How to Factory Reset Eufy Solocam S40

This guide walks you through how to factory reset your Eufy SoloCam S40 safely and effectively. Whether you’re troubleshooting issues or preparing to sell your camera, these clear steps ensure a complete reset without data loss surprises.

Key Takeaways

• Factory reset erases all settings: This includes Wi-Fi credentials, motion zones, and custom schedules, returning the camera to its original state.
• Use the physical reset button: The S40 has a dedicated reset button on the device—no app required for the initial reset.
• Ensure full battery before resetting: A low battery can interrupt the process and cause errors or incomplete resets.
• Reconnect via the Eufy app after reset: You’ll need to set up the camera again as if it were new, including pairing and Wi-Fi configuration.
• Reset resolves many common issues: Problems like connection drops, unresponsiveness, or sync errors are often fixed with a factory reset.
• Keep the camera powered during reset: Do not unplug or turn off the camera while the reset is in progress to avoid corruption.
• Reset doesn’t delete cloud recordings: If you have a Eufy Security subscription, your stored videos remain safe in the cloud.

How to Factory Reset Eufy SoloCam S40: A Complete Step-by-Step Guide

So, you’ve got a Eufy SoloCam S40—maybe it’s acting up, or perhaps you’re planning to sell it or give it to a friend. Whatever the reason, knowing how to factory reset your Eufy SoloCam S40 is a must-have skill. A factory reset wipes all your personalized settings and returns the camera to its original out-of-the-box state. It’s like giving your camera a fresh start.

In this guide, we’ll walk you through the entire process—from preparation to post-reset setup—so you can reset your SoloCam S40 with confidence. We’ll also cover troubleshooting tips, common mistakes to avoid, and what to expect after the reset. Whether you’re a tech newbie or a seasoned smart home user, this guide is designed to be simple, clear, and helpful.

Why Would You Need to Factory Reset Your Eufy SoloCam S40?

Before diving into the steps, let’s talk about why you might want to reset your camera. There are several common scenarios where a factory reset is the best solution:

• Camera is unresponsive: If your SoloCam S40 freezes, won’t turn on, or doesn’t respond to app commands, a reset can often fix the issue.
• Wi-Fi connection problems: If your camera keeps dropping offline or won’t reconnect to your network, resetting it can clear corrupted network settings.
• Preparing to sell or gift the camera: A factory reset ensures your personal data—like motion zones and schedules—is completely removed.
• Switching to a new Wi-Fi network: While you can change Wi-Fi settings in the app, a full reset guarantees a clean slate for setup.
• After a failed firmware update: If an update caused glitches, resetting the camera can restore stability.

Now that you know when a reset is useful, let’s get into the actual process.

What You’ll Need Before Starting

Before you begin, make sure you have the following ready:

• A fully charged SoloCam S40: The reset process takes a few minutes, and you don’t want the battery dying mid-reset. If your camera is solar-powered, ensure it’s had enough sun exposure or use the included USB-C cable to charge it.
• Access to the camera’s physical reset button: This is located on the bottom of the device. You’ll need a paperclip, SIM tool, or small pin to press it.
• The Eufy Security app installed on your phone: You’ll need this to reconfigure the camera after the reset.
• Your Wi-Fi network name (SSID) and password: After the reset, you’ll need to reconnect the camera to your network.
• A stable Wi-Fi connection: Make sure your home network is working properly to avoid setup issues later.

Once you’ve checked off these items, you’re ready to begin.

Step 1: Locate the Reset Button on Your SoloCam S40

The Eufy SoloCam S40 doesn’t have a touchscreen or menu system like some other cameras. Instead, it uses a physical reset button for factory resets. Here’s how to find it:

Find the Reset Button

Flip your SoloCam S40 upside down. On the bottom edge, you’ll see a small, recessed button labeled “Reset.” It’s usually next to the USB-C charging port. The button is tiny and flush with the casing, so you’ll need a thin tool to press it.

Use the Right Tool

Grab a paperclip, SIM ejector tool, or any small, straight pin. Straighten the paperclip if needed. You’ll need to insert it into the small hole and press firmly.

Ensure the Camera is Powered On

Before pressing the button, make sure the camera is powered. If it’s completely dead, charge it for at least 30 minutes using the USB-C cable. A reset won’t work if the camera has no power.

Once you’ve located the button and confirmed the camera is on, move to the next step.

Step 2: Perform the Factory Reset

Now it’s time to actually reset the camera. This process is quick but requires precision.

Press and Hold the Reset Button

Insert your paperclip or tool into the reset hole and press the button firmly. You don’t need to jam it in—just enough to feel it click.

Hold for 10 Seconds

Keep the button pressed for at least 10 seconds. You’ll notice the camera’s LED light start to blink. This is normal and indicates the reset is in progress.

Watch for LED Indicators

After about 10 seconds, release the button. The LED light will change patterns:

• Solid blue: The camera is rebooting.
• Blinking blue: The camera is in pairing mode, ready to be set up again.

If the light turns solid green, the camera is powered on but not yet connected. Wait a minute or two for it to enter pairing mode.

Wait for the Reset to Complete

The entire reset process takes about 1–2 minutes. Do not unplug the camera or press any buttons during this time. Interrupting the reset can cause software corruption or leave the camera in a non-functional state.

