Good Quality high resolution
I like leaving a review after having a product for sometime, so i can give the best honest review….. I got this door camera over a year ago in May 2023, it was a great purchase. I had one issue with the camera sensors and not recording 3 months after installation, it was a quick and easy calibration fix, no problems since then. The camera quality is high clear picture resolution. The fingerprint sensor is a plus, especially with young children that can potentially forget the door code. The door can be locked or unlocked thru the phone app and also locks auto with adjustable minutes of choice. Doorbell volume can also be set to preference or silenced. Battery life will last anywhere between 3 to 6 months depending on use. It only comes with one rechargeable battery. The battery does take a few hours to fully charge approximately 6, so I recommend buying a second battery to have fully charged in hand (well worth it and convenient). Also the app is easy to use and installation is quick and easy. Overall I highly recommend this door camera. It won’t disappoint.

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.

It went from Almost perfect to perfect. Read on to understand what I mean.
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.

This lock/doorbell is great. The camera is clear and the accompanying app works really well. Notifies you when any activity is around the door. You can control everything remotely and the WiFi is strong.

This lock is a game changer! So easy to set up and install. And works flawlessly after. The battery life is great and so is the app. Also as a bonus the chime and storage is inbuilt!
