eufy FamiLock S3, Smart Wi-Fi Palm Vein Recognition Keyless Entry Door Lock, 3 in 1 Front Door Security Electronic Lock, BHMA Grade 1

The eufy FamiLock S3 has been a huge upgrade for me, especially after returning the Lockin Veno. Assembly was surprisingly simple and frustration-free. Everything fit together intuitively, and the instructions were clear enough that I had the lock fully installed and running in far less time than I expected. What really sets the FamiLock S3 apart from the Veno is the feature set. The responsiveness of the fingerprint reader, the smoothness of the touchscreen, and the overall build quality all feel a step above. The app integration is cleaner too, with faster updates and more reliable notifications. After dealing with connection hiccups and slower response times on the Veno, this lock feels like a breath of fresh air. Another big draw for me was eufy’s strong security reputation. Their focus on privacy and local data processing gave me a lot more confidence in choosing a smart lock that would actually protect my home without sending data who-knows-where. It’s reassuring to know the company behind the product takes security seriously. Overall, the FamiLock S3 has been easy to set up, easy to use, and packed with thoughtful improvements over the lock it replaced. I’m genuinely glad I made the switch.

My son recommended the Eufy Security Smart Lock Familock S3 after using this brand and model himself for quite some time. He has had a great experience with it, especially because it is easy to use, reliable, and does not require a monthly subscription. Our installation was straightforward, and the instructions were fairly simple to follow. Adding users to the system was also easy. The lock can accommodate 20–30 different users, making it a great option not only for a home but also for a small business office or rental property. Each person can have their own unique PIN code, so you don’t have to worry about everyone sharing the same access code. I really like the added security features this lock provides. The built-in camera allows me to see who is approaching the door and sends alerts when someone is detected. The camera quality is impressive, with a very clear picture during the day and excellent night vision after dark. The video is sharp and easy to see, not grainy like some security cameras can be. I feel confident being able to clearly identify visitors whether it is daytime or nighttime. The two-way audio feature lets me speak with someone at the door through the small built-in speaker. I can also view the camera anytime, capture a snapshot of visitors, and even unlock or lock the door remotely when I’m away from the property. One of my favorite features is the palm recognition access. The lock uses the unique vein pattern in your palm to identify approved users, adding another level of security and convenience because there is no need to carry keys or remember a code. However, it also includes a backup PIN code option, which provides extra peace of mind in case the palm sensor is ever unavailable or has an issue. Each authorized user can have their own individual PIN, so everyone does not have to share the same access code. The access controls are another great feature. You can set limits for each user, including specific days and times they are allowed to enter. This makes it especially useful for businesses, rental properties, or anyone who needs to provide temporary or scheduled access. I also appreciate the automatic locking feature, which can be turned on or off and adjusted to lock anywhere from immediately after closing the door to up to 5 minutes later. This gives you flexibility depending on your needs. Overall, this is a well-designed smart lock with a lot of useful features. The combination of a high-quality camera, clear night vision, palm vein recognition, backup PIN access, remote control, individual user settings, and no subscription fees makes it a great value for anyone looking to add convenience and security to their home or business. Since I haven't had it installed for very long I can't actually give you a review on the battery life. My son said he has used it for quite some time and the battery life lasted him about 5 months before he had to charge it. And then the battery was only at the halfway point.

I bought this to replace a separate doorbell and lock, and it definitely cleans up the front porch. The 2K video is sharp, and I love that there’s no monthly subscription fee to see my clips. Installation was straightforward and took about 30 minutes with a standard screwdriver. Pros: • No Subscriptions Huge win. Local storage is the main reason I went with Eufy. • Camera View. The 180-degree lens actually lets me see packages sitting on the ground. • Build: The lock feels heavy and secure—doesn't feel like cheap plastic. Cons: • The Palm Reader: This is the headline feature, but it’s not perfect. It works about 85% of the time on the first try. If your hand is at a slight angle or if you’re standing too close, it usually fails and you have to reset and try again. It’s still faster than keys, but not as "instant" as I hoped. • Bulk: It’s a very large unit. If you have a screen door, double-check your clearances because this sticks out quite a bit. It’s a solid upgrade if you want to ditch your keys and your doorbell subscription in one go. Just be prepared to have a little patience with the palm sensor until you learn exactly where it likes your hand to be. Battery life is long

When it's good it's good, but when it's bad its bad. It's super slow to pick up people walking to the door and alert you and i have had so many guests have problems using this touchpad because half the time it doesn't light up. I will never buy a eufy lock again.

I really wanted to love the Eufy Lock S3 — palm vein recognition, multiple unlock methods, and a sleek design all sounded great. Unfortunately, real-world use has been disappointing. The connectivity is unreliable. The lock frequently shows offline in the app, notifications are delayed or sometimes never arrive, and remote access can be hit or miss. For a smart lock, that’s a major downside. The palm vein recognition, which is supposed to be the standout feature, is inconsistent. Sometimes it works instantly, other times it fails multiple times depending on lighting or hand position. That’s frustrating when you’re standing at your door trying to get in. Another big issue is that this lock is not well-suited for single doors. The design and alignment of camera especially at night times video/image quality is so poor. The price fluctuates very often, which is also annoying. One day it’s listed at a premium price, then it drops significantly, then goes back up again. That makes it hard to justify buying something that already feels inconsistent.
