3D face recognition

Security at financial-payment level

The D200i uses genuine 3D structured-light face recognition with living-body detection — the same class of tech as an iPhone — not the flat 2D scans that are easier to spoof. A dedicated dual-core Cortex-A53 AI chip wakes the cameras in 0.1 seconds and unlocks in under one, even in complete darkness.

Processed and stored on-device — your face data never leaves the lock, so recognition stays private and secure
Under 0.0001% false rate — 31,000 detection points map your face precisely, sharply cutting the chance of a wrong match
Works for the whole family — stores up to 50 faces and reads children and elders that fingerprint locks often struggle with

Nine ways in

Tap to enter with Apple Home Key

Store a home key in your Apple Wallet and unlock with a tap of your iPhone or Apple Watch — no app to open, no code to key in. And when your hands are full, there is always another way in.

Face, PIN, NFC & Bluetooth — pick whatever suits the moment at the door
Temporary passwords — one-time or scheduled codes you can share for guests, cleaners or short stays
"Hey Siri, unlock the door" — voice, remote app unlock, and a mechanical key as the final backup

Fully automatic lockset

Locks itself the moment the door shuts

A motorised, integrated lock body throws the bolts automatically — no lifting the handle, no second thought about whether you locked up. Pull the door closed and the D200i secures the house on its own.

Direct-insertion C-class cylinder — the highest consumer anti-pick grade, backed by an electromagnetic anti-interference design
All-round warning system — alerts for a door left ajar, unlocked, pried, repeatedly wrong codes, low battery or away-mode breaches
Emergency ready — a hidden USB-C port and mechanical key get you in if the battery ever runs flat

Recognises you on approach

The door greets the whole family

A wide 1.3–2.0 m recognition range picks up adults and children as they walk up — so the door is already open by the time you reach it, hands full or not.

Built to guard, built to last

Peace of mind, day after day

Whole-house smart link

Pair with an Aqara hub so unlocking can trigger lights, aircon and scenes, and locking up can switch the home to away-mode.

Months on a charge

A near-5,000 mAh battery lasts over four months, and a spare battery is included in the box for an instant swap.

Tested to endure

IP52-rated against dust and splashes with an IP64 face module, and passed a 96-hour salt-spray test for humid Singapore conditions.
