This flexibility, combined with military-grade encryption and user-centric privacy controls, makes it a top contender for anyone serious about protecting their home and personal data. In this comprehensive guide, we’ll explore how the Aqara G4 smart video doorbell stores your home security footage safely, ensuring your privacy isn’t compromised in the name of convenience.

Understanding the Storage Options of the Aqara G4 Smart Video Doorbell

The Aqara G4 stands out in the crowded smart doorbell market by offering a multi-layered storage approach that prioritizes both accessibility and security. Instead of locking users into a single storage model, Aqara provides three primary options: local microSD storage, encrypted local network storage via the Aqara Hub, and optional cloud storage through Aqara Cloud Services. This tiered system ensures that users can choose the level of convenience, cost, and privacy that best fits their lifestyle.

1. Local Storage via microSD Card (Up to 512GB)

The most privacy-focused option is local storage using a microSD card. The Aqara G4 supports cards up to 512GB, allowing for weeks or even months of continuous 2K video recordings, depending on motion activity. This method stores all footage directly on the device, meaning no data ever leaves your home network. This is ideal for users concerned about third-party access, data breaches, or government surveillance.

• No subscription required: Once you purchase the microSD card, there are no recurring fees.
• Full control over data: You own the footage and can access it anytime via the Aqara app or by removing the card.
• Encrypted at rest: The G4 uses AES-128 encryption to protect data stored on the card, preventing unauthorized access even if the card is physically stolen.

Tip: For optimal performance, use a high-endurance microSD card (like SanDisk High Endurance or Samsung PRO Endurance), as these are designed for constant video writing and are less likely to fail under heavy use.

2. Local Network Storage via Aqara Hub (M1S, M2, or E1)

For users who want centralized control without relying on the cloud, the Aqara Hub offers a powerful alternative. When paired with the G4, the hub can automatically back up motion-triggered clips and live streams over your local Wi-Fi network. These backups are stored on the hub’s internal memory or connected storage (like a USB drive), all encrypted using end-to-end AES encryption.

• Centralized security ecosystem: The hub acts as a local server, managing not just doorbell footage but also data from other Aqara sensors (motion, door, window, etc.).
• No internet required for playback: If your internet goes down, you can still access stored clips via the app on your local network.
• Automated retention policies: You can set the hub to keep footage for 7, 14, or 30 days, after which older clips are automatically overwritten.

Example: A homeowner in a rural area with unreliable internet can use the hub to maintain 24/7 local backups, ensuring they never miss a delivery or suspicious activity, even during outages.

3. Cloud Storage via Aqara Cloud Services (Optional Subscription)

For those who want offsite redundancy and remote access from anywhere, Aqara offers a cloud storage plan. The service is GDPR-compliant and stores data in secure, geographically distributed data centers. Clips are encrypted both in transit (TLS 1.3) and at rest (AES-256), meeting enterprise-grade security standards.

• 7-day or 30-day rolling storage: Choose a plan based on your retention needs.

• Instant push notifications with video previews: When motion is detected, you get a clip within seconds, even if you’re not on your home network.
• Family sharing: Multiple users can access the cloud feed, ideal for households with elderly parents or frequent visitors.

Tip: If you’re concerned about privacy, you can use cloud storage for alerts and previews while keeping full-resolution clips on your microSD card—a hybrid approach that balances convenience and control.

How Aqara G4 Ensures Data Security and Privacy

In an age of data breaches and smart home vulnerabilities, the Aqara G4 smart video doorbell takes privacy seriously. From hardware design to software protocols, every aspect of the G4 is engineered to protect your footage from unauthorized access. Let’s break down the key security features that make the G4 one of the safest smart doorbells on the market.

End-to-End Encryption (E2EE) for Local and Cloud Transmissions

The G4 uses end-to-end encryption for all video streams and stored footage. Whether data is moving from the doorbell to your phone, from the hub to the cloud, or between Aqara servers, it’s encrypted using AES-128 or AES-256 standards. This means even if someone intercepts the data, they can’t view it without your encryption key.

• Live video streams are encrypted in real-time using TLS 1.3.
• Stored clips on the hub or cloud are encrypted at rest with unique device keys.
• No backdoor access: Aqara does not store decryption keys, ensuring only you can access your footage.

Secure Authentication and Access Controls

The Aqara app employs two-factor authentication (2FA) and biometric login (fingerprint or face recognition) to prevent unauthorized access. Additionally, you can set up user roles—for example, allowing your teenager to view the doorbell feed but not delete recordings or change settings.

Example: A parent can grant temporary access to a house cleaner via a time-limited guest account, ensuring the cleaner can monitor deliveries but can’t access historical footage.

GDPR and CCPA Compliance

Aqara is headquartered in China but operates under strict data protection regulations, including GDPR (Europe) and CCPA (California). This means:

• You can request a full data export or deletion at any time.
• Cloud data is stored in your region (e.g., EU data stays in EU data centers).
• No data is sold to third parties for advertising.

Local-Only Mode (No Cloud Dependency)

For maximum privacy, the G4 supports a “local-only” mode. In this mode:

• No data is uploaded to the cloud, even if you have a subscription.
• All processing (motion detection, facial recognition) happens on-device or on the hub.
• Remote access is still possible via secure peer-to-peer (P2P) connections, but only when you’re connected to your home network or using a trusted mobile device.

Tip: Enable local-only mode if you’re concerned about government surveillance or live in a country with strict data laws.
