Fantastic
Already had the set with the monitor, bought this add on for the new baby. Works flawlessly with the other camera and monitor!

Camera is very good and customer service is A++
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.

I thought I loved this brand until this purchase
I thought I loved this brand until I bought this. What good is a WiFi security camera if it doesn’t work? The problem is their app and cloud are broken. The camera works via the monitor, works and shows online for one user via smartphone but offline for another user. It’s an awful experience when the camera you rely on simply doesn’t work. Also, tried creating a new account to share the devices with and it says the account is already registered but when using forgot password it has to email you a code but then says it can’t send a code because the email is not verified. Trash system. Avoid at all costs.

The perfect baby monitor!
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.

Favorite baby monitor!!
Love this baby monitor!! I love that it’s a hybrid so I can see what’s happening through my phone app when I’m not home since it can use WiFi or we can block WiFi and have a more secure connection. Picture quality is great, battery life on the parent monitor is excellent, and I LOVE that you can set an alarm to go off when it detects a baby cry. No more monitor anxiety at night when you’re trying to sleep and constantly listening for your baby to wake! I love that it also has the same app for our security cameras and my breast pump!

Camera has good night vision. In addition it has wireless capability that makes this camera a cut above the rest. If your ever on vacation you can use the wireless feature in order to see in places power may not be near.

Great camera add on to E21 monitor
This easily hooked up to my original E21 monitor. It's super easy to use and see both my children at once and the app is great. The picture quality is amazing; I can't go back to our old monitor now without feeling like it's super blurry.

Not a reliable camera.
If you are not wanting to use the camera you purchased this is the camera for you. I have had so many issues with getting it to work. I have a very tech friendly home and this is the only device that is always trying to connect. When it works it’s great but then it loses connection and I’ve tried restarting it, unplugging it, changing the video feed to 1080p, restarting it, reformatting the sd card (thinking it was lagging from that), updating it, restarting it, updating my router, restarting it… nothing is working. If you are looking for something reliable DO NOT go with this camera.

Works well
It adds a cam. Minor issues with sharing with multiple people, likely partner related in my case.

Love it
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.

Best Add-On Baby Cam
As we have two kids, we purchased this add on camera after buying the initial Baby Cam 4K Pack. Camera works just like the one provided in the initial pack. We love that we can use the monitor or our phones from anywhere. We own several eufy products and once again they hit a home run with this. Thank you!

They should be truthful
It looses signal a lot and I am not that far away from it, I am not very happy with it I got it to help watch a sick child and what I read on it said it was good I will not say that rate it as very poor
