Smart, Simple Security That Just Works
Installing the Eufy device at our main garage entry was incredibly simple and straightforward. It’s been a great addition for keeping an eye on when friends or kids come through the garage—the motion detection has proven to be very accurate. The video quality is excellent, and the app is user-friendly and intuitive. Charging and setup were both quick and easy. I highly recommend this device for anyone looking to add a reliable layer of security to their home.

I was excited about this one
It’s a pretty camera. However I can’t get it to setup. I’ve tried multiple times but it doesn’t work. I can get the device to connect but I’m unable to install the firmware. The motion detection works. I get alerts on my phone but because the software isn’t setup I can’t see it

Easy install with clear picture
This eufy video doorbell C31 comes with everything shown in the picture. This was pretty easy to install. We did hardwire it bc we read reviews about the battery life not last very long. This picture has been very clear even on rainy days and even at night. Picks up motion pretty well. There is sometimes a lag trying to view in real time - we find it’s longer than our Blink cameras which gets pretty frustrating.

Great Doorbell
The Eufy doorbell camera is great. It detects motion well and has great battery life. I wish I came with a second battery. The video looks clear and installation was easy when using the battery.

Reliable and easy to use
Doorbell has been reliable and easy to use. Video quality is sharp, even at night, and the app alerts come through quickly. It’s great that it comes with a memory card, so footage is stored locally with no subscription needed. Motion alerts work well. The chime is loud enough, setup was simple, and battery life is solid.
