Aqara G350 vs G400: 4K Matter Camera or 2K PoE Doorbell?

Camera Hub G350 and Doorbell Camera G400 (Wired) belong to Aqara's 2026 camera generation but serve different security layers. G350 is primarily an indoor PTZ camera that also functions as a hub/controller, while G400 is a wired entry doorbell focused on PoE, continuous recording and NVR/NAS integration.

Quick comparison: G350 vs G400

G350: dual-lens 4K + 2.5K and 9× hybrid zoom

The source article records G350 using a 3840×2160 wide lens and 2560×1440 tele lens, f/1.6 aperture, 940 nm infrared and up to 9× hybrid zoom. PTZ provides 360° observation, presets and person/pet tracking, with Aqara documenting up to 30 preset angles.

G350: Matter Camera with platform-dependent capabilities

Aqara introduces G350 as a Matter-certified camera and also as an Aqara Zigbee Hub, Matter Controller and Matter Bridge. Matter Camera support at platform level still varies; PTZ, AI, zoom, video history or every capability available in Aqara Home should not be assumed to appear fully in Apple Home, Google Home or another Matter platform.

G350: understand local storage and NAS correctly

G350 supports microSD up to 512 GB and 24/7 recording. The source article records Aqara describing NAS as a transfer/backup workflow from recordings stored on microSD, so it should not be presented as direct-to-NAS recording without first checking the current firmware and storage workflow.

G400: 2K head-to-toe view, PoE and IP65

G400 records at 1536×2048 in a 3:4 ratio with a 165° diagonal field of view, suited to seeing both a visitor's face and the package area. The source article records IP65, IEEE 802.3af PoE or 8–24V AC/DC power and notes that the device does not use a battery as its main operating power source.

Reusing existing doorbell wiring requires transformer checks

The source article records Aqara guidance to verify both transformer voltage and VA capacity. Examples listed are AC24V at a minimum of 12VA, AC18V at a minimum of 18VA and AC16V at a minimum of 16VA. 8–10V supplies are marked as not recommended due to loss and power limits. The article also records that G400 is not intended to work with an existing traditional chime through the manufacturer's normal wiring method.

G400: 24/7 recording, SMB NAS and ONVIF

G400 supports microSD up to 512 GB for continuous recording. The source article records SMB NAS backup and ONVIF support for compatible NVR/software systems, with Aqara noting that 24/7 recording and NAS support require a microSD card installed in the device.

Local AI and HomeGuardian should be separated

The source article records local processing on G400 for motion detection, person detection and zone intrusion. Cloud AI functions such as face, package and vehicle recognition or search/summary belong to HomeGuardian service conditions and should not all be grouped under the label 'local AI'.

Apple Home has its own resolution limits

According to the source article, Aqara documents G350 at up to 1080p in Apple Home and G400 at up to 1200p. Native sensor resolution is not the same as the resolution exposed in every ecosystem. HomeKit Secure Video also depends on the applicable iCloud+ and Apple Home Hub requirements.

Which device should you choose?

• Choose G350 when indoor PTZ/zoom, local AI and hub/controller functions are priorities.
• Choose G400 when the main entrance, PoE/hardwired power, 24/7 recording and ONVIF/NAS are priorities.
• Use both when you want to separate perimeter/entry security from indoor observation.
• For Apple Home, design around the practical HKSV limits rather than only the native sensor resolution.
• If G400 reuses existing doorbell wiring, measure both voltage and VA before installation.
• Record the exact regional model/SKU in the BOQ.
