Ring charges you $100 a year to watch recordings of your own front door. Let that sink in. You buy their hardware, you mount it on your house, it records your visitors — and then Ring holds the footage hostage behind a subscription. Aqara just dropped the Doorbell Camera G400 at $99.99, and in this Aqara Doorbell Camera G400 review, I'm going to explain why it makes Ring's entire business model look like a shakedown. Two-K resolution, HomeKit Secure Video with free encrypted cloud storage, on-device AI, and zero monthly fees. Ever.
One of these companies respects you. The other one has "snitching" in our headline about them.
Why Another Doorbell Camera?
I know what you're thinking. "Another doorbell camera review? Didn't we solve this already?" No. We didn't. Because the doorbell camera market has been a protection racket for years, and most people don't realize it.
Here's how Ring, Google, and every other major player designed their business model: sell you a camera for $100-$200, then charge you $4-10 per month forever to actually use the thing you bought. Want to see who was at your door while you were at work? Pay up. Want to know if that was a person or a car? Pay up. Want to save clips for more than a few hours? Pay. Up.
Ring Protect Basic costs $3.99/month. Ring Protect Plus — which you need if you have more than one Ring device — runs $10/month or $100/year. Over three years, that $150 Ring doorbell actually costs you $250-$450. And what do you get for that premium? A company that hands your footage to law enforcement without a warrant.
The Aqara Doorbell Camera G400 launched on March 17, 2026 at $99.99. It stores video clips for free through Apple HomeKit Secure Video or on a local microSD card. There is no subscription tier. There is no "premium" unlock. You pay once, you own the camera and everything it records. That's how this should have worked from the beginning.
What You Get for $100
Let's talk specs, because they matter here. Aqara didn't cut corners to hit this price point — they cut the subscription.
The G400 shoots in 2K resolution (2304 × 1296), which is meaningfully sharper than the 1080p you'll find on most budget doorbells and even matches some cameras twice its price. The field of view is 165 degrees with a 3:4 aspect ratio, which is the real headline feature. That portrait-style view means you see everything from a visitor's face down to packages on the ground — no more mystery deliveries sitting just below the camera frame.
Connectivity is dual-band Wi-Fi 6 (802.11ax), which is a spec I care about more than most people realize. Wi-Fi 6 isn't just "faster internet." It's better at handling interference, maintaining stable connections at range, and managing bandwidth in congested home networks. Your doorbell camera sits at the edge of your Wi-Fi coverage. Wi-Fi 6 matters here.
For power, you've got two options: PoE (Power over Ethernet) or traditional 16-24V AC low-voltage wiring — the same transformer setup that powers most existing wired doorbells. If you already have a wired doorbell, this is likely a drop-in replacement.
On-device AI handles person, package, vehicle, and animal detection. That processing happens locally on the camera — not in some data center in Virginia. This means faster notifications, fewer false alerts from every leaf that blows across your porch, and no cloud dependency for basic intelligence.
You also get two-way audio with noise cancellation, infrared night vision, and an IP65 weather resistance rating.
Now compare that to the Ring Video Doorbell 4 at $149.99. You're paying 50% more for 1536p resolution (slightly less than 2K), no local processing of any intelligence features without a subscription, and the privilege of funding Ring's surveillance partnership program. I genuinely don't understand why anyone would choose Ring at this point unless they're already locked into the Alexa ecosystem so deep they can't escape.
HomeKit Secure Video — The Privacy Advantage
This is the section that matters most, and it's where the G400 becomes more than just a "good budget camera." It becomes a statement about what kind of smart home you want to live in.
HomeKit Secure Video (HKSV) is Apple's framework for security cameras. Here's what it does:
End-to-end encryption. Your video is encrypted on the camera before it leaves your network. Apple can't see it. Aqara can't see it. Nobody can see it except devices signed into your iCloud account.
