Aqara makes two wired smart video doorbells that look similar but solve different problems. The Aqara Doorbell Camera Hub G410 (S$309) is an all-in-one doorbell that also works as a smart-home hub, while the Aqara Doorbell Camera G400 (S$249) is a focused video doorbell that leans on a hub you already own. Both are sold by PassionHome as an Authorised Aqara Dealer in Singapore.
The quick verdict: choose the G410 if you want one device to be both your doorbell and your smart-home hub, or you need battery-powered flexibility. Choose the G400 if you already have a hub and want Power over Ethernet, a published IP65 weather rating, faster Wi-Fi 6 and a lower price. Here is the full comparison.

| A focused video doorbell when you already own a hub, for less | G400 |
The Aqara Doorbell Camera G400 in brief
The Aqara Doorbell Camera G400 is a wired-only 2K video doorbell. It records at 1536 × 2048 in a tall 3:4 aspect ratio with a 165° diagonal view — built to show a caller’s face and any parcel on the floor in one frame — and uses 940nm infrared LEDs for invisible night vision. It runs on Power over Ethernet (IEEE 802.3af) or existing 8–24V doorbell wiring, is rated IP65 against rain and dust, and detects motion, people and zone intrusions with on-device AI. It is not a smart-home hub.
The Aqara Doorbell Camera Hub G410 in brief
The Aqara Doorbell Camera Hub G410 is a doorbell and a smart-home hub in one. It is a Matter Controller, Thread Border Router and Aqara Zigbee hub — Aqara’s own description is that it “doubles as a hub for Aqara Zigbee devices and practically any Matter device on the market, no additional hub required.” It records 2K video (up to 1536p) across a wide 175° 4:3 view with an f/1.8 lens, uses an mmWave radar presence sensor with on-device face recognition, and can run on either 12–24V wiring or 6 × AA batteries for up to about five months.

The big difference: hub or no hub
This is the decision that matters most. The Aqara Doorbell Camera Hub G410 has a built-in Matter Controller, a Thread Border Router and an Aqara Zigbee hub, so the doorbell itself can run your smart-home logic and connect your Aqara sensors, switches and locks — no separate hub required. It also bridges those Aqara Zigbee devices to Apple Home, Google Home, Alexa and SmartThings through Advanced Matter Bridging.
The Aqara Doorbell Camera G400 does none of that. It is a camera doorbell with no Zigbee, Thread or Matter hub functionality. It still works with Apple HomeKit Secure Video, streams to Alexa, Google Home and SmartThings displays, and integrates with Home Assistant over RTSP and ONVIF — but if you want to run Aqara Zigbee devices, you will need a separate hub such as the Aqara Hub M200. If you already own a hub, that is no loss, and you save S$60.
Power and installation flexibility
The two doorbells take opposite approaches to power. The Aqara Doorbell Camera Hub G410 can run on 6 × AA batteries (up to ~5 months) for a wire-free install, or on 12–24V doorbell wiring — but note that 24/7 continuous recording is only available in wired mode, and the G410 has no PoE. The Aqara Doorbell Camera G400 is wired-only and battery-free, but it adds Power over Ethernet (IEEE 802.3af), so a single network cable can carry both power and data; it also works on 8–24V doorbell wiring.
For wired installs that need a transformer, PassionHome stocks a compatible 12V doorbell transformer. Both doorbells include their own chime in the box, and neither uses an existing mechanical chime.
Weatherproofing for Singapore
Here the cheaper doorbell actually has the edge on paper. The Aqara Doorbell Camera G400 carries a published IP65 rating against rain and dust. Aqara does not publish an IP code for the Aqara Doorbell Camera Hub G410, so for an exposed entrance a weatherproof case is recommended. In practice, both are best mounted under an HDB lift-lobby, corridor awning, condo entrance or landed-property porch rather than in fully open rain.
Detection, video and AI
The Aqara Doorbell Camera Hub G410 uses an mmWave radar presence sensor for fewer false alerts and adds on-device face recognition, so it can greet recognised faces locally without the cloud. The Aqara Doorbell Camera G400 relies on on-device AI for motion, person and zone-intrusion detection, while its face, package and vehicle recognition runs in the cloud via a HomeGuardian plan.
Both shoot 2K video. The Aqara Doorbell Camera G400 favours a tall 3:4, 165° view that captures a visitor head to toe and a parcel on the ground, and it runs on faster Wi-Fi 6. The Aqara Doorbell Camera Hub G410 offers a wider 175° 4:3 view with an f/1.8 lens, on Wi-Fi 5. Both cap resolution at 1200p when paired to Apple HomeKit Secure Video.
Smart-home support and storage
Both doorbells work with Apple HomeKit Secure Video (an iCloud+ plan and an Apple home hub are required), stream a live view to Google Home, Alexa and SmartThings displays, and integrate with Home Assistant. The G410 adds the full hub role on top. For storage, both record to a microSD card of up to 512 GB, back up to a NAS, and offer end-to-end-encrypted HomeGuardian cloud; the G400 additionally supports ONVIF/NVR, while the G410’s 24/7 continuous recording requires wired mode.
When to choose the G410
- You want one device that is both a video doorbell and a Matter / Thread / Zigbee smart-home hub
- You need a battery-powered install (no wiring) for up to ~5 months
- You want mmWave radar presence detection and on-device face recognition
- You want the widest 175° view with an f/1.8 low-light lens
When to choose the G400
- You already own a smart-home hub and just need a great video doorbell for less
- You want a Power-over-Ethernet install with a single cable
- You want a published IP65 weather rating
- You want Wi-Fi 6 and a tall 3:4 head-to-toe view for parcels at the door

