3D Facial Recognition and Biometric Capabilities
We appreciate that the product highlights 3D facial recognition rather than simple 2D imaging, which suggests improved anti-spoofing performance and better recognition across lighting conditions and angles. While the presence of 3D tech is encouraging, we recommend confirming the exact sensor type and anti-spoofing mechanisms in the manual or spec sheet before relying on it for high-security needs.
Fingerprint and Finger Vein Recognition
We like the dual biometric approach: fingerprint and finger vein recognition. Finger vein recognition is usually harder to spoof because it reads subcutaneous patterns, and combining it with fingerprint sensors can improve both convenience and security.
Other Unlock Methods: Card, Password, Mechanical Key, Tuya App Remote Unlock
We value the redundancy: card access, password entry, and a mechanical key provide fallback options when biometrics fail or when batteries run low. The Tuya app remote unlocking adds convenience for remote guest access, but we recommend setting strong account protections to prevent unauthorized use.

Notes on Dimensions and Fit
We recommend measuring the door thickness, backset, and existing cutouts carefully. The listing directs users to Figure 2 for specific dimensions, which we should review to ensure proper fit. If those technical drawings are absent, we advise contacting the seller.
Installation and Setup
We find installation will likely require some careful measuring, drilling or using existing cutouts, and possibly basic wiring if the unit expects a wired power input or auxiliary sensor connections. Most users should be able to install the lock with common hand tools, but having a helper for alignment and testing will make the process smoother.
Tools and Skills Required
We suggest basic tools: screwdriver set, tape measure, pencil for marking, and possibly a drill and chisel if the door lacks the required cutouts. If the lock includes a mortise or latch hardware that differs from the existing system, some carpentry skills or a professional installer may be required.
Wiring and Power Considerations
We cannot confirm the exact power source from the provided details, so we advise checking whether the lock runs on batteries, a wired supply, or supports both. If the lock uses batteries, ensure you install fresh batteries and consider keeping spares; if it supports an external power input, plan the wiring route and test the power before finalizing the installation.
Tuya App Integration and Remote Unlocking
We appreciate Tuya integration because it opens access to a broad ecosystem of smart home controls and remote unlocking capabilities. That said, Tuya cloud accounts, app permissions, and network stability all affect the remote experience, so we advise setting up secure credentials and testing remote access from multiple network conditions.
App Features and User Management
We find that Tuya typically offers user management, user logs, temporary access codes, and sharing features. Use these tools to grant time-limited access to guests, workers, or service personnel and monitor entry history if the app supports event logs.
Security Assessment
We believe the combination of 3D facial recognition, fingerprints, and finger vein scanning represents a layered security approach that exceeds many single-factor smart locks. However, security is only as reliable as implementation: sensor quality, encryption of data and communications, and firmware update policies all matter.
Resistance to Physical Attack
We recommend verifying the lock’s physical grade, anti-tamper features, and resistance to forced entry. Mechanical backup is helpful, but a weak strike plate or latch could still be a point of failure; reinforcing the door frame and using heavy-duty screws can improve physical security.
Privacy and Data Handling Concerns
We encourage checking how biometric data is stored (on-device vs cloud) and what encryption the vendor uses for communications. If biometric templates or unlock logs are stored in the cloud, we advise enabling strong passwords and two-factor authentication on the Tuya account to reduce risk.
Performance: Speed and Reliability
We expect facial recognition and fingerprint scans to unlock the door almost instantly under optimal conditions. In real-world environments, factors like lighting, user positioning, and finger cleanliness can affect speed and reliability, so plan for occasional re-tries.
Facial Recognition Accuracy
We like that the unit specifies 3D facial recognition, which generally yields more accurate matches and fewer false accepts than simple 2D systems. Still, we recommend testing the system with multiple users, various lighting conditions, and while wearing glasses or masks to confirm real-world accuracy.
Fingerprint and Card Recognition Speed
We find fingerprint unlocking typically takes less than a second on modern sensors, but older or lower-quality sensors can take longer and present false rejects. Card access and password entry are usually consistent but depend on the card tech (RFID/NFC) and keypad responsiveness.
Battery Life and Power Backup
We can’t state the exact battery life because the listing doesn’t include power specifications, but smart locks with biometric sensors and wireless connectivity often have higher power draw than simple electronic locks. Expect to replace batteries more frequently if you use remote or cloud features heavily.
Low-Battery Contingency Planning
We advise setting up low-battery alerts within the Tuya app, if available, and keeping a mechanical key or emergency power terminal accessible. Some smart locks include a micro-USB port for emergency external power — confirm whether this model supports that feature.
