Aqara Doorbell Camera G400 Wired/PoE 2K Vertical HD with Chime, Wi‑Fi 6 & HomeKit Secure Video

The Aqara Doorbell Camera G400 is a weatherproof wired/PoE video doorbell that delivers vertical 2K HD footage, HomeKit Secure Video support, local AI detections, and a built-in chime for reliable, private home monitoring.

The G400 combines pro-level connectivity with simple installation: use existing 8–24V wiring or PoE for steady power, connect via Wi‑Fi 6 (2.4/5GHz), and choose local or cloud workflows through HomeKit Secure Video, Aqara Home, or other ecosystems. Designed to reduce false alerts and capture a head‑to‑toe view, this doorbell is built for everyday security, package monitoring, and clear two‑way conversations.

How does the G400 capture a full head‑to‑toe view?

The G400 uses a 165° ultra‑wide lens with a 3:4 aspect ratio to record vertical scenes that show packages at the doorstep and faces clearly. Its 2K sensor preserves detail for identification, and near‑invisible 940nm infrared LEDs maintain night visibility without visible glows.

• 2K HD resolution (1200p on HomeKit)
• 165° field of view for vertical framing
• 940nm infrared illumination for discreet night recording
• Optimized 3:4 aspect ratio to include ground-level packages

What power and network options are available for installation?

Installers can pick hardwired AC/DC (8–24V) or PoE for a stable, low‑latency connection; Wi‑Fi 6 compatibility (2.4/5GHz) lets the G400 fit modern home networks while supporting WPA3 security. These options simplify upgrades and improve continuous recording reliability.

• Supports Power over Ethernet (PoE) and existing doorbell wiring
• Wi‑Fi 6 on both 2.4GHz and 5GHz bands for faster streaming
• WPA3 network security for safer connections
• Plug‑in chime included for indoor alerts

How does the G400 keep alerts accurate and private?

Local AI runs on the device to recognize people, detect zone intrusions, and reduce false alarms without sending raw video to external servers. When paired with HomeKit Secure Video, recordings are encrypted and can use iCloud storage; local microSD and NAS backups provide extra redundancy.

• On‑device person recognition and zone-based detection
• HomeKit Secure Video compatible (requires iCloud+ and home hub)
• 24/7 local recording to microSD (up to 512GB) and SMB NAS backup
• Custom quick replies and a voice‑changing intercom for safe interaction

Which smart home platforms and integrations does it support?

The G400 is designed to work across major ecosystems: HomeKit Secure Video for Apple users, plus Alexa, Google Assistant, SmartThings, and professional ONVIF/RTSP connections for NVRs. Aqara Home integration expands automations and multi‑device flows for a cohesive entryway experience.

• Apple HomeKit Secure Video for encrypted Apple ecosystem recording
• Works with Alexa, Google Assistant, and SmartThings
• RTSP/ONVIF support for third‑party NVR and advanced setups
