Easy to use, good video quality, worth the price
Rachel✓ Verified Purchase•October 5, 2023
I had the original Eufy baby monitor (non-wifi version). I loved about almost everything of it, but I wish it has the tilt and pan function when I zoom in. So we upgraded to the newer version for the second baby. The wifi connection is surprisingly quick and reliable, so we can just use our phone to check out the baby and never have to reach for the standalone monitor anymore! The 2K video is much clearer than the old 720P, so we can see the baby breathing and every little movement with confidence. I am glad that Eufy kept the price manageable and it is worth every penny of it.
peace of mind for parents

I recently purchased a baby video monitor and smart sock, and I am extremely happy with both products. The video monitor provides high quality images, even in a dark bedroom, and the price is reasonable.
One of the standout features of the video monitor is the clarity of the images. Even in a dark room, the monitor is able to capture clear and detailed images of my baby. This is particularly useful when she is sleeping, as I am able to see if she is breathing.
In addition to the high quality images, the video monitor has a number of other useful features. It has a two-way audio feature, so I can talk to my baby if she wakes up, and there is a zoom function that allows me to get a closer look at her.
The smart sock is another great feature of this baby monitor. It is able to track my baby's heart rate, and it sends alerts if there are any changes. This gives me peace of mind, knowing that I will be notified if there are any issues with my baby's health.
Overall, I am extremely happy with this baby video monitor and smart sock. The high quality images, reasonable price, and added peace of mind from the heart rate monitor make it a great investment for any parent

Needs monitor

Only thing this needs to be 5 stars is s separate monitor so you do not need to use your phone. An O2 sensor would be nice too
Customer service is great
David Long✓ Verified Purchase•September 11, 2023
I had previously written a negative review when I was frustrated after the camera stopped working. I did finally get it to work again an hour later. The customer service department reached out to us based on a previous review willing to go above and beyond to help, which we really appreciate.
A peaceful mind for parents

I got these monitors duo because my baby was sick and I would like to have device to constant checking on my baby and alert me if there is some emergency situation happened at night. Eufy is great that it comes with a speaker that will give you warnings if baby's heart beats are out of range. After a few nights of no sleep that I was constantly checking on my was sick baby, I finally can sleep better because I know I will get a sound alarm through the speaker device that both my husband and I can hear the warming while sleeping, instead of getting notifications on phone like other brands which will be highly possible not heard during sleeping. The device gives me a peaceful mind when my baby was sick at night. Highly recommended.
