Verdict: A Rare Low on a High-End Smart Lock
The Eufy palm detection smart lock deal is a strong smart lock discount, making a premium model with biometric keyless entry, integrated 2K camera, and broad smart home support far more affordable for people who want security-focused tech without paying full flagship pricing. This is one of the more advanced smart lock deals available today, and the drop to its lowest recorded price means you are getting high-end features at a mid-range cost rather than luxury pricing. If you have been waiting for a feature-packed lock with camera, keypad, and biometric options, this is the moment to buy rather than hold out further, especially as stock and timing are not guaranteed. "This model normally comes priced at $400, but can now be found on sale from Amazon, knocking $120 off, dropping it to its lowest price of $280."
What Makes the Eufy Palm Detection Smart Lock Special?
The standout feature here is Eufy palm detection, which lets you hover your hand over the lock and unlock the door if your palm pattern matches. This avoids many of the problems seen with fingerprint validation and adds a biometric authentication layer beyond traditional keypad or app-based entry. The lock also includes a sharp 2K camera with a wide field of view and an inner display, so you can see who is at the door without reaching for your phone or a separate smart display. On the connectivity side, it supports Matter, Apple Home, Google Home, Alexa, SmartThings, and more, making it a flexible centerpiece for smart home security setups. This combination of biometrics, video, and broad ecosystem support is rarely seen together in one device at this kind of discounted price.
Eufy FamiLock C32: Cheaper Biometric Alternative
If you want biometric keyless entry at a budget level, the Eufy FamiLock C32 smart lock is also discounted separately, offering about a quarter off its usual price. It focuses on fast fingerprint access with a 0.3-second unlock time, 360-degree recognition that helps children and elderly family members enter easily, and storage for up to 50 fingerprints so the whole household can have their own profile. The keypad is built into the door handle for a sleek, futuristic look, and you can monitor and control the lock from anywhere at any time through the connected app, removing the need to hide spare keys under mats or pots. It uses four AA batteries for about five months of life, plus USB-C emergency backup for power, and works with both Amazon Alexa and Google Assistant for hands-free convenience.
Why Smart Locks (and This Deal) Are Practical
Smart locks eliminate the need for risky spare key habits like leaving one under the doormat and instead rely on codes, biometrics, and app control. With both the palm detection lock and the FamiLock C32, you can monitor and control the lock from anywhere via mobile apps, adding peace of mind when you leave home or forget to lock the door. Customizable auto-lock settings mean the door can secure itself after a set time, and biometric authentication adds a security layer that is harder to copy than a key or PIN. The palm detection model’s inner display and 2K camera further support smart home security by showing who is at your door while integrating with major platforms for wider automation. Paired with other discounted devices like a battery-powered video doorbell, you can build a comprehensive smart home security bundle at a lower total cost.
