The D200i instead uses Aqara's own structured-light 3D mapping — the same underlying approach as Face ID on an iPhone — projecting a pattern onto your face and measuring its depth and contours rather than just comparing a flat image. That's what lets it unlock in about a second while still being meaningfully harder to spoof than a 2D system, and it continues to work reliably in the dark, since it doesn't depend on visible-light photography. A generously large recognition zone, roughly 1.3–2.0m from the door, also solves a problem plain fingerprint locks struggle with: a child's faint, not-yet-defined fingerprint, or an elderly parent's fingerprint worn smooth by age, both scan just as reliably as anyone else's face.\u003c\/p\u003e\n\u003ch2\u003eWays to Unlock\u003c\/h2\u003e\n\u003cp\u003eSix access methods in total, covering biometric, digital and physical entry:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3D face recognition\u003c\/strong\u003e – unlocks in about a second using structured-light facial mapping, distinct from a simple 2D camera and far harder to fool with a photo.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApple Home Key\u003c\/strong\u003e – tap your iPhone or Apple Watch via NFC, no need to unlock your phone first.

Just as importantly for a face-scanning device: your facial data is processed and stored locally on the lock itself, never uploaded to any cloud server. That matters twice over — it means there's no remote database of your family's faces for anyone to breach, and it keeps the lock in line with Singapore's Personal Data Protection Act (PDPA).\u003c\/p\u003e\n\u003ch2\u003eBattery \u0026amp; Power\u003c\/h2\u003e\n\u003cp\u003eA rechargeable lithium battery lasts around 4 months per charge — shorter than a simple keypad lock, which is the trade-off for running a camera and face-mapping processor. To offset that, every D200i we sell includes a bonus second battery (worth $80), so you can swap in a fully charged spare in about thirty seconds and recharge the first one at your leisure, rather than the lock ever being out of action while you wait for it to charge. And if both batteries ever run out at once, the door still opens with the included mechanical key, or with a quick top-up from a power bank via the USB-C port.\u003c\/p\u003e\n\u003ch2\u003eSmart Home \u0026amp; Doorbell\u003c\/h2\u003e\n\u003cp\u003eThe D200i integrates with Apple HomeKit and Google Home, and includes a built-in doorbell button on the exterior panel that pushes a notification straight to your phone through the Aqara app when someone presses it — one less separate doorbell device to install and wire up. Paired with other Aqara smart home devices, walking in the door can trigger the lights to switch on and the air-con to adjust automatically, while leaving can arm your cameras and switch off appliances you've designated — no extra button presses required.\u003c\/p\u003e\n","brand":"Aqara","offers":[{"title":"Default Title","offer_id":41098560569440,"sku":"","price":1059.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/4182\/6400\/files\/AqaraD200ICover.webp?v=1776166382"},{"product_id":"aqara-a100","title":"Aqara A100 Smart Door Lock","description":"\n\u003ch2\u003eA Straightforward, Well-Built Everyday Smart Lock\u003c\/h2\u003e\n\u003cp\u003eThe Aqara A100 focuses on doing the fundamentals well: a fast handle-mounted fingerprint scanner, six ways to get in, and genuine multi-point locking, all backed by Apple HomeKit and Google\/Alexa support. If the D100 and D200i are about adding new capabilities like cameras and face recognition, the A100 is about making the everyday basics — unlocking the door, securing it properly, and not running out of battery — as reliable as possible.\u003c\/p\u003e\n\u003ch2\u003eWays to Unlock\u003c\/h2\u003e\n\u003cp\u003eSix access methods are supported: fingerprint, PIN code (permanent, one-time or periodic), NFC tag, mechanical key, the Aqara app, and Apple Home Key — giving every household member and every situation (deliveries, cleaners, guests) an appropriate access method. A one-time password that expires after a single use is ideal for a delivery or a repairman who only needs access once; a periodic password that only works on, say, Tuesday mornings suits a weekly cleaner without you needing to remember to disable it afterwards.\u003c\/p\u003e\n\u003ch2\u003eInstant, One-Motion Entry\u003c\/h2\u003e\n\u003cp\u003eThe fingerprint reader sits right in the handle: a roughly 0.3-second scan and a roughly 0.5-second unlocking cylinder mean the whole sequence, from touch to open, happens in under a second and in a single natural motion — you're not standing at a separate keypad waiting before you can even reach for the handle. Apple Home Key works the same way for iPhone and Apple Watch owners: hold your device near the lock for an instant tap-to-unlock in Express Mode, or switch to a more secure mode that requires Face ID or a passcode first.\u003c\/p\u003e\n\u003ch2\u003eMulti-Point Locking\u003c\/h2\u003e\n\u003cp\u003eLifting the handle engages every bolt in the door simultaneously — one door bolt, three main lock bolts and a master lock bolt — rather than relying on a single latch or a single deadbolt point. This is the same principle behind traditional multi-point mortise locks used on higher-security doors: more engagement points along the door frame means more resistance to prying or forcing the door at any single weak spot, which is a meaningfully different security proposition to a basic single-bolt smart lock. Damage sensors on the front panel flag tampering attempts, and the lock includes electromagnetic shielding against the kind of signal-interference attacks that can trip up less protected electronic locks.\u003c\/p\u003e\n\u003ch2\u003eFire-Rated for HDB Doors\u003c\/h2\u003e\n\u003cp\u003eThe A100 is fire-rated and suitable for installation on HDB fire-rated doors, so upgrading to a smart lock doesn't put you out of compliance with local building requirements — a real concern in Singapore, where many HDB main doors carry a fire-rating that certain hardware modifications can compromise if you're not careful about what you install.\u003c\/p\u003e\n\u003ch2\u003eBattery \u0026amp; Power\u003c\/h2\u003e\n\u003cp\u003eEight AA batteries deliver up to 18 months of battery life on typical daily use — among the longest runtimes in the Aqara lineup, since the A100 doesn't need to power a screen, camera or rechargeable pack the way the camera-equipped models do. In practice that means you're looking at roughly one battery change every year and a half rather than every few months, which matters if you'd rather not think about the lock at all once it's installed. And even with the batteries fully depleted, the mechanical key or a USB-C power bank always gets you back inside.\u003c\/p\u003e\n\u003ch2\u003eSmart Home Integration\u003c\/h2\u003e\n\u003cp\u003eWorks over Zigbee 3.0 and Bluetooth, with support for Apple HomeKit and Home Key alongside Google Assistant, so it fits into either ecosystem without needing a separate bridge for basic automation — useful if your household is split between iPhone and Android users, or you're not sure yet which smart home platform you'll standardise on.