Free iCloud storage. HKSV recordings are stored in iCloud but don't count against your storage quota. You need an iCloud+ plan (starting at $0.99/month for 50GB, which you probably already have), but the video storage itself is free. Unlimited cameras, unlimited clips.
On-device facial recognition. If you have an Apple TV or HomePod as a home hub, HKSV can identify familiar faces and send you smarter notifications. "Someone is at the door" becomes "Mom is at the door." This processing happens on your home hub, not in a cloud.
Activity zones. Define specific areas of the camera view that trigger recordings, reducing noise from busy streets or sidewalks.
10-day clip history. HKSV stores the last 10 days of motion-triggered clips automatically.
Now compare this to Ring's approach. Ring stores your video on Amazon's servers. Ring has shared footage with over 2,000 law enforcement agencies, sometimes without warrants or user consent. Ring's parent company Amazon has used doorbell footage in employee surveillance. Ring encrypts data in transit, but the default is not end-to-end — meaning Amazon holds the keys.
If you've read our piece on why you should stop paying for Ring Protect, you already know the privacy math here. But it bears repeating: HKSV gives you genuinely private, encrypted, free cloud storage for your security footage. Ring charges you $100/year for the privilege of storing your footage on servers that cops can access.
This alone is enough reason to buy the G400. Everything else is a bonus.
Installation and Setup
Let's get the big caveat out of the way: the G400 is wired only. There's no battery option. You need either:
- Existing doorbell wiring (16-24V AC transformer, which most homes with a wired doorbell already have), or
- Power over Ethernet (PoE), if you've got an Ethernet run to your front door
For homeowners with existing wired doorbells, this is usually a 20-minute swap. Remove old doorbell, connect two wires, mount the G400, scan the QR code in the Aqara Home app, and add it to Apple Home. The app walks you through it.
For renters, this is a dealbreaker. I'm not going to sugarcoat it. If you can't run wires to your front door, this camera isn't for you. There's no battery backup, no solar option, no workaround. If you're renting and want a privacy-first doorbell, you'll need to look at battery-powered alternatives or talk to your landlord about the existing wiring situation.
For homeowners or renters with existing doorbell wiring, though, installation is genuinely straightforward. The PoE option is particularly interesting for anyone building out a new home or doing a renovation — one Ethernet cable handles both power and data, and you get the most reliable possible connection.
The setup process involves two apps: Aqara Home for initial configuration and firmware updates, and Apple Home for day-to-day use with HKSV. Once it's added to Apple Home, you can basically forget Aqara Home exists unless you need to tweak advanced settings.

What It Does Well
After living with the G400, here's what stands out:
The 3:4 Aspect Ratio Is a Game-Changer
I can't overstate how much the portrait-oriented view improves a doorbell camera. Traditional 16:9 cameras give you a wide, cinematic view of your porch — great for watching the sunset, useless for seeing the Amazon package at your feet. The 3:4 ratio captures the full vertical span from a visitor's head to the ground. You see faces AND packages. This should be the standard for every doorbell camera, and it baffles me that some manufacturers still ship 16:9.
On-Device AI Means Fewer False Alerts
The G400's person/package/vehicle/animal detection runs locally on the camera's processor. No cloud round-trip. No subscription required. This means:
- Notifications arrive faster (no server processing delay)
- The camera works even if your internet goes down (clips save to microSD)
- False positives from shadows, rain, and wind are dramatically reduced compared to dumb motion detection
In my testing, the false alert rate was significantly lower than any Ring camera I've used. It's not perfect — a large dog will occasionally trigger a "person" alert — but it's in a different league from Ring's subscription-locked intelligence.
Wi-Fi 6 Actually Matters for Doorbells
Your front door is probably the farthest point from your router in your home. Doorbell cameras are notorious for dropping connections, buffering during live views, and failing to record clips because the Wi-Fi stuttered at the wrong moment. The G400's Wi-Fi 6 support with dual-band capability means it can connect on 2.4GHz for range or 5GHz for throughput. In practice, this translates to faster live view loads and more reliable clip recording.
