How to Add SD Card to Eufy Doorbell: A Complete Step-by-Step Guide

If you’ve recently installed a Eufy doorbell or are looking to upgrade your current setup, you might be wondering how to add an SD card for local video storage. Unlike many smart doorbells that rely on cloud subscriptions, Eufy offers a unique advantage: local recording via a microSD card. This means you can store footage directly on the device—no monthly fees, no privacy concerns, and full control over your data.

In this comprehensive guide, we’ll walk you through everything you need to know about adding an SD card to your Eufy doorbell. Whether you’re using a Eufy Video Doorbell Dual, Solo, or any other model that supports local storage, these steps will help you set up, format, and manage your microSD card with ease. We’ll also cover tips for choosing the right card, troubleshooting common problems, and maximizing your doorbell’s recording capabilities.

By the end of this guide, you’ll be able to confidently install an SD card, configure local recording, and enjoy uninterrupted, secure video storage—all without relying on the cloud.

Why Add an SD Card to Your Eufy Doorbell?

Before diving into the installation process, it’s important to understand why adding an SD card is beneficial. Eufy doorbells are designed with privacy and cost-efficiency in mind. While they offer optional cloud storage, many users prefer local recording for several reasons:

• No subscription fees: Cloud plans often require monthly or annual payments. With local storage, you pay once for the SD card and never again.
• Enhanced privacy: Your video footage stays on your property, reducing the risk of data breaches or third-party access.
• Faster access to recordings: Local files load quicker than cloud-based videos, especially during network congestion.
• Reliable during internet outages: Even if your Wi-Fi goes down, the doorbell continues recording to the SD card.
• Longer retention periods: Depending on card size and recording settings, you can store weeks or even months of footage locally.

Not all Eufy doorbell models support SD cards, so it’s essential to check your device’s specifications. Models like the Eufy Video Doorbell Dual, Video Doorbell Solo (Wired and Battery), and Video Doorbell S330 typically include a microSD card slot. Always refer to your user manual or Eufy’s official website to confirm compatibility.

What You’ll Need Before Starting

To successfully add an SD card to your Eufy doorbell, gather the following items:

• A compatible microSD card (more on this below)
• A microSD card adapter (if your computer doesn’t have a built-in slot)
• The Eufy Security app installed on your smartphone (iOS or Android)
• Access to your doorbell (mounted and powered)
• A small flathead screwdriver or paperclip (for some models)

Make sure your doorbell is fully charged (if battery-powered) or properly wired and receiving power. Also, ensure your smartphone is connected to the same Wi-Fi network as your doorbell during setup.

Choosing the Right SD Card for Your Eufy Doorbell

Not all microSD cards are created equal—especially when it comes to security devices like doorbells. Using an incompatible or low-quality card can lead to recording failures, corrupted files, or even damage to your device. Here’s what to look for:

Recommended Specifications

• Capacity: 8GB to 128GB. Eufy officially supports up to 128GB, but smaller cards (16GB–32GB) are often sufficient for most users.
• Speed Class: Class 10 or UHS-I (U1). These ensure smooth video writing and prevent lag or dropped frames.
• File System: FAT32. Most microSD cards come pre-formatted as FAT32, but larger cards (64GB and above) may use exFAT, which Eufy doesn’t support. You’ll need to reformat them.
• Brand Reliability: Stick with trusted brands like SanDisk, Samsung, Kingston, or Lexar. Avoid no-name or counterfeit cards.

Why FAT32 Matters

Eufy doorbells require the SD card to be formatted in FAT32. This older file system has a 4GB file size limit, but it’s widely compatible and stable for continuous recording. Cards larger than 32GB often come formatted as exFAT, which Eufy cannot read. If you’re using a 64GB or 128GB card, you’ll need to format it to FAT32 before inserting it into the doorbell.

How to Format a Large SD Card to FAT32

If your card is 64GB or larger, follow these steps to format it correctly:

1. Insert the microSD card into your computer using an adapter.
2. Open “This PC” (Windows) or “Finder” (Mac).
3. Right-click the SD card and select “Format.”
4. Choose “FAT32” as the file system.
5. Uncheck “Quick Format” for a thorough erase (recommended).
6. Click “Start” and wait for the process to complete.

Note: On Windows, the built-in formatter may not allow FAT32 for cards over 32GB. In that case, use a free tool like Rufus or GUIFormat to force FAT32 formatting.

Step-by-Step: How to Add SD Card to Eufy Doorbell

Now that you have the right card and it’s properly formatted, it’s time to install it. The process varies slightly depending on your Eufy doorbell model, but the general steps remain the same.

Step 1: Power Off the Doorbell

Safety first! Before inserting or removing the SD card, you must power off your doorbell. This prevents data corruption and protects the card and device.

• For wired models: Turn off the power at the circuit breaker or disconnect the wires from the doorbell terminal.
• For battery-powered models: Remove the battery from the back of the doorbell. Some models have a small latch or screw to release the battery cover.

Wait about 10–15 seconds after powering off to ensure the device is fully shut down.

