D1 Smart Lock

0.4 second 3D face unlock with anti-counterfeiting binoculus algorithm

The D1 is the speed-focused face lock in the range. Its 3D facial recognition chip uses an anti-counterfeiting binoculus algorithm that measures the depth of facial features, recognising a registered face in 0.4 seconds and operating in full darkness. A 4200 mAh lithium battery, Tuya app connection and compatibility with wood, steel, stainless steel, aluminium and brass doors make it straightforward to specify across a mixed project.

OEM and ODM discussed per order. Finish and packaging on request. Scope TBC with our engineering team.

How it compares

The D1 is the fastest recogniser in the D-series at 0.4 seconds. The D6 adds ultrasonic approach detection, the D18 adds palm vein, and the D2 adds an indoor display peephole. Take the D1 when speed, battery capacity and broad door compatibility lead the decision.

Installation and use

Enrol each household member by face and keep a passcode as the secondary method. Connect to the Tuya Smart app at commissioning so failed-attempt alerts reach the right phone from the first day.
