Aqara Smart Video Doorbell G4

Real-World Performance

The Aqara G4 is the only battery-powered doorbell on the market with full HomeKit Secure Video support, and that single fact drives most of the buying decision. MacRumors, AppleInsider, and TechRadar all converge on the same conclusion: if you live in HomeKit you buy this, full stop. The 1080p HDR camera with a 162 degree wide-angle lens is not class-leading on pure pixel count, but the HomeKit integration goes deeper than any competitor. Face recognition runs on-device and integrates directly with Home app automations, so you can trigger scenes when a specific person rings the doorbell.

Audio and night performance are workable but not exciting. The speaker output is described by MacRumors as mediocre for clarity, and the IR night vision is competent without being a standout. Where the G4 separates from the field is the response time and reliability of HomeKit notifications, which feel meaningfully more native than the Home app integrations bolted onto competitors that primarily use their own apps.

Setup and Software

Setup runs through the Home app with the same QR-code pairing flow as any HomeKit accessory, plus a brief enrollment in the Aqara Home app for firmware updates and local face recognition training. The included chime repeater plugs into any indoor outlet and pre-pairs with the doorbell out of the box. The whole process takes about 15 minutes for a battery install. Hardwiring is supported via the same terminals at 12 to 24 VAC or 8 to 24 VDC, which trickle-charges and removes the AA battery rotation entirely.

HomeKit Secure Video storage runs through your existing iCloud+ plan with no separate Aqara subscription. The 50 GB iCloud+ tier supports one HomeKit Secure Video camera, the 200 GB tier supports up to five, and the 2 TB tier covers unlimited. Local recording to a microSD card up to 512 GB also runs in parallel for redundancy. That combination of HomeKit Secure Video plus local microSD is unique in this roundup.

Build Quality and Design

The G4 has a notably more refined design than the chunkier Eufy E340, with a slim rectangular profile and the chime puck designed to fit a standard outlet. The downside is the build feels lightweight in hand, and MacRumors notes the plastic construction would not survive a serious drop. The IPX3 weather rating is the weakest in this roundup and rates only for vertically falling water at angles up to 60 degrees from vertical. In practice that means light to moderate rain is fine but driving sideways rain or a porch that catches storm spray may stress the unit. A covered porch overhang is recommended.

Mounting includes both adhesive backing and a screw-in bracket, plus optional angle wedge accessories sold separately for porches where the doorbell sits at an angle to the approach path. The included chime is pre-paired and cannot be replaced separately, so a broken chime means a full replacement order.

Where It Falls Short

Four issues to know going in. The 1080p resolution is dated compared to 2K and 1536p competitors, which matters less than the spec sheet suggests for a doorbell at typical visitor distance but does show up when you zoom into archived events. The 16:9 framing means the bottom of the field of view sits at roughly mid-shin height, so a package dropped right at the door may sit below the frame on a shallow porch. The 6 AA batteries last only about 4 months and are not rechargeable in stock form, so you are buying replacements 3 times a year unless you hardwire. The IPX3 rating is the weakest in this roundup and the G4 should not be installed exposed to driving rain.

Who It's Best For

Buy this if you are inside the Apple ecosystem and you want HomeKit Secure Video for your doorbell. There is no other meaningful choice in this category for that use case. The 119 dollar price is the lowest in the roundup and the HomeKit integration is the deepest. On-device face recognition feeding into Home app automations unlocks scenarios that no other doorbell in this list can match.

Skip it if you do not use HomeKit, in which case every other product on this list outperforms it on the metrics you actually care about. The Eufy E340 is a better subscription-free pick for Alexa and Google households, the Ring Battery Doorbell Plus is the better polished battery option, the Google Nest Doorbell Wired 2nd Gen is the better Google Home pick, and the Arlo Essential is the better wide-FOV option.

Value at This Price

At 119 dollars the G4 is the cheapest doorbell in this roundup, and the HomeKit Secure Video integration alone justifies the buy for Apple households. The only ongoing cost is iCloud+ at 2.99 a month for 200 GB, which most Apple Photos and iCloud Drive users already pay for other reasons. Compare that to Ring Protect at 4.99 a month or Arlo Secure at 7.99 a month and the total cost of ownership math swings decisively in the G4's favor over a multi-year window. The trade-off is the lower IPX3 rating and 1080p resolution, both of which are tolerable for the right install.

The 6 AA battery cost over a typical 4-month replacement cycle adds roughly 8 to 12 dollars per year in lithium AA cells, or essentially zero if you hardwire the unit. Buyers with existing low-voltage doorbell wiring should default to the wired install for the trickle-charge convenience and to remove the AA rotation entirely. The included chime puck plugs into any standard outlet and pre-pairs out of the box, removing the need for a HomeKit hub purchase.

Long-Term Durability

The G4 launched in early 2023 and has held up well across a multi-year review window. Aqara has shipped consistent firmware updates including HomeKit Secure Video performance improvements and the on-device face recognition feature added in 2024. The lightweight plastic construction is the only meaningful long-term concern flagged by MacRumors, who noted that a serious drop during installation or repositioning could crack the housing. The IPX3 weather rating is the lower bound for an outdoor doorbell and the G4 should be installed under a porch overhang or storm-door enclosure rather than fully exposed to driving rain.
