What's in the Box
Inside the box you'll find the doorbell unit (with built-in chime), USB-C charging cable, removal tool, mounting adhesives, screws, installation guide, and a 32GB microSD card (in some markets). Build quality is plastic but sturdy, with a minimalist white design.
Installation
Installation is surprisingly easy. The G4 directly replaces your existing door peephole — no wiring, drilling, or professional needed. Unscrew the old peephole, attach the mounting bracket, snap the doorbell on, and you're done. The whole process takes 5-10 minutes.
Pairing with the Aqara Home app uses Bluetooth initially, then connects to your WiFi. If you use HomeKit, the doorbell appears automatically. Important note: it requires 2.4GHz WiFi — 5GHz is not supported.
Video and Audio Quality
The camera is 1080p with a 162° field of view and a 1:1 (square) aspect ratio. Daytime image quality is very good — clear faces, vivid colors, fast focus. At night, the infrared Night Vision provides decent footage up to 5 meters away.
Audio is two-way — you can talk and listen to visitors through your phone. Audio quality is good with minimal lag (~1 second latency). The built-in chime rings loudly enough to hear throughout an entire apartment.
Motion Detection and Face Recognition
The G4 supports on-device face recognition — no cloud required. You can register family members' faces and receive personalized notifications ("Mom is at the door"). Motion detection uses a PIR sensor with adjustable sensitivity (low, medium, high).
In practice, face recognition works reliably in 85-90% of cases. In poor lighting or unusual angles, it may fail. Motion detection is accurate — rare false alerts on medium sensitivity. You can set detection zones to avoid triggers from passing traffic or pets.
Zigbee Hub Functionality
Here's the big surprise. The G4 functions as a full Zigbee 3.0 hub — you can connect up to 128 Aqara devices (door sensors, temperature sensors, motion sensors, switches, and more). No separate Aqara Hub needed if you don't already have one.
This means for €80-100, you get a doorbell + camera + Zigbee hub in one device. Perfect for those starting an Aqara ecosystem without additional purchases. It supports automations through Aqara Home or HomeKit Scenes.
Example Automation
When the doorbell detects motion → hallway lights turn on + you receive a phone notification + video recording starts on the microSD card. All processed locally, no cloud dependency.
Storage and Cloud
One of the biggest advantages: local storage on microSD card (up to 512GB). No cloud subscription required — videos are stored locally on the device. You can view recordings through the app or HomeKit Secure Video.
For cloud backup, HomeKit Secure Video is supported (via iCloud+ — 50GB plan at €0.99/month). Videos are encrypted end-to-end. Aqara Cloud is also available as an alternative, but local storage is sufficient for most users who want a subscription-free experience.
Aqara Home App
The Aqara Home app (iOS and Android) is well-designed. You can view live feed, browse older recordings, adjust motion sensitivity, manage face profiles, and create automations. Response is quick — live view opens in 2-3 seconds. Notifications are prompt and customizable.
Battery Life
The built-in 6700mAh battery lasts 4-6 months with normal use (10-20 events daily). Enabling continuous recording drastically reduces battery life. Charging is via USB-C — remove the device, charge for 2-3 hours, and reinstall. A minor inconvenience, but the long battery life makes it manageable.
