How to Expand Eufy Homebase 3 Storage

If you’re using the Eufy Homebase 3 as the brain of your home security system, you already know how powerful and reliable it is. It supports multiple cameras, offers local storage, and keeps your data private—no monthly fees, no cloud dependency. But what happens when your built-in storage starts to fill up? That’s where expanding your Eufy Homebase 3 storage comes in.

In this guide, we’ll walk you through the entire process of adding external storage to your Homebase 3. Whether you’re a tech newbie or a seasoned DIYer, you’ll learn how to connect a hard drive, format it properly, and manage your recordings like a pro. By the end, you’ll have more space for video footage, longer retention times, and peace of mind knowing your home is always monitored.

Let’s get started.

Why Expand Your Eufy Homebase 3 Storage?

Before we dive into the steps, let’s talk about why expanding storage is such a smart move.

The Eufy Homebase 3 comes with built-in storage—usually 16GB or 32GB, depending on the model. While that’s enough for basic use, it fills up fast, especially if you have multiple cameras recording motion events or using continuous recording. Once the storage is full, the system starts overwriting the oldest clips. That means you could lose important footage just when you need it.

By adding an external drive, you can:

– Store weeks or even months of video footage
– Keep high-resolution recordings without compression
– Avoid constant manual deletions
– Improve system performance by reducing write cycles on internal storage

Plus, since everything stays local, your data remains private and secure. No uploading to third-party servers. No risk of breaches. Just you, your cameras, and your expanded storage.

What You’ll Need

Before you begin, make sure you have the following:

• Eufy Homebase 3 unit: Make sure it’s powered on and connected to your Wi-Fi network.
• External USB drive: A hard disk drive (HDD) or solid-state drive (SSD) with USB 3.0 or higher. We recommend at least 1TB for meaningful expansion.
• USB cable: Most external drives come with one, but ensure it’s USB-A to USB-B or USB-A to USB-C, depending on your drive.
• Eufy Security app: Installed on your smartphone or tablet (iOS or Android).
• Stable internet connection: Needed for app communication with the Homebase 3.

Pro tip: Avoid using flash drives (like USB sticks). They’re not designed for constant read/write cycles and may fail quickly under surveillance workloads.

Step 1: Choose the Right External Drive

Not all external drives are created equal—especially when it comes to security systems.

The Eufy Homebase 3 supports external storage, but only certain types work reliably. Here’s what to look for:

Drive Type: HDD vs. SSD

• HDD (Hard Disk Drive): Affordable and available in large capacities (up to 8TB or more). Great for long-term storage. However, they have moving parts, so they’re more prone to failure if bumped or dropped.
• SSD (Solid-State Drive): Faster, quieter, and more durable. No moving parts mean better reliability for continuous recording. Slightly more expensive, but worth it for peace of mind.

For most users, a 2TB or 4TB external HDD is a sweet spot between cost and capacity. If you want top performance and longevity, go with an SSD.

USB Compatibility

The Homebase 3 has a USB 3.0 port, so your drive should support USB 3.0 or higher. USB 2.0 drives may work, but they’ll be slower and could cause buffering or recording gaps.

Also, make sure the drive is externally powered or draws enough power from the USB port. Some large HDDs need their own power adapter—check the manufacturer’s specs.

File System Requirements

The Eufy Homebase 3 supports drives formatted in exFAT or NTFS. Avoid FAT32, as it has a 4GB file size limit—too small for long video clips.

If your drive is brand new, it might come pre-formatted as exFAT (common for Windows) or HFS+ (Mac). That’s fine—you can reformat it during setup.

Step 2: Connect the External Drive to Homebase 3

Now that you’ve got the right drive, it’s time to plug it in.

Locate the USB Port

On the back of your Eufy Homebase 3, you’ll find a single USB 3.0 port. It’s usually labeled and colored blue to indicate USB 3.0 compatibility.

Plug in the Drive

1. Connect the USB cable from your external drive to the Homebase 3’s USB port.
2. If your drive has a separate power adapter, plug it into a wall outlet.
3. Turn on the drive (if it has a power switch).

Wait a few seconds. The Homebase 3 should detect the drive automatically. You might see a small LED light up on the drive or hear it spin up (if it’s an HDD).

Check Initial Connection

Open the Eufy Security app on your phone. Go to Devices, select your Homebase 3, and look for a notification or storage status update. If the app says “External storage detected,” you’re on the right track.

If nothing happens, try:
– Reconnecting the USB cable
– Using a different USB port on the drive (if available)
– Testing the drive on a computer to ensure it’s working

Step 3: Format the Drive in the Eufy App

Even if your drive is already formatted, the Eufy app may ask you to reformat it for optimal performance. This ensures compatibility and prepares the drive for surveillance use.

