Lock Type: Video Lock + Fingerprint
Update to my experience: So originally I gave this particular product 3 Stars because I'm not a fan of the E330's lack of a door sensor which would not allow the door to disengage the auto lock when the door was wide open. For example, someone goes out to take care of the trash, leaves the door open for a few seconds, dumps the trash and returns to the door to find the deadbolt engaged and the door open. Apparently Eufy (Anker) saw my original review and reached out to me regarding my statements about their product. Again, I was told that the E330 doesn't have the door sensor but the S330 does. I told them that information is not clearly visible on the product page for the E330 and that with the knowledge that the S330 had the door sensor, it really makes the E330 irrelevant and should not be a mainstay on the market. Both the E330 and the S330 have the same functions and features save for that door sensor as well as the S33 coming with it's own chime which just so happens to have an expansion slot on it for memory storage of the product videos. Eufy did the unthinkable and offered to replace my previously purchased E330 with an S330 and I was elated. They asked me what I was looking for in a smart lock and I told them just what I had said in my review: the E330 was ALMOST perfect, but the lack of a door sensor left me with a little bit of buyers remorse as it, at least to me, is a crucial feature for a "smart" device that's primary function is to provide a variety of ways to lock and unlock a door in person or remotely. Eufy offered to send me an S330 to try it out and they did make a disclaimer, stating that essentially the lock does have a door sensor on it, but it does have a timer that will still engage the lock after a set time whether the door is open or not. At first this seemed sort of counter-intuitive, but I said I will give it a try anyway. They immediately shipped me the new S330 and I received it just a couple days later. Let me say this, the S330 is noticeably heavier than the E330 and I thought that was a good sign. The two models are very similar in appearance with both being advertised as a 3-in-1 Camera, Doorbell, and of course a lock. Both sport a 2K camera that is sharp and detailed with great video capture capabilities. Both can be tied to your in-home WiFi and accessed remotely. Both have excellent fingerprint readers, although I will say the S330 one is physically more robust and it also is slightly more accurate in the way of consistency. Battery life between both are pretty much the same. The more features you have turned on the more battery is used so the battery goes fairly quick if you have everything on. Based on my current rate of battery usage I am expecting maybe 3 months of battery usage between charges. Your mileage may vary as we have lots of kids and therefore lots of activity making use of the camera be it passage through the door or little ones playing on the porch. Yes, there are settings in the app for this and I will speak about that shortly. Both products have a keyhole hidden behind the button that functions as a doorbell. Just pull the button out some and allow it to pivot to expose the keyhole. Both products come with two keys which brings the number of usable ways of unlock and entry to 4: the fingerprint reader, the physical key, the keypad, and the app. The keypad is great and allows me to program a code for each of my family members (as well as their fingerprints) into the unit. Additionally, you get a notification on your phone when programmed members use their code or fingerprint to enter the door. You can set each member to have constant access or temporary access via these methods. As stated previously, the S330 comes with it's own chime which in this case is like a programmable doorbell. It is something that you simply plug into an outlet and it carries 2 additional functions to it being a doorbell: 1) It acts as a hub/extender for the door lock. So if your router is a little further away from the door you can place the chime somewhere between the router and smart lock to gain a better signal, 2) this is where you can install an up to 128GB micro SD card for video storage, which is great if you want to store your videos locally and not have to pay a subscription. The door sensor in the S330 works great. Previously with the E330 the deadbolt would slide out with the door wide open after so many SECONDS. The only alternatives to this is to either set a schedule for a time of the day when the auto locking feature is not used or simply turn it off all together which completely defeats the point of having a "Smart" lock, in my humble opinion. Now, with the S330 the lock does in fact stay unlocked until you close the door, then the deadbolt slides into place. The disclaimer that was mentioned before had to do with the door still auto locking after 3 MINUTES time, whether the door is open or closed. I've now come to believe this is a fail safe for when the sensor may have miss the closed door event that would normally trigger the auto locking function immediately. In the case of a missed event then it would make sense to engage the lock after a set time "just in case". Either way you look at it, the lock now functions the way it's suppose to and locks and unlocks at reasonable times. Just a side note, the chime does allow for some pretty cool doorbell sounds that you can choose in the app. Speaking of the app it's very well thought out and intuitive with a robust set of features that allow you to customize your experience with the device in every practical way. Getting it on WiFi is a breeze and integrating it with Alexa is easy with the Eufy skill enabled. My only recommendations to potential buyers is 1) Try and wait for a sale on the products, whether you aim for the E330 or S330. These things are pricey and although I find that it is very useful and highly convenient, especially for larger families like mine, it is definitely a sizable investment for something that amounts to a security camera on steroids. On the other hand, it's a security camera on steroids! It allows you to monitor who enters your home or even approaches your home from afar be it your bedroom or a hotel room 1000 miles away. Number 2) Get an additional battery. Again your mileage may vary, but I've come to find that the 10000mAh battery that comes with these devices last a decent amount of time but takes a decent amount of time to charge. So, with that being said, it makes sense to have an extra battery on hand to charge while the other one is in use, set it aside until it's time to swap them out, end then go on your merry way. Both are fantastic smart locks, however the S330 is just far more practical to me. I highly recommend these products and I have to say Eufy customer service is out of this world. They have done a great job communicating with me and I feel they have been straight forward with me regarding their products. Also, I want to say I was the one that offered to rewrite the review IF the S330 met my needs and expectations, which it most certainly has. I rate the S330 5 stars, hands down. It checked all the boxes and looks great while doing it. My reasoning for my original 3 star rating for the E330 is mentioned below in the original review: ************************ This would be perfect had it not been for the absence of a door ajar feature. As some have said the E330 does not have this feature and the S330 does. For those who don't know, this feature is what tells the lock to not engage the auto lock feature until the door is closed. Without this feature the E330 is not smart enough to know that the door is open, so it just turns the deadbolt with the door wide open. The solution per the company is to turn the auto locking feature off which definitely defeats the purpose of having a "smart" lock. For the price one would think a feature like this would come standard, but I digress. Every other feature about this smart lock is very good and the quality is outstanding. The battery charge? Not long; a few months maybe. But then again I have kids going in and out all the time.