The Price. Obviously.
$99.99 with no subscription. Let me put this in a table so it really sinks in:
- Year 1 cost with Ring Doorbell 4 + Ring Protect Basic: $199.98
- Year 1 cost with Aqara G400: $99.99
You save $100 in the first year alone. By year three, you've saved nearly $250. That's a second camera.
What It Doesn't Do
No product is perfect, and I'm not going to pretend the G400 is. Here's what's missing:
No Matter Support
The G400 works with HomeKit and the Aqara ecosystem. It does not support Matter, the supposedly universal smart home standard. In practice, this matters less than you'd think — Matter's camera support is still basically vapor in 2026, and most Matter "compatible" cameras just use a companion app anyway. But if you were hoping for Google Home or Samsung SmartThings integration through Matter, you're out of luck.
No Battery Option
I covered this above, but it's worth listing again. Wired-only is a genuine limitation. Battery doorbells exist for a reason — not everyone has doorbell wiring, and not everyone wants to install it.
Apple Ecosystem Only (For HKSV)
The G400's killer feature — free encrypted cloud storage through HKSV — only works if you're in the Apple ecosystem. You need an iPhone, an iCloud+ subscription, and ideally an Apple TV or HomePod as a home hub. If your household runs on Android phones and Google Home speakers, you can still use the G400 through the Aqara Home app with local microSD storage, but you lose the best reason to buy it.
No Thread
The G400 connects via Wi-Fi only. No Thread radio for mesh networking with other smart home devices. For a doorbell camera that needs high-bandwidth video streaming, Wi-Fi is honestly the right call. But Thread would have been nice for future-proofing and deeper HomeKit integration.
Aqara G400 vs Ring Doorbell 4 vs Google Nest Doorbell
Here's the comparison that matters. I'm including the 3-year total cost because that's how you should evaluate any product with a subscription.
| Feature | Aqara G400 | Ring Video Doorbell 4 | Google Nest Doorbell (Wired) |
|---|---|---|---|
| Price | $99.99 | $149.99 | $179.99 |
| Resolution | 2K (2304×1296) | 1536p (2048×1536) | 1080p (1920×1080) |
| Field of View | 165° (3:4) | 160° (head-to-toe) | 145° (3:4) |
| Subscription Cost | $0/year | $39.99-$99.99/year | $0-$79.99/year |
| Local Storage | microSD | No | No |
| Free Cloud Storage | Yes (HKSV) | No (30-day trial only) | 3 hours only |
| End-to-End Encryption | Yes (HKSV) | Opt-in (disables features) | No |
| On-Device AI | Yes (free) | No (requires subscription) | Yes (limited free) |
| Police Footage Sharing | No | Yes | Via warrant |
| Ecosystem | Apple HomeKit | Amazon Alexa | Google Home |
| Wi-Fi | Wi-Fi 6 (dual-band) | Wi-Fi 6 (dual-band) | Wi-Fi (dual-band) |
| Power Options | PoE / 16-24V AC | Battery / Wired | Wired only |
| 3-Year Total Cost | $99.99 | $269.96 - $449.96 | $179.99 - $419.96 |
Read that last row again. The Ring Doorbell 4 can cost you up to $450 over three years when you factor in the subscription that makes it actually functional. The Aqara G400 costs $99.99. Period. Forever.
The Google Nest Doorbell lands somewhere in the middle — it offers limited free features, but the good stuff (familiar face detection, 24/7 recording) requires Nest Aware at $6.99/month or $79.99/year. And Google's privacy record is... Google's privacy record.

Who Should Buy This
Buy the Aqara G400 if you are:
- An Apple HomeKit household (iPhone + Apple TV or HomePod)
- A homeowner with existing doorbell wiring or willingness to install it
- Someone who values privacy and wants end-to-end encrypted footage
- Tired of subscriptions and wants a one-time purchase that works forever
- Looking for the best value doorbell camera in 2026
Do NOT buy the Aqara G400 if you are:
- A renter who can't modify wiring (look at battery options instead)
- Android-only with no Apple devices (you'll lose HKSV, the main selling point)
- Deep in the Alexa ecosystem and want Ring integration with Echo Show, Alexa routines, etc.
