Product Details
Biometric Access
Radar sensing activates 3D facial recognition as you approach. The biometric system is designed to distinguish enrolled features from imitation attempts such as photos, videos and artificial models.
Everyday Access
Palm vein recognition offers another contactless way to unlock. Hold your palm near the recognition area for access without using the handle-mounted fingerprint reader.
Remote Video Intercom and Live Viewing
With the supported connected app configuration, check the live doorway view, speak with visitors remotely and authorize opening from your phone.
4 Inch Indoor Display
The built-in 4.0-inch screen lets household members see visitors and check the doorway from inside the home.
Flexible Access and Alerts
Fingerprint, passcode, card, mechanical key and temporary code access complement the biometric options. Anti-pry, low-battery and incorrect-attempt alerts support daily security.
Compact Design and Rechargeable Battery
The 211 mm × 73 mm panel combines a familiar lever with a compact profile. A rechargeable 2500 mAh lithium battery powers the lock.
Applications
FAQ
What is the difference between 3D face and palm vein?
3D face recognition works at a normal standing distance, while palm vein reads the veins under the skin and needs the palm held close to the sensor, which helps when a mask or gloves make face recognition inconvenient.
Which app does the ETV-I4 use?
Tuya Smart or TTLock, depending on the app configuration ordered with the lock.
What door thickness and power does the ETV-I4 take?
Doors from 40 mm to 120 mm thick, powered by a 2500 mAh rechargeable lithium battery with a 4.0-inch indoor display.
