Genuine Singapore stock with local warranty service through the Aqara Service Center. 2K video that captures face to floor The G400 records at 2K resolution (1536 × 2048) with a 165° diagonal field of view. Its tall 3:4 aspect ratio is built for doorways — you see a caller’s face and any package left on the ground in a single frame. Subtle 940nm infrared LEDs deliver full high-definition video in complete darkness without a visible glow, and flexible brightness tuning keeps faces and parcels clear in tricky lighting. Smart detection — local AI and optional cloud AI Powered by local AI, the G400 detects motion, people and zone intrusions in real time, entirely on the device and without relying on the cloud — so the core alerts work with no subscription. Add a HomeGuardian plan (a free 3-month trial is included; a paid plan is required afterwards) and cloud AI extends this to recognise faces, animals, packages and vehicles, plus AI video search and richer notifications. Works with your smart home The G400 fits into the ecosystem you already use: Apple HomeKit Secure Video — works directly with the Apple Home app. HomeKit Secure Video needs an iCloud plan and an Apple home hub, and the resolution is capped at 1200p within Apple Home. Google Home, Amazon Alexa and SmartThings — stream a live view of your doorstep to compatible smart displays. Home Assistant — full integration via RTSP and ONVIF for local-first setups. Aqara Home — unlock a paired smart lock straight from the live view, and stream to compatible Aqara screens. Wired power — PoE or your existing doorbell wiring The G400 is battery-free and offers two wired options. The simplest is Power over Ethernet (IEEE 802.3af, 48V), which carries power and data over a single network cable. Alternatively it connects to existing low-voltage doorbell wiring across a wide 8–24V AC or DC range (8–24V AC at 1.3A, or 8–24V DC at 0.8A). For AC wiring, Aqara recommends a transformer rated at least 12VA (a 24V/≥12VA, 18V/≥18VA or 16V/≥16VA supply is recommended; 8–10V supplies are not recommended). One important note for Singapore homes: the G400 does not work with an existing traditional mechanical chime. Instead it includes its own plug-in Chime unit in the box — you can use the doorbell with or without it, and ringtone, volume and the number of rings are all adjustable. If you are unsure whether your entrance has suitable doorbell wiring, WhatsApp our team and we will help you plan the install. Storage your way — local, NAS, NVR or cloud microSD up to 512 GB — 24/7 continuous local recording (card not included). NAS backup — automatically back up local recordings to an SMB NAS server. ONVIF / NVR — works with standard NVRs and ONVIF-compliant software for interoperability. HomeGuardian cloud — store recordings in the cloud for up to 90 days with end-to-end encryption (paid plan after the free trial). Privacy and security built in Privacy masking — block out parts of the image so they are never recorded. Voice modification — disguise your voice during two-way conversations. Tamper alarm — a loud alarm triggers if someone tries to remove or interfere with the doorbell (off by default). End-to-end encryption — cloud recordings on a HomeGuardian plan are end-to-end encrypted. Installation in Singapore The G400 is an outdoor-rated (IP65) doorbell built to handle Singapore’s rain and humidity, with an operating range of −20°C to 50°C. The box includes a mounting plate, a 15° wedge for angling the view across a corridor or gate, both adhesive and screw-mount options, an extension wires kit and a mounting hole template. Wiring into existing 8–24V doorbell circuits or a PoE line is best done by an electrician if you are not comfortable working with low-voltage wiring; the camera setup itself is done in the Aqara Home app. If your estate is running an Aqara group buy, a significant discount applies when your estate unlocks.
