3D Face Recognition \u0026 Apple Home Key","description":"\n\u003ch2\u003eThe Smart Lock That Recognises Your Face\u003c\/h2\u003e\n\u003cp\u003eThe Aqara D200i brings iPhone-style 3D facial recognition to your front door, alongside Apple Home Key and a full set of conventional access methods. It's built for households that want a genuinely touchless, hands-full-of-groceries entry experience without giving up backup options for the days that technology doesn't cooperate.\u003c\/p\u003e\n\u003ch2\u003eHow the Face Recognition Actually Works\u003c\/h2\u003e\n\u003cp\u003eMost budget \"facial recognition\" locks use a simple 2D camera, which can sometimes be fooled by a printed photo held up to the lens. 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":"gateman-sp122","title":"Gateman SP122 Digital Door Lock","description":"\n\u003ch2\u003eA Simple, App-Free Digital Lock\u003c\/h2\u003e\n\u003cp\u003eThe Gateman SP122 is built for households that want a reliable digital lock without an app, Wi-Fi, or any connectivity dependency — just PIN and card access that works the same way every time, with nothing to update, pair or reconnect.\u003c\/p\u003e\n\u003ch2\u003eWays to Unlock\u003c\/h2\u003e\n\u003cp\u003ePIN code and RFID card access, with support for multiple card registrations so every household member can have their own rather than sharing one.\u003c\/p\u003e\n\u003ch2\u003eSecurity \u0026amp; Reliability\u003c\/h2\u003e\n\u003cp\u003eAn anti-tamper alarm and wrong-PIN lockout protection guard against tampering and brute-force PIN guessing — enough failed attempts and the keypad temporarily locks out further tries — and the door auto-locks as soon as it closes.