- Wanting a battery-powered doorbell for flexible placement
- Needing Matter or Google Home integration
This isn't a camera for everyone. It's a camera for Apple households who want privacy, quality, and zero recurring costs. For that audience, it's not just the best option — it's the only option that makes sense.
The Bottom Line
The Aqara Doorbell Camera G400 is the most important doorbell camera released in years, and not because of its specs — although 2K resolution, 165° FOV, Wi-Fi 6, and on-device AI at $99.99 would be impressive regardless. It's important because it proves that the subscription model dominating home security is a choice, not a necessity.
Ring could offer free local storage. Ring could process AI on-device. Ring could encrypt footage end-to-end so cops can't access it without your permission. Ring chooses not to, because subscriptions are more profitable than respecting their customers.
Aqara chose differently. For $100, you get a doorbell camera that outspecs Ring's $150 offering, stores footage for free, encrypts everything, and will never, ever ask you for another dollar. If you're in the Apple ecosystem, this is the doorbell camera to buy in 2026. Full stop.

🛒 Buy or Don't Buy?
BUY IT if you're an Apple HomeKit household with doorbell wiring. This is the best-value doorbell camera in 2026 and it isn't close. You'll save $250+ over three years compared to Ring, get better resolution, better privacy, and never pay a subscription.
DON'T BUY IT if you're a renter without wiring, an Android household, or deeply invested in Alexa/Google Home. The G400 is a fantastic camera trapped inside Apple's walled garden — if you're not already inside those walls, the HKSV advantage disappears.
Frequently Asked Questions
Q: Does the Aqara G400 work without HomeKit?
A: Yes, the Aqara G400 works without HomeKit through the Aqara Home app on both iOS and Android. You can view live feeds, receive motion alerts, and manage recordings entirely within the Aqara ecosystem. However, HomeKit Secure Video integration is one of its strongest features, so you'd be leaving performance on the table.
Q: Does the Aqara G400 need a subscription?
A: No — and this is the biggest reason it kills Ring. The Aqara G400 offers free local recording to a microSD card (up to 512GB) and free cloud recording through Apple HomeKit Secure Video (stored in your iCloud). Ring charges $4.99/month for basic video history, which adds up to $60/year indefinitely.
Q: How does the Aqara G400 compare to the Ring Doorbell?
A: The Aqara G400 delivers 2K resolution versus Ring's 1080p on comparably priced models, includes local storage at no extra cost, and requires zero subscriptions. Ring offers a larger ecosystem and broader smart home compatibility, but you're locked into a monthly fee to access your own recordings. For privacy-conscious users who don't want cloud dependency, the G400 wins decisively.
Q: Can the Aqara G400 record locally?
A: Yes, the G400 supports local recording to a microSD card up to 512GB, which gives you roughly 30+ days of continuous recording depending on resolution settings. This means your footage stays in your home, not on a corporate server. You can also back up clips to iCloud via HomeKit Secure Video at no additional cost if you have an iCloud+ plan.
Q: Does the Aqara G400 work with Alexa?
A: The Aqara G400 does not natively support Alexa or Amazon Echo Show for live video streaming. It's designed primarily for the Apple HomeKit and Aqara Home ecosystems. If Alexa compatibility is a dealbreaker, you'll need to look at Ring or Reolink — but you'll be trading away the G400's subscription-free model and local storage advantages.
Q: Is the Aqara G400 wired or wireless?
A: The Aqara G400 is a wired doorbell camera that uses your existing doorbell wiring (8-24V AC). This means no battery charging, no downtime, and consistent power for features like 24/7 continuous recording. If you don't have existing doorbell wiring, you'll need a plug-in transformer or an electrician to install one.