Open the Eufy Security App

1. Launch the app and log in to your account.
2. Tap on Devices at the bottom.
3. Select your Homebase 3 from the list.

Navigate to Storage Settings

1. Tap on the Settings icon (usually a gear or three dots).
2. Look for Storage or Storage Management.
3. You should see your internal storage and the newly connected external drive listed.

Format the External Drive

1. Tap on the external drive.
2. Select Format or Initialize.
3. Confirm the action when prompted.

⚠️ Warning: Formatting will erase all data on the drive. Make sure you’ve backed up anything important before proceeding.

The formatting process may take a few minutes, depending on the drive size. Once complete, the app will show the new storage capacity and confirm it’s ready for use.

Step 4: Configure Recording Settings

Now that your external drive is connected and formatted, it’s time to set up how your cameras use the new storage.

Choose Recording Mode

The Eufy Homebase 3 supports two main recording modes:

• Event-Based Recording: Records only when motion is detected. Saves space but may miss brief events.
• Continuous Recording: Records 24/7. Uses more storage but ensures nothing is missed.

With expanded storage, you can afford to use continuous recording without worrying about running out of space too quickly.

To change the mode:

1. In the Eufy app, go to Devices.
2. Select one of your cameras.
3. Tap Recording Settings.
4. Choose Continuous or Event-Based.

Repeat for each camera.

Set Video Quality and Retention

Higher video quality (like 2K or 4K) looks better but uses more storage. You can balance quality and space by adjusting settings:

1. In the camera settings, tap Video Quality.
2. Choose between High, Medium, or Low.
3. For most users, Medium offers a good compromise.

You can also set how long footage is kept before being overwritten:

1. Go to Storage Management in the Homebase 3 settings.
2. Look for Retention Period or Auto-Delete.
3. Choose a duration (e.g., 30, 60, or 90 days).

The longer the retention, the more storage you’ll need. With a 4TB drive, you could store 90 days of continuous 1080p footage from two cameras.

Step 5: Monitor and Maintain Your Storage

Expanding storage isn’t a “set it and forget it” task. Regular maintenance ensures your system stays reliable.

Check Drive Health

The Eufy app shows the status of your external drive:

1. Go to Devices > Homebase 3 > Storage.
2. Look for indicators like “Healthy,” “Warning,” or “Error.”

If you see a warning, it could mean:
– The drive is almost full
– The connection is unstable
– The drive is failing

Manage Storage Usage

Over time, your drive will fill up. Here’s how to stay on top of it:

• Review footage regularly: Delete unimportant clips manually to free up space.
• Use smart alerts: Set up motion zones to reduce false recordings (like trees swaying).
• Upgrade when needed: If you’re constantly running low, consider a larger drive.

Backup Important Footage

Even with expanded storage, local drives can fail. Always back up critical clips:

1. In the Eufy app, go to Events or Playback.
2. Select a video clip.
3. Tap the download or share icon to save it to your phone or cloud storage.

You can also enable Cloud Backup (if available) for an extra layer of protection—though this may require a subscription.

Troubleshooting Common Issues

Even with careful setup, you might run into problems. Here’s how to fix the most common ones.

Drive Not Detected

If the Homebase 3 doesn’t recognize your drive:

• Try a different USB cable or port.
• Test the drive on a computer to confirm it’s working.
• Ensure the drive is formatted to exFAT or NTFS.
• Restart the Homebase 3 by unplugging it for 10 seconds.

Slow Performance or Buffering

This could be due to:

• A USB 2.0 drive—upgrade to USB 3.0 or higher.
• A nearly full drive—free up space or add a larger one.
• Too many cameras recording at high resolution—lower video quality or reduce frame rate.

Drive Disconnects Frequently

Possible causes:

• Loose USB connection—reseat the cable.
• Insufficient power—use a powered USB hub or drive with its own adapter.
• Faulty drive—replace it if problems persist.

Formatting Fails

If the app won’t format the drive:

• Format it manually on a computer first (use exFAT).
• Ensure the drive isn’t write-protected (check for a physical switch).
• Try a different drive—some brands aren’t fully compatible.

Tips for Long-Term Success

To get the most out of your expanded storage, follow these best practices:

• Use a high-quality drive: Invest in a reputable brand like Western Digital, Seagate, or Samsung.
• Keep firmware updated: Check for Homebase 3 firmware updates in the app.
• Avoid physical shocks: Mount the drive securely to prevent damage.
• Label your drive: Write “Eufy Backup” on it so no one accidentally unplugs it.
• Check monthly: Spend 5 minutes each month reviewing storage status and footage.