Step 2: Locate the SD Card Slot

The microSD card slot is typically located on the back or side of the doorbell. On most Eufy models, it’s a small, spring-loaded tray or a direct slot.

• Eufy Video Doorbell Dual: The slot is on the back, near the bottom. You may need to gently pry open a small cover.
• Eufy Video Doorbell Solo: The slot is on the side, accessible without removing the doorbell from the mount.
• Eufy Video Doorbell S330: The slot is behind the battery compartment. Remove the battery to access it.

If you’re unsure, consult your user manual or check Eufy’s support page for your specific model.

Step 3: Insert the microSD Card

Once you’ve located the slot, follow these steps:

1. Hold the microSD card with the gold contacts facing down and the label side facing up.
2. Gently slide the card into the slot until it’s fully seated. You should feel a slight click or resistance.
3. Do not force the card. If it doesn’t go in easily, double-check the orientation.
4. For models with a tray: Push the tray in until it clicks. For direct slots, the card should sit flush with the surface.

Avoid touching the gold contacts with your fingers, as oils and dirt can interfere with connectivity.

Step 4: Power On the Doorbell

After inserting the card, restore power to your doorbell:

• Wired models: Reconnect the wires or turn the circuit breaker back on.
• Battery models: Reinsert the battery and ensure it’s securely in place.

Wait for the doorbell to boot up. The LED indicator should light up (usually white or blue), signaling that it’s online.

Step 5: Open the Eufy Security App

Launch the Eufy Security app on your smartphone. Make sure you’re logged into your account and that your doorbell is connected to the app.

• Tap on your doorbell device from the home screen.
• Go to “Device Settings” (usually represented by a gear icon).
• Look for “Storage” or “Local Storage” in the menu.

Step 6: Format the SD Card via the App

Even if you pre-formatted the card on your computer, Eufy recommends formatting it again through the app for optimal performance.

1. In the “Storage” section, you should see your SD card listed.
2. Tap “Format SD Card.”
3. Confirm the action when prompted. This will erase all data on the card.
4. Wait for the formatting process to complete (usually takes 1–3 minutes).

Once formatted, the app will display the available storage space and confirm that the card is ready for use.

Step 7: Enable Local Recording

With the SD card installed and formatted, it’s time to turn on local recording.

1. In the app, go to “Device Settings” > “Recording Settings.”
2. Toggle on “Local Recording” or “SD Card Recording.”
3. Choose your preferred recording mode:
   • Event Recording: Saves clips only when motion or a doorbell press is detected.
   • Continuous Recording: Records 24/7 (uses more storage but ensures no gaps).
4. Set motion detection zones and sensitivity if desired.

You can also adjust clip length (e.g., 15, 30, or 60 seconds) and enable pre-recording to capture a few seconds before motion is detected.

Tips for Managing Your SD Card and Recordings

Now that your SD card is active, here are some best practices to keep everything running smoothly:

Monitor Storage Space

Check your available storage regularly through the Eufy app. When the card nears full capacity, older clips are automatically overwritten (if enabled). However, you can also manually delete old recordings:

• Go to “Playback” or “Event History” in the app.
• Select and delete individual clips or clear all recordings.

Replace the Card When Needed

microSD cards have a limited lifespan—typically 3–5 years with regular use. Signs it’s time to replace the card include:

• Frequent recording failures
• Corrupted or missing video files
• Slow performance or lag
• Error messages in the app

Always keep a spare card on hand for quick swaps.

Protect the Card from Extreme Conditions

While Eufy doorbells are weather-resistant, extreme heat, cold, or moisture can affect SD card performance. Avoid exposing the doorbell to direct sunlight for long periods or installing it in areas prone to flooding.

Backup Important Footage

Since local storage is not backed up automatically, consider downloading important clips to your phone or computer. In the Eufy app, tap the download icon next to any recording to save it locally.

Troubleshooting Common SD Card Issues

Even with proper setup, you might encounter problems. Here’s how to fix the most common issues:

“SD Card Not Detected” Error

If your doorbell doesn’t recognize the card:

• Power off the doorbell and reinsert the card, ensuring it’s fully seated.
• Try a different microSD card to rule out hardware failure.
• Reformat the card to FAT32 using your computer or the Eufy app.
• Check for physical damage to the card or slot.

Recording Stops or Skips Frames

This usually indicates a slow or faulty card:

• Replace the card with a Class 10 or UHS-I model.
• Avoid using cards labeled “High Endurance” unless specifically recommended—they’re often overkill and may not be optimized for Eufy.
• Ensure the card isn’t nearly full; low space can cause performance issues.

Corrupted Files or Playback Errors

If videos won’t play or appear glitchy:

• Reformat the SD card through the app.
• Delete corrupted clips manually.
• Update your Eufy app and doorbell firmware to the latest version.

Doorbell Won’t Power On After Inserting Card

This is rare but can happen if the card is inserted incorrectly:

• Remove the SD card and power on the doorbell to confirm it works without the card.
• Reinsert the card carefully, ensuring proper orientation.
• If the problem persists, contact Eufy support—there may be a hardware issue.
