I have a wireless camera setup by eufy and needed to replace my existing video doorbell. So I took the plunge to a battery setup as the existing power to the doorbell was not enough to make it function. In the setup I told the doorbell to only react to humans as I have a different eufy wireless camera in the garden, with solar charging, but didn’t cover the actual door area and not a doorbell camera. That camera I record everything so I only needed human motion to know and keep a record of who was at the door. It exceeded my expectations, works great, and with only human detection the battery lasts quite awhile. I bought a spare battery for it, so I can change it and the charge up the second battery inside for next time it needs to be changed. Camera quality is awesome! It’s easy to setup, and I have it linked to my eufy base station and do backup video to the eufy cloud (extra charge). This is not required but feel better with a backup. The unit does have a place for a microsd card and comes with a wedge I needed to install due to the angle of the location the original doorbell was installed. As for connectivity it works great with no issues getting signal back to the base. The motion setting on low helps to limit what it responds to. Highly recommended and wish I had done this years ago. Useful video and looks awesome! Also the audio is clear on both ends!

Finally ripped this thing out last night after breaking down and buying a Ring. I had it up for over year along with a full Eufy system and the local hard drive base station. A few cameras around the house and this doorbell. I will say the video quality of these cameras is great. Going after the fact and reviewing footage was nice and you can see in great clarity everything. The night mode worked well also. But if someone came and actually tapped the button, forget it, all bets off. The system would panic, app would crash, or the video would be so laggy and choppy/pixelated you could never get a stable conversation going. Absolutely useless. We not once in over a year of having this made one successful call. I even moved an eero WiFi station extremely close to the front door to ensure a solid connection and performed multiple factory resets, all in vain. Got a ring last night, hooked it up, been working flawlessly. Hate the monthly sub but it’s worth paying for a device that WORKS. EUFY got caught illegally collecting footage of owners and had to change their marketing to secure encryption but never fixed their jank software. It’s full of spelling errors, incorrect labels, crashes frequently, a while back they combined their security app and cleaning (robot vacuum) apps in to one and wow now they’re both worse in the same app! I went all in with eufy from their security system to two robot vacuums and have slowly been moving away from them due to a whole host of problems with everything. Avoid this brand like the plague. You’ve been warned.

I have been using Eufy exterior light cameras and doorbells for several years now. I really like the system for a couple reasons. First, I don't like the idea of my videos being maintained by a centralized vendor system. Second, I appreciate that there are no fees associated with using the system like so many others. In the past, I found the instructions to be well written and the packaging to be very good. The manual had a font that was large enough to be easily read. But what has always concerned me is the way they role out new products doesn't seem to show any concern for their previous customers. For example, when they dropped Apple Home (HomeKit) support when they moved from HomeBase 2 to HomeBase 3. At the same time, HomeBase 3 did not support a wired doorbell until this model was introduced several years later. So I've been open to change systems since they dropped support for Apple Home. What I would really like is support for Matter over Thread, but there aren't even any rumors the company is showing any interest in that. With that in mind, I was hesitant to invest anything more in Eufy, but a Black Friday deal on this doorbell. What intregued me was that it had a battery, but could be hooked to normal doorbell wiring in order to keep the battery charged an provide coverage during power outage. I just installed this so this is really an initial review. This is my initial impression. First off, as others have commented on, the directions are terrible. For one thing, the printed one in the package uses such a small font, you can only read it with a magnifying glass. There is a scan code that will take you to a manual and you can download a PDF that you can then read on any device ... but gone is any of the style Eufy used to use in their manuals ... extremely basic. While it covered the install pretty well, there is no explanation of ANY of the settings in the app. In addition, the manual had no spec sheet with information like width of the doorbell or how much memory does it have without adding an SD card. An SD card is not included so how much is the doorbell capable of storing in stand alone mode. I was surprised to learn this doorbell does not work with any previous Eufy chime. What I don't feel is explained adequately if there appears to be four chime options. The three options are in a paragraph that describes how the system works independently it describes three options, the home's existing chime, a Eufy Chime (sold separately) or using Amazon device as a chime. It then describes using doorbell with Homebase, but neglects to say Homebase can be used as a chime. To add to the confusion, the only Eufy chime that is compatible is referred to as a Minibase Chime which can be used to store videos like HomeBase. What is funny is the very first thing described in the manual is how to set up the Minibase Chime even though it is not included in the kit. This takes me to another item not adequately explained. The SD card slot. It shows it in the breakdown diagram identifying items on the doorbell ... but in the description it simply says lift up silicone lid to insert the SD card. I believe there is also a hinged metal frame for the SD that has to be lifted to insert the SD, but if so, the instructions don't mention it. The only other thing that is said about the SD is in the instructions for the Minibase, it says to move the SD from the Minibase to the doorbell. It doesn't say anything about how this memory card would be used when doorbell is being used independently or with Homebase. Upgrading from a previous wired doorbell, I expected the base that is screwed to the doorframe would be the same, but it wasn't. The size of the hole for the doorbell wire is the same, but it is higher in the frame ... so either the doorbell needs to be mounted at least 1/2" lower (i.e. old mounting visible) or you can drill a hole in the plastic frame where it needs to be for the wire. This is what I did. The wiring is very tight and makes it difficult to snap the doorbell onto the frame. I'm thinking I may go back and cut a larger opening in the frame to better accommodate the wire. The video quality and performance is on par with the other Eufy products I have. I do appreciate that it works with Homebase S380. I'm hoping at some point Eufy will produce a new hub that will them provide their system compatibility with Matter over Thread. Now to figure out what is different in the app. It just seems that with moving to more electronic documentation where you don't need to worry about the cost of printing, that it would be nice to use that to provide a manual that really answers all of the questions regarding the product.

Best thing we did. No contracts easy to operate and excellent video and sound quality. So good we installed at our parents too and told all the neighbors. Great product. Recommend using the home base to store the videos. Works great in low light conditions.

I installed this in December, 2024. Pros: + No subscription required + affordable + decent night mode + wide viewing angle + can be powered from legacy 24VAC house doorbell wiring if you have a diode (none provided) + Up to 128 GB Sdcard (not included). I installed the maximum size. That was *WAY* over-kill. It probably has a year of video stored. + captures video any time motion is detected. So I get videos of package deliveries even when doorbell not pressed. Very handy. Cons: - As much as 5 minute notification delay from time doorbell is depressed and Eufy app on phone will alert. The phone alert is unreliable. Numerous times a visitor would ring the doorbell while I was away and by the time the Eufy app notified me they had already left assuming nobody was at home. Annoying. - My house has entry alcove and doorbell is mounted on one side facing opposite wall. When mounted flat against wall the camera's wide field-of-view did not capture approaching people or motion in driveway. A 45-degree wall mount adapter was required. I could not find one to fit so I designed my own and 3D printed it.

The C31 worked on the Eufy app when I first installed it. It appeared to work on the Alexa app on the iPhone but then did not. It did not work on my Echo Show 8. I installed Eufy Homebase S380 to see if that worked but it made no difference. I was away and tried to access the camera in my iPhone and it worked. But would not work when at home. I disabled Wi-Fi on the iPhone and the Alexa app worked when on cellular. I then went online and found that Echo Show and the Alexa app over Wi-Fi requires port forwarding on the router. I added the required port forwarding and it works!

I have several eufy cameras and added this one to our set. I love that it can either be used wired or by battery. We set it up wired, which I’d recommend if you can. I love that eufy has local storage so you don’t need to pay monthly to look at your videos! Microphone function works great and it’s easy to set up and use. Recommend this camera and the eufy brand.