Excellent smart lock! I had a very expensive Kwikset biometric lock that I couldn't stand using any longer. I trust Eufy products as I have many Eufy items and they've all been working perfectly. This smart lock was very easy to install and the biometrics are very reliable. My old Kwikset didn't recognize my fingerprint after one day consistently. I got locked out so many times because of that Kwikset lock. With this Eufy, my finger print is recognized every single time and it is very quick to respond. AND!!! I love having the camera on it! I have it placed on the door to my garage. With this lock, I can easily see inside my garage via the app. It also can connect to Alexa. The touch controls are easy to used very responsive, hidden keyhole if needed, fast battery charging, recognizes fingerprints every time in heat or when wet from rain...what's not to love about this? The app is super easy to navigate too. If you have an Apple Watch, you can get alerts on your watch for entry, locking, battery percentage and detecting movement.

I have had this camera / doorbell smart lock installed in my for about 3 months now, and I like it for several reasons. There are no ongoing costs associated with it. Meaning you don't have to pay any annual fee for the benefit of having live video, two way communication, remote wifi control and real time alertes. There are many other options that provide the same benefits however you must pay a fee at some point. Yes the cost of entry is high but if you track this product you can purchase it at a reasonable price point. Reason number two: it has a clean sleek design that looks great on the door and the install was very easy and best of all no matter where you are you can control this smart lock. I live six months out of the year in Costa Rica and I have complete control from over 3,200 miles away. Thus far the battery pack has had no issues. I highly recommend you have some type of device like Alexa or a chime to enhance the volume of the doorbell. I chose not to purchase the chime and just intergrated the smart lock with my Alex. Eufy products are really great. Check out my reviews of their interior and exterior cameras.

I got this lock in late 2024. Less than a year later the outer layer of plastic began. To separate off the keypad, causing the keypad to register touch when no one was around. They sent me a new one and less than a year later it happened again and they won’t send a new one only give 20% off the next one because the warranty sits with the original order and not the life of the device. Software is good but hardware is bad. Even with it functioning properly the elements trigger the fingerprint sensor and it struggles to recognize my husbands finger.

I installed this lockset in June of 2024 to replace a Schlage unit that lacked fingerprint function. Since then I have had zero problems with it. I wanted the fingerprint function most of all and that has been almost perfect. We have 4 residents and everybody has multiple fingerprints registered (you never know which hand/finger will be easiest to use each time. It depends). The camera works just as it should, the doorbell function is good and the key cylinder is hidden away behind the doorbell to maybe slowdown lockpickers. Another function I like a lot is the ability to give contractors and such their own code with time and day windows (like M-W 8:00 am-4:00pm) and an expiration date. Of course it logs every activation by text and by video. It came in handy when we had paint and new floors done. And of course, you can unlock and relock the door remotely through the app which has also been helpful more than once. It does run on a proprietary battery pack with a built-in USB charging port which is something to consider. The battery lasts about 6 months between charges and give you plenty of verbal warning as it gets low. I bought a second battery (not too cheap - $65) so that I could always have one charged up and ready when the lady in the unit starts to complain about the charge level. It takes about 10 seconds to swap batteries. Anyway, I'm very happy with this unit. It works better that the Schlage lockset it replaced and has been flawless for the last 2 years.

