Aqara Video Doorbell G4

Compiled by SmartHomeWorkflow Research · Aqara · Cameras & Doorbells · ~$99.99 (at time of research, read from Aqara's own storefront structured data for the product's own SKU (DTC-US-EN-G4, $99.99, InStock) rather than from the rendered page — the method rule that exists because this vendor's product pages carry other products' copy and prices. Never treated as a live price. ⚠ The previous figure of $120 was a $20.01 overstatement whose basis was never recorded: it came in on a 2026-07-12 migrated provenance entry whose own note said the original source 'did not record which facts this source actually backed'.)

Compatibility

Protocols: WIFI^[4][5][22]

What it can do^[14]

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[1][6][23]

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

No subscription, and Aqara quantifies the saving in its own product copy: 'Save approximately $60 annually with free cloud storage for up to 7 days of event-based clips, eliminating the need for subscription fees.' Two storage paths ship free — Aqara's own 7-day event cloud, and local microSD in the indoor chime (card not included, up to 512 GB). For Apple households HomeKit Secure Video recording rides an existing iCloud+ plan, which is the buyer's existing storage rather than a camera fee. ⚠ Aqara describes NAS storage as 'planned', not shipped, so it is recorded as a future intention and not as a capability.

Maintenance reality^[5]

• Batteries: AA x6 — expect roughly 4 months per set
• Works without the internet: Partly — some of it keeps working and some of it does not. See the detail below.^[24]
• Battery-powered with chime repeater; HSV needs iCloud+ storage plan

Security updates^[12]

Aqara states its security-update commitment for this model as a period rather than a date: at least 2 years from the launch day (UK-declared — the maker's legal commitment is filed for the United Kingdom). That is a floor measured from a starting point the manufacturer sets — a launch or a purchase — rather than a fixed end date, so it cannot be placed on a calendar here. We record the commitment as the manufacturer states it, in our words, rather than converting it into a date it did not give. This is a published commitment, not a gap in our research.

A signed per-product regulatory declaration exists for this exact model and it still does not yield a date, which is why updatesUntil is null rather than unfilled. Aqara's UK Statement of Compliance names Product 'Smart Video Doorbell G4', Model name 'SVD-C01, SVD-C02', issued April 9, 2024, and states: 'the defined support period for the product above is at least 2 years from the launch day.' That is a FLOOR expressed relative to launch, not a calendar date — and this model launched 2023-03-23 on Aqara's own policy table, so the only commitment Aqara has published for it elapsed before this reading. Recorded verbatim rather than converted: turning 'at least 2 years from launch' into a date would invent both a precision and a direction the vendor did not give (a floor is not an expiry). ⚠ A SECOND AQARA DOCUMENT DISAGREES AND RANKS LOWER, named here rather than hidden: Aqara's 2024-08 Product Security Support Policy table gives this model an 'End of security update support' of 2026-06-30. Method note 69 puts a signed per-product regulatory declaration above a vendor policy table, so the declaration governs — and the practical difference matters to a reader, because 2026-06-30 is already in the past while the declared period is not. The same declaration wording appears on Aqara's Water Leak Sensor record, so this is a vendor pattern rather than a one-off. ⊕ REGION: UK — the declaring document is a UK PSTI Statement of Compliance, filed under the Product Security and Telecommunications Infrastructure Act. The scope is the filing's own: this is a promise made for the United Kingdom, and it is printed that way so a buyer elsewhere is never told a British legal commitment covers their unit (S-1b).

The catch

1080p only — resolution trails the 2K competition.

Who it's for

Apple households wanting HomeKit Secure Video without a Ring-style subscription.