Frequently asked questions
What is the main difference between the Aqara G410 and G400?
The G410 is a video doorbell that is also a smart-home hub — a Matter Controller, Thread Border Router and Aqara Zigbee hub in one. The G400 is a video doorbell only. If you want the doorbell to also run your Aqara and Matter devices, choose the G410; if you already have a hub, the G400 covers the doorbell for S$60 less.
Can the G400 work as a smart-home hub like the G410?
No. The G400 has no Zigbee, Thread or Matter hub functionality. It works with Apple HomeKit Secure Video, Alexa, Google Home and SmartThings displays, and Home Assistant — but to run Aqara Zigbee devices you would need a separate hub such as the Aqara Hub M200.
Which one can run on battery?
Only the G410, on 6 × AA batteries for up to about five months. The G400 is wired-only and battery-free, powered by PoE or existing 8–24V doorbell wiring. Note the G410’s 24/7 continuous recording only works in wired mode.
Which is better for Singapore weather?
The G400 has a published IP65 rating against rain and dust. Aqara publishes no IP code for the G410, so a weatherproof case is recommended for exposed installs. In practice both are best mounted under an HDB lift-lobby, corridor awning, condo entrance or porch.
Do both work with Apple Home?
Yes. Both support Apple HomeKit Secure Video (an iCloud+ plan and an Apple home hub are required, and resolution is capped at 1200p within Apple Home). Both also stream to Google Home, Alexa and SmartThings displays and integrate with Home Assistant.
Which has the better camera?
Both are 2K. The G400 has a tall 3:4, 165° view that captures visitors head to toe plus parcels on the ground, and runs on Wi-Fi 6. The G410 has a wider 175° 4:3 view, an f/1.8 lens and mmWave radar with on-device face recognition. They have different strengths rather than one clearly winning.
Do I need a subscription for either?
No for local features — both record to a microSD card and run local detection with no subscription. A HomeGuardian plan (free trial included) adds cloud AI and cloud storage on both. The G410’s cloud face recognition is on-device; the G400’s face, package and vehicle recognition is cloud-based via HomeGuardian.
Is there a local warranty?
Yes. Both carry a 24-month Aqara manufacturer warranty serviced by the Aqara Service Center. PassionHome is an Authorised Aqara Dealer — WhatsApp +65 9051 7063 for help choosing or installing.
The verdict
There is no single winner here — it depends on what else is in your smart home. Choose the Aqara Doorbell Camera Hub G410 (S$309) if you want one device to be your doorbell and your Matter / Thread / Zigbee hub, or you need a battery install. Choose the Aqara Doorbell Camera G400 (S$249) if you already have a hub and want Power over Ethernet, a published IP65 weather rating, Wi-Fi 6 and a lower price.
