Who it fits

Key specs explained for you

3D Face Recognition in under 0.5 seconds

This speed allows hands-free entry without touching the lock. You can approach the door and be unlocked almost instantly. This is useful if your hands are full with groceries or packages. It also works in darkness or with masks. When comparing smart locks, look for similar fast facial recognition speeds to ensure convenience during daily use.

1080p HD Camera

This resolution provides clear video footage of visitors at your door. You can see facial details and package labels clearly. The wide-angle lens captures a broader view of your entryway. This helps you identify who is outside before opening the door. Compare this with other video doorbells to ensure you get high-definition clarity for security monitoring and package verification.

4200mAh Rechargeable Battery

This capacity powers the lock for six to twelve months. You receive app warnings weeks before it dies. A USB-C port provides emergency power if needed. This reduces the frequency of battery changes compared to standard AA battery locks. When shopping, check battery life to avoid frequent maintenance. A larger capacity means less hassle for busy households.

Palm Vein Biometrics

This method reads blood flow patterns inside your palm. It is harder to fake than fingerprints or facial scans. This adds a layer of high security for your home. It works well for family members who may have worn fingerprints. Compare this feature with standard fingerprint locks to see if you need this extra level of protection against unauthorized access.

C-level Security Cylinder

This is a high-security standard for mechanical locks. It resists drilling and picking attempts better than lower grades. It protects the physical lock mechanism from forced entry. This is crucial for front door security. When choosing a smart lock, verify the cylinder grade. A C-level cylinder ensures the physical part of the lock is as strong as the digital features.

Design and build specs

According to the listing, the We Technology RL11 is constructed from anti-drill aluminum alloy with a C-level security cylinder. This material choice suggests a focus on durability against forced entry. The lock body is described as a 6068 mortise design, which is a standard for residential doors. You should verify that your door thickness and edge dimensions match the product photos before purchasing, as installation compatibility depends on precise measurements.

The unit measures 3.5 inches in width and 4 inches in height, with a total length of 18 inches. It weighs 9 pounds. This substantial weight indicates a solid build, likely providing stability on the door. The finish is black, which helps the device blend with most exterior door frames. The layout includes a built-in 1080p camera and a display screen for the 9-language interface.

Controls are integrated into the front panel, allowing for palm vein scanning, fingerprint recognition, and keypad entry. The placement of these sensors is designed for hands-free or touchless operation. You can also use IC cards or mechanical keys as backups. The rear panel houses the 4200mAh rechargeable battery and the USB-C emergency charging port. This internal layout keeps the exterior clean and minimizes exposed wiring, contributing to its weather-resistant appearance.

Setup and daily use guide

Setting up the We Technology RL11 involves checking your door measurements against the product photos before ordering. The listing includes an installation video to assist with the physical mounting process. Once installed, you configure the 9-language interface on the screen. You can choose from English, Arabic, Russian, Portuguese, Thai, Spanish, Vietnamese, Indonesian, or Chinese. This setup ensures clear voice prompts for all household members.

Daily use relies on the Tuya Smart app for remote management. You can unlock the door via 3D Face Recognition, which takes under 0.5 seconds, or Palm Vein Biometrics. The palm scanner reads blood flow patterns, adding a layer of security that is difficult to fake. You also have options for fingerprint entry, secure passcodes with anti-peep features, IC cards, and mechanical keys. The lock auto-locks after every close, removing the need to manually engage the bolt.

The built-in 1080p camera and motion sensor send real-time alerts to your phone. You can view visitors through the Tuya app and use two-way audio to speak with guests. Recorded events save to the cloud, allowing you to review footage anytime. The system supports Alexa integration for voice control. Power comes from a 4200mAh rechargeable battery, which lasts 6 to 12 months. The app warns you weeks before recharging is needed. A USB-C port provides emergency backup power if the battery drains completely.

Before You Buy This Lock

You need a stable Wi-Fi connection for the Tuya app to function. The lock relies on cloud storage for video history, so an active internet link is essential. You should also verify that your front door aligns with the listed dimensions. The unit weighs nine pounds, so ensure your door frame can support this load without reinforcement. Alexa compatibility allows voice control, but you must check if your existing hub supports this integration. Battery maintenance requires periodic charging via USB-C. The 4200mAh battery lasts up to twelve months, yet you should monitor the app indicator regularly. This lock integrates video doorbell features with high-security biometrics. It suits users who want hands-free entry and detailed visitor logs. If you prefer simple keypad-only locks, this model may offer more complexity than needed. Consider your door’s thickness and backset before purchasing. The installation video helps, but precise measurements prevent fit issues. This device sits at the higher end of smart locks due to its camera and dual biometric systems.

Check before you buy

• Verify your door dimensions match the product photos.
• Ensure your Wi-Fi signal reaches the entryway.
• Check Alexa compatibility with your current smart home.
• Confirm your door frame supports the nine-pound weight.
