baby throne (aka the bouncer), this thing keeps up. The monitor itself is solid—good size, responsive, no lag—and the app is intuitive and user-friendly. I’m not wasting time fumbling with settings when I should be watching my kiddo. Now, the one (mildly annoying) quirk: when you go to dock the monitor on the charging cradle, it insists on turning itself back on. So if you’re trying to save battery or avoid lighting up the room, don’t bother turning it off manually—just plop it in the cradle and let it do its thing. Bottom line? Great camera, smart design, and reliable performance—just be ready for that monitor to have a mind of its own at charging time.

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.

This is a great baby monitor but it isn’t perfect. You cannot continuously record. If you want to know when your baby wakes or falls sleep, unless they make noise to trigger a recording, you won’t know. It kind of defeats the purpose of the massive SD card we purchased. The night vision is very clear. We have taken this monitor on trips and the built in wireless system reaches a good distance. Sometimes we have to reboot the camera to fix connectivity issues. Overall, it’s a great product, but won’t log all videos.

So glad I purchased! We’ve been using this sock for five days now and so far so good. I am able to put it on my two month old with one hand while I’m half asleep and it monitors him perfectly. I have had no issues with the sensitivity of the charging base. The charge lasts nearly two days, but we are only using it at night. Setup was simple, it did take about twenty minutes for the app to start reflecting data but has not lost connectivity since the initial setup. There has been no irritation of my son’s skin with the sock on and he isn’t bothered by it at all. Needless to say all my initial concerns about this vs the more expensive sleep sock have been eliminated. I also love that the app is completely free. Wish I had purchased this from day one!

Has been a great comfort for my at night and I have been able to get more sleep. Love the app feature because I can check oxygen levels and adjust baby if I see numbers are on the lower side of normal. If the sock were to come off or were to not be in place , which has not happened by accident ( I was just testing to see what would happen), the device tells me working something is wrong within 2 seconds of this happening. Sometimes the app glitches out but like anything else as soon as you exit the app one or two times it shows you the updated info. Even if the app glitches for a minute the base would tell you if babies heart rate or oxygen were abnormal. Am so happy with the device I had to leave a review.

This monitor checked all of our boxes that we wanted. Great camera quality, auto zoom with one click, split screen, wifi & non wifi, SD card video storage. Unfortunately, I have some complaints. The alert notifications when the baby moves or cries will not go away unless you press a button on the monitor. Each time my baby moved the notification would come up and block the view. This can be tolling during the middle of the night when wanting to check our baby from bed but there is a notification blocking the view. I tried turning off the notifications but then the monitor stopped turning on when my baby cried which is not okay. Very little options when adjusting alert notifications. We also had shoddy connection with this camera which made it unreliable. And the mount that came with it broke after 1 day.
