All The Right Features
I chose this Eufy door lock because of its top rating from Consumer Reports. My second Schlage door lock failed just like the first one, so no going back to that brand. Plus, this Eufy was more feature rich and cheaper by comparison (my Schlage locks had no video or audio, just codes).The positives are overwhelming. Every little feature I could hope for – and some I didn’t think to expect – are implemented intuitively within this product. It’s clear that a lot of thought and development time went into this product, aimed at the end user experience. It’s all done the same way I might have designed it and then improved it over time.- First, the mechanical installation was quick and painless, with the lock working smoothly right away.- Second, there are so many ways to open this lock. When my electronic setup hit a snag (my own fault), we were still securing our home by using the key for a couple weeks. After electronic setup, we added three more methods. #1: We quickly created unique passcodes for everyone. #2: Our favorite method for both locking and unlocking is to use our fingerprint. #3: But quite handy is the phone app by which we lock the door from work or from upstairs when we’ve forgotten.- Third and also cool is that my wife and I both have Admin accounts for these two devices, meaning that either one of us can access the event logs, change the ringtone, unlock the door remotely, add other users, etc. from our phones. Meanwhile we setup regular access accounts for our adult children. They each can enter their unique code at the door itself to unlock, or to lock on the way out. The next time they visit, Eufy will scan their fingerprints to enable that method also for lock/unlock. Either way, the Event log records exactly who entered and when. And records the video.- Fourth, it’s so great that there’s no ongoing subscription required. I made sure everything worked before ordering the micro-SD card, but we were still able to use all of the features above plus others not yet mentioned (Live View, Live 2-way Audio, doorbell, and phone alerts). Then with a cheap micro-SD card – so easy to insert – we also have tons of video and audio storage. It’s all configurable if we want lower-resolution video to save space or perhaps no audio to save even more space. The 128GB maximum size has more than enough room for us to configure high-res everything. Then if there’s a particular video we want to save long-term, a single tap within the app downloads it to my phone.- For the fifth positive, I can only scratch the surface about how intuitively it all functions. The live feed is just one tap. The mute-myself button is obvious, again just one tap if we want to converse before replying. I pre-recorded a few auto-responses like, “Sorry, but we don’t answer the door for solicitors”. Again, my pre-recorded messages are a well-placed set of one-tap options. Motion detection is too simple a word for the continuously enhanced AI features. My list of “Events” labels significant motion as “Human Detected”. Based upon settings, I have no events recorded for stray squirrels or passing vehicles. Night vision calibration accounts for the white door jamb in the picture. Even the plug-in-the-wall Wi-Fi doorbell is great, with app-based volume control and several selectable ringtones. The auto-lock feature is configurable for different time settings and seems useful, but we haven’t turned that on yet.The negatives are incredibly minor, especially in light of the strong positives.- I’m a decades-experienced IT professional, assembly programmer, PC builder, and more. I’m “that guy” everyone calls to setup their own high-tech equipment, including a few video doorbells. Yet I struggled with the electronic side of this lock installation. The instruction booklet simply says to install the app and follow those instructions. The app itself is great, but the setup steps could benefit from some customer feedback. A key setup step is scanning the QR code from the device itself to get its Serial Number. That step was quick and efficient for the separate Wi-Fi doorbell device – which BTW comes included with this door lock. But for the video deadbolt device, the app kept telling me “Invalid Serial Number”. No problem – I can enter the SN manually. Where to find it? The app says it’s in two places: the inner documentation box, and on the door lock itself. I entered the SN from the door lock – still invalid. I entered a number from the inner documentation box – but it wasn’t exactly a Serial Number, so still invalid. There was a real Serial Number on the documentation booklet itself, different from the door lock’s SN – still invalid. In the end this was all my fault. Kudos to Eufy’s support team for a quick E-mail response when their live call center was closed for the weekend. That response asked for details including my purchase receipt. Looking up that Amazon receipt, I noticed the exact model number I purchased: “S330”. The app’s setup steps require me to select the item type before scanning or entering the Serial Number. Where I had preciously selected “Video Door Lock & Doorbell Combo”, I tried the app again and found the S330 in a not-so-obvious selection. With that choice the QR code scanned successfully, and everything worked fully a few seconds later. That quick step even integrated the video door lock with the included doorbell device. A better setup experience (A) would print the model number on the product box somewhere, and (B) would let the app select (or at least prompt for) the device type based upon the Serial Number scanned or entered. But with the one-time setup behind me now, everything about ongoing operation is wonderful.- The other tiny negative is the advertised integration with Alexa. I don’t use Alexa here except for my Fire TV remote, so I can’t speak with much expertise about how this Alexa integration should work. Amazon’s product page says (copy/paste) “WORKS WITH ALEXA Add voice control by combining with an Alexa device”. From “voice control” I expected that I could ask any Alexa device to lock or unlock the door, and perhaps have an Alexa Show display the live video. I’ve been through every possible setting at least twice, and the only Alexa connection is “Alexa as Chime” whereby an Amazon Echo will announce when the doorbell is pressed. That’s not even close to “voice control”. Again, not a big deal for me because we haven’t gone full Alexa in our household. But if we do, I don’t expect the video doorbell to integrate fully like, say, the Echo-plus-Ring bundle does.The bottom line is overwhelming positives for all the important functions plus responsive customer support. The negatives don’t affect me, so five stars. Consumer Reports was correct in their recommendation.

