3D Face Recognition Smart Door Lock with 1080p Camera
Quick take
This biometric smart deadbolt pairs 3D face recognition with palm vein scanning, plus fingerprint, passcode, IC cards, and an emergency key, giving you many ways to unlock. It also includes a 1080p video intercom with two-way audio and supports remote control and notifications through the Tuya app, with Alexa compatibility. The main buying caveat is that buyer feedback about app functionality and support responsiveness is mixed, so it is smart to plan for a backup access method and verify app performance for your setup.
Pros and cons
Pros
- Multiple unlock options (3D face, palm vein, fingerprint, passcode, IC cards, emergency key) for flexibility.
- 1080p video intercom with two-way audio for seeing and speaking to visitors from your phone.
- Automatic locking plus an alert feature for tamper attempts, with notifications sent to your phone.
- Tuya Smart App remote access and Alexa voice integration for convenience.
Cons
- Review evidence is limited and includes reports of the app becoming less functional, including face recognition stopping after installation.
- Fit matters, since you need to check door measurements before ordering (mortise lock installation).
What buyers think
Buyer-review evidence is mixed, with overall satisfaction mentioned in multiple short comments about quality and usability. However, there are also reports that the app experience can be problematic, including cases where only limited app controls remained or biometric features stopped working after setup. Because the review sample is relatively small and details vary, buyer-review evidence is not strong enough to confirm consistent long-term app performance. Overall, shoppers appear to be most attracted to the lock’s design and broad feature set, while some buyers raise concerns about software reliability and getting timely support.
Who this smart lock is best for
This lock is a strong match if you want a biometric-first door entry system but also like having fallback ways to unlock. It is especially suitable for households that have different preferences (or changing conditions like glasses or masks) and for families that need multiple access methods for trusted guests and deliveries.
- Biometrics-focused buyers: You get both 3D face recognition and palm vein scanning, plus fingerprint, passcode, and IC cards.
- People who want video intercom convenience: If you want to communicate with visitors remotely, the included 1080p camera and two-way audio are central to the feature set.
- Home automation users: Alexa compatibility and Tuya app control let you monitor and control from your phone and integrate into a smart home setup.
Key features that matter day to day
Unlocking options for real-world scenarios
The lock is designed around choice. You can use 3D face recognition, palm vein scanning, fingerprint, a secure passcode, IC cards, or an emergency key. In practice, that means fewer lockouts if one method is temporarily inconvenient (for example, if a phone is unavailable, or someone does not want to use biometrics).
Video intercom with two-way audio
Instead of only a door camera, this system supports two-way conversation. That can be helpful for deliveries, guests, and package handoffs, since you can speak directly through your smartphone using the Tuya app.
Auto-lock and tamper alerts
Automatic locking helps maintain consistent security behavior after closing the door. There is also an alarm approach intended to trigger on tamper attempts, with immediate notification delivered to your phone.
Power strategy: battery with USB-C emergency backup
Power is battery-based, and the lock includes USB-C emergency power as a backup option. If you want a setup that does not require hardwiring, this approach reduces installation complexity, but it also means you should keep an eye on power levels and have a plan for recharging.
Multilingual interface
The on-lock interface supports multiple languages, which can be valuable for mixed-language households or rentals where guests may be unfamiliar with a single-language setup.
Pros and cons of the biometric approach
Pros
- Redundancy by design: With several unlock methods, you are less dependent on one sensor or one credential type.
- Speed-oriented face access: Face recognition is intended to be fast and designed to work in common real-life conditions.
- Unique biometric types: Palm vein scanning adds another biometric layer rather than relying on one modality.
Cons
- Software reliability matters: Some buyers report app and biometric feature issues after installation, which suggests you should confirm that the Tuya app experience is stable for your household.
- Setup and fit impact performance: Because this is a mortise-style lock that requires correct door measurements, a poor fit can complicate installation and day-to-day reliability.
Installation and compatibility checklist before you buy
Before ordering, make sure your door supports the required mortise lock setup. Measure carefully, and review the included installation guidance if you are planning DIY installation. Also consider whether you have reliable Wi‑Fi coverage at the lock location since remote access and notifications depend on app connectivity.
Price and availability
The current listing price can change over time, and availability may be limited. Check the live price and stock status before committing.
Verdict
Buy the 3D Face Recognition Smart Door Lock with 1080p Camera if you want a biometric smart deadbolt with palm vein and face unlocking, plus a video intercom and strong remote-management capabilities. It is a good option for households that value multiple access methods and want to answer the door from their phone. If you prefer to rely entirely on app-controlled features and biometric functions, consider the mixed buyer reports as a reason to confirm your setup, keep a non-biometric backup plan ready, and ensure you can get help if something stops working after installation.
