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 it makes Ring's entire business model look like a shakedown. 2K resolution, HomeKit Secure Video with free encrypted cloud storage, on-device AI, and zero monthly fees. Ever.

Why Another Doorbell Camera?
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.
The Aqara Doorbell Camera G400 launched 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.
What You Get for $100
Aqara didn't cut corners to hit this price point — they cut the subscription.
- 2K resolution (2304 × 1296) — sharper than most budget doorbells and some cameras twice its price
- 165° field of view with a 3:4 aspect ratio — portrait-style view captures faces AND packages on the ground
- Dual-band Wi-Fi 6 (802.11ax) — better interference handling, stable connections at range
- PoE or traditional 16-24V AC wiring — drop-in replacement for existing wired doorbells
- On-device AI — person, package, vehicle, and animal detection processed locally. No cloud dependency.
- Two-way audio with noise cancellation, infrared night vision, IP65 weather resistance
Compare that to the Ring Video Doorbell 4 at $149.99. You're paying 50% more for slightly less resolution, no local processing without a subscription, and the privilege of funding Ring's surveillance partnership program.
HomeKit Secure Video — The Privacy Advantage
This is 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.
What HKSV gives you:
- End-to-end encryption — video encrypted on the camera before it leaves your network. Apple can't see it. Aqara can't see it. Nobody can except your iCloud-signed devices.
- Free iCloud storage — recordings don't count against your storage quota (requires iCloud+ plan, starting at $0.99/month)
- On-device facial recognition — with Apple TV or HomePod as home hub, "Someone is at the door" becomes "Mom is at the door"
- Activity zones — reduce noise from busy streets
- 10-day clip history — automatic motion-triggered storage
Ring's approach: stores your video on Amazon's servers, has shared footage with over 2,000 law enforcement agencies (sometimes without warrants), and encrypts data in transit but not end-to-end by default — meaning Amazon holds the keys.
HKSV gives you genuinely private, encrypted, free cloud storage. Ring charges you $100/year for the privilege of storing footage on servers cops can access.
Installation and Setup
Big caveat: the G400 is wired only. No battery option. You need:
- Existing doorbell wiring (16-24V AC transformer), or
- Power over Ethernet (PoE)
For homeowners with existing wired doorbells: ~20-minute swap. Remove old doorbell, connect two wires, mount the G400, scan QR code in Aqara Home app, add to Apple Home.
For renters: this is a dealbreaker. No battery backup, no solar option, no workaround.
The PoE option is particularly interesting for new builds or renovations — one Ethernet cable handles both power and data.
What It Does Well
The 3:4 Aspect Ratio Is a Game-Changer
Traditional 16:9 cameras give you a wide view of your porch — great for sunsets, useless for seeing packages at your feet. The 3:4 ratio captures the full vertical span from visitor's head to ground. This should be the standard.
On-Device AI = Fewer False Alerts
Person/package/vehicle/animal detection runs locally. No cloud round-trip, no subscription required:
- Faster notifications (no server processing delay)
- Works even if internet goes down (clips save to microSD)
- Dramatically fewer false positives from shadows, rain, and wind
Wi-Fi 6 Actually Matters for Doorbells
Your front door is probably the farthest point from your router. Wi-Fi 6 with dual-band means faster live view loads and more reliable clip recording.
The Price
- Year 1 with Ring Doorbell 4 + Ring Protect Basic: $199.98
- Year 1 with Aqara G400: $99.99
By year three, you've saved nearly $250. That's a second camera.
What It Doesn't Do
- No Matter support — HomeKit and Aqara ecosystem only. No Google Home or SmartThings through Matter.
- No battery option — wired-only locks out renters
- Apple ecosystem required for best features (HKSV). Android users can use Aqara Home app with local storage, but lose the killer feature.
- No Thread radio — Wi-Fi only. Fine for video streaming, but no mesh networking.
3-Year Cost Comparison
| Feature | Aqara G400 | Ring Doorbell 4 | Google Nest (Wired) |
|---|---|---|---|
| Price | $99.99 | $149.99 | $179.99 |
| Resolution | 2K | 1536p | 1080p |
| Subscription/yr | $0 | $39.99-$99.99 | $0-$79.99 |
| Local Storage | microSD | No | No |
| Free Cloud | Yes (HKSV) | No | 3 hours |
| E2E Encryption | Yes | Opt-in (disables features) | No |
| On-Device AI | Yes (free) | No (subscription) | Limited free |
| 3-Year Total | $99.99 | $269-$450 | $180-$420 |
The Ring Doorbell 4 can cost you up to $450 over three years. The Aqara G400 costs $99.99. Period. Forever.
The Bottom Line
The Aqara G400 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. Ring chooses not to, because subscriptions are more profitable than respecting customers.
For $100, you get a doorbell camera that outspecs Ring's $150 offering, stores footage for free, encrypts everything, and will never ask you for another dollar.
Score: 8.5/10
✅ Pros: Unbeatable price, 2K resolution, HKSV encryption, on-device AI, Wi-Fi 6, local storage, total privacy
❌ Cons: Wired only, Apple ecosystem required for best features, no Matter, no Thread
BUY IT if you're an Apple HomeKit household with doorbell wiring.
DON'T BUY IT if you're a renter without wiring, Android-only, or deep in Alexa/Google Home.