I recently installed a smart lock on my front entry door, and it’s been a complete game-changer for convenience and security. The setup was straightforward, with clear instructions, and it integrated seamlessly with my existing deadbolt. I can lock and unlock the door directly from my phone, set unique codes for family members or guests, and even receive notifications whenever the door is accessed. The auto-lock feature is particularly reassuring—I never have to wonder if I forgot to secure the door. The build feels solid and durable, and the sleek design blends in well with my door hardware. Battery life has been impressive so far, and replacing the batteries is quick and easy. Overall, the smart lock has added both peace of mind and everyday convenience to my home. I’d highly recommend it to anyone looking to upgrade their home security without sacrificing style or ease of use.

Lock Type: Video Lock + Fingerprint
Update May 2026 (2 years): See last photo, taking off a star. The cover on the keypad has peeled away really bad over the last year or so and the keypad is difficult to see now. I'm afraid to take it off as it leaves no protection to the keypad and an online search shows zero options to replace the cover. There are third party covers but those seem to defeat the purpose of the camera. So I'm at a loss and doesn't seem worth it to replace the whole unit. Also the app has not improved in the slightest. I don't even get notifications when the battery is low or even completely dead. The rain sensor is even worse than before I turned off the feedback sound for it but now it makes me question if my keypad is even working. I'm gonna keep this since I can't really justify buying a new one with how expensive things are these days but I'm not too happy with unit's durability and app performance still. Original (2024): Absolutely love the video quality! Much better quality than my Ring cameras. Wish the video was a little longer though. The doorbell connects to my Alexa and phone to suffice as my chime. It is pretty responsive in that manner. The lock works great but I can't seem to get different codes set up for different family members. Love that there are actual keys too. Wish I could have used my old keys though as the back up but thats just my stubborn want. The fingerprint reader is a game changer! Super easy to get back in my house when my kids subconsciously lock the door on me. The unit was easy to install and fit just right and I've changed out a lot of locks in my life. Looks good too but wish my actual door was more visually appealing. This unit makes my door look even worse because it looks so nice. Battery can last probably a month or more on a full charge. I bought a spare back up battery to easily switch out when one dies. So it can still be used while charging the dead battery. I've had this for about 4 months though and only changed the battery once (or maybe twice). My problems with this are (1) I had to get a replacement unit because the first kept saying it was "jammed" and support wasn't able to help troubleshoot the issue. After installing the replacement, same issue but I had to troubleshoot the issue out on my own after many many hours since support via email took a while to respond back. Had troubles with the calibration and feel like I need to recalibrate periodically. Once I got it working, I thought this thing would be a huge step up and considered changing out my non-hardwired Rings to Eufy cameras. Yeah that's gonna be a no for the moment. (2) The rain protection is a joke and does nothing. We've been getting a lot of hard rain storms and tornados so it's often raining sideways. The rain triggers the keypad but with the rain detection on through the app it's supposed to "lock" the keypad. Instead what it does is it beeps which then freaks out my dog. It's so annoying! The app leaves a little to be desired too. It's a bit confusing and I'm not sure what half the settings are. Cool that it saves video without subscription and you can download them as needed. (3) Notifications are extremely delayed if they even pop up. I specifically got this for my back door since it leads to the room I am in most of the day since I work from home and my office is there. My family usually likes to stop by during the days and it's easy for me to see them and communicate with them or unlock the door from them without getting up from my meetings. When the notification doesn't come it makes it so they end up scaring the crap out of me. (4) I also got this so my dad, who was working on a lot of projects in my house, would be able to enter my house using the keypad whenever he needs. Although the keypad works great often times we aren't patient and try to turn the door handle while the lock is still turning, because it's slow, which then it just jams and I have to manually intervene at that point after I notice the lock beeping and talking, not because I got a notification. But hey at least the notifications are quick when it detects rain from the motion sensor but not actual people. (See my video.) Overall, love the lock itself and the video quality. It's responsive but maybe a little too sensitive. (Tell me how to actually get the rain detection to work properly PLEASE!) Also the notifications could be a little more accurate. These negative are features that I'm hoping with a firmware update will improve over time because I'm really considering switching from Ring for the video quality alone. Also the whole issue with the "jammed" lock may have been an issue with the app and not the device itself. It was just weird. So Eufy, let's get some updates and improvements to the app going. Thanks!
