Choosing by market
Dual-screen locks sell on video call and face recognition, so the buyers care about the app, the interface language and the network. All four models use Wi-Fi 2.4 GHz and the Tuya app, with TTLock and Matter on selected models; see Tuya, TTLock and Matter for the platform choice. Door fit is the other half: the 68 body covers most steel and wooden entrance doors, and the rear lock can be changed on request.
How to choose
- Metal look and the largest outdoor panel: A60S in aluminium alloy.
- Glass panel with CNC engraving in black: A57S or A67S.
- A second colour option: A20S offers black or grey.
- A lower-spec version for price-sensitive markets: ask us about the basic B67S without AI.
