Style: 4K baby monitor E21
Such a great quality! Other cameras I've seen do not have high quality videos but this one does! I personally don't use the app but I love using the monitor and take it with me when baby is sleeping. I only bought this camera because it is hybrid with wifi and uses less EMF. The only con for this camera is I constantly need be charging the camera if it is not connected, other than that its great.

Style: 4K baby monitor E21
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.

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.