2 Years Later and I Still Love It!
I purchased this doorbell as the first step into the Eufy system back in Nov 2022. I was initially slightly hesitant due to the higher cost, but I fully believe it was worth it. Now, in Oct 2024, it still is working perfectly well. I barely have to charge it since it holds battery incredibly well still. I do not have the HomeBase system, so this review is coming from considering this as a stand-alone product. My favorite thing is there are absolutely no additional costs. When I purchased a Ring Doorbell, I did not know that to view anything, I would have to pay a sub, that is why I originally ditched Ring and came to Eufy. I can view everything on my phone without paying a dime to view live, view recordings, and control my doorbell from my phone.Since then, I have added multiple other Eufy products to my house and have no regrets. With this doorbell, you can set motion zones so that you aren’t picking up on the street constantly. You can also set up multiple passcodes for different people as well as fingerprints. My fingerprints have never failed me unless my fingers are too dirty or wet, but that is understandable. You can also set up allowed times for people to visit, so say you want a friend to be able to come in during the day, you can set them up with a passcode that only works from 8a-9p. Using it after those hours will reject them which is a pretty nice feature for babysitters, dog walkers, or any services that take place. I also set up an emergency code to be able to give a 911 operator should anything happen that way they don’t have to break down my door if I am unable to unlock it either manually or via the app. (As in unable to navigate my phone due to the state I am in.) Highly recommended, you can always change it after!The only negative I will note is that it has a very long delay to announcing any motion on my Alexa device; however, that might be an Alexa integration communication issue on Alexa’s end and not Eufy, that I don’t know and it doesn’t really bother me. There is also a delay on getting notifications to my phone sometimes as well. Since I am not too worried about viewing who is at my door live, I don’t mind it. I mostly got the camera to make sure I don’t have any packages stolen since I order from Amazon a lot. I have caught both UPS and FedEx leaving packages at my door that were supposed to be signed for and forging my signature which had those packages have been stolen, I would have been SOL if I didn’t have that footage recorded since they faked my signature both times! Definitely a good camera to have to ensure you don’t get any issues with that.Little bonus: if you own a cricut or labeler, there is enough space at the bottom of the doorbell to put a small “No Soliciting” sticker right below the doorbell button.

Best Lock/Camera with zero subscription required
I love this lock. It was super easy to install. If you buy a micro-SD card you don’t need to get a subscription to record (which is basically underheard of these days, cue the ring locks). I also think their app is better than ring. Very easy to navigate. We also bought a separate camera for a different area of our house, it works seamlessly. We did have one minor issue with ours, I contacted customer service, and they immediately addressed my issue. I was absolutely blown away by the service. These are the only cameras and locks I will ever buy from here on out.5 stars for the product. 5 stars for the app and not needing a subscription. 10 stars for the customer service.

I’ve been using this smart door lock with a built-in doorbell for a few weeks now, and it’s been a game-changer for home security and convenience. The installation was relatively easy with the help of the step-by-step app instructions, and the lock integrates smoothly with my smart home system. I love the ability to lock and unlock the door remotely, grant temporary access to guests, and receive instant notifications when someone rings the doorbell or enters. The camera quality is sharp, even at night, and the two-way audio is clear for communicating with visitors. Battery life has been solid so far, and the build quality feels sturdy and premium. Overall, it’s a feature-packed, reliable upgrade that adds both peace of mind and modern functionality to the front door.

I previously had a Altro Smart door, one of the few smart door with a camera, rather then needing two system.This is a major improvement over Altro’s.1) The ability to run a local server for video recording and storage directly to the chime hub is +12) The apps control and integration – especially for the start up was simple as long as you’ve got a basic level of logic setup.3) I already had the door holes and latch done from the altro, so it was a direct swap with zero carpentry work. I didn’t even need to swap the door latch, so I have a spare for the future.4) Quiet. It’s amazing how the mechanical sound of door opening and closing was so noticeable with the Altro, when I had the Eufy S330 setup and working, I nearly hear it open or shut (initially concern, thinking it wasn’t working!).Overall, great upgrade for me and so far, very pleased with it.