Once the LED is blinking blue, the factory reset is complete. Your SoloCam S40 is now back to its original settings.

Step 3: Reconnect Your SoloCam S40 to the Eufy App

Now that the camera has been reset, it’s time to set it up again—just like the first time you unboxed it.

Open the Eufy Security App

Launch the Eufy Security app on your smartphone. Make sure you’re logged into your account. If you don’t have an account, create one—it’s free and required for camera setup.

Tap “Add Device”

On the home screen, tap the “+” icon or “Add Device” button. The app will scan for nearby Eufy devices.

Select “SoloCam S40”

When your camera appears in the list, tap on it. The app will guide you through the setup process.

Follow the On-Screen Instructions

The app will ask you to:

• Confirm the camera’s LED is blinking blue.
• Connect to the camera’s temporary Wi-Fi network (it will appear as “eufy_security_XXXX”).
• Enter your home Wi-Fi network name and password.
• Wait while the camera connects to your network.

This process usually takes 1–3 minutes. Once connected, the camera will appear in your app with a new device name (you can rename it later).

Step 4: Reconfigure Your Camera Settings

After the reset, all your previous settings are gone. Here’s what you’ll need to set up again:

Set Motion Detection Zones

Go to the camera’s settings in the app and tap “Motion Detection.” Draw zones where you want the camera to monitor activity. Avoid areas like busy streets or tree branches that cause false alerts.

Adjust Sensitivity Levels

Choose between low, medium, or high sensitivity. High sensitivity catches more motion but may trigger false alarms. Start with medium and adjust based on performance.

Enable or Disable Recording Modes

Decide whether you want continuous recording, event-based recording, or scheduled recording. Most users prefer event-based to save storage and battery.

Set Up Alerts

Choose how you want to receive notifications: push alerts, email, or both. You can also set quiet hours to avoid disturbances at night.

Check Night Vision and Audio Settings

Test the infrared night vision and two-way audio to ensure they’re working properly. Adjust the microphone and speaker volume if needed.

Take your time with these settings—they’ll determine how well your camera performs in real-world use.

Troubleshooting Common Reset Issues

Even with careful steps, things can sometimes go wrong. Here are some common problems and how to fix them:

Camera Won’t Enter Pairing Mode After Reset

If the LED stays solid green or red instead of blinking blue, the reset may not have completed properly. Try the reset process again, ensuring you hold the button for a full 10 seconds. Make sure the battery is above 50%.

App Can’t Find the Camera

If the Eufy app doesn’t detect your SoloCam S40, try the following:

• Restart your phone and the app.
• Move closer to the camera (within 10 feet).
• Ensure your phone is connected to the same Wi-Fi network you plan to use.
• Reset the camera again and wait longer for it to enter pairing mode.

Wi-Fi Connection Fails During Setup

If the camera can’t connect to your Wi-Fi:

• Double-check your network name and password.
• Ensure your Wi-Fi is 2.4 GHz (the S40 doesn’t support 5 GHz).
• Move the camera closer to your router during setup.
• Restart your router and try again.

Camera Keeps Going Offline

If your camera disconnects frequently after reset:

• Check for Wi-Fi interference (microwaves, cordless phones).
• Ensure the camera is within range of your router.
• Update the Eufy app and camera firmware.
• Consider using a Wi-Fi extender if the signal is weak.

LED Light Doesn’t Respond

If pressing the reset button does nothing:

• Confirm the camera has power (charge it fully).
• Try a different tool to press the button.
• Contact Eufy support—the button or internal hardware may be faulty.

Most issues can be resolved with patience and retries. If problems persist, Eufy’s customer support is generally responsive and helpful.

Tips for a Smooth Factory Reset Experience

To make the reset process as hassle-free as possible, keep these tips in mind:

• Charge the camera fully before starting: A low battery is the #1 cause of reset failures.
• Perform the reset in a quiet, well-lit area: This helps you see the LED and avoid mistakes.
• Use a stable Wi-Fi network: Avoid public or guest networks during setup.
• Don’t rush the process: Wait for each step to complete before moving on.
• Keep your phone close to the camera: Bluetooth and Wi-Fi signals are stronger when devices are near each other.
• Write down your Wi-Fi password: You’ll need it during setup, and it’s easy to forget.
• Update the Eufy app regularly: New versions often include bug fixes and improved setup flows.

Following these best practices will save you time and frustration.

What Happens to Your Data After a Reset?

A common concern is whether a factory reset deletes your recordings. Here’s the breakdown:

• Local recordings (on SD card): If you use a microSD card, the reset does not erase the card. However, the camera will no longer recognize the card until you reformat it in the app. Your videos remain safe but inaccessible until reformatted.
• Cloud recordings: If you have a Eufy Security subscription, your cloud-stored videos are tied to your account, not the camera. They remain safe and accessible even after a reset.
• App settings and preferences: All custom settings—like motion zones, schedules, and alerts—are erased. You’ll need to recreate them.
• Device name and location: The camera will revert to its default name (e.g., “SoloCam S40”) and lose any assigned location in the app.

In short: your cloud data is safe, but local settings are wiped. Always back up important footage before resetting.

When to Contact Eufy Support

Most reset issues can be solved with the steps above. But if you’ve tried everything and your camera still won’t reset or connect, it’s time to reach out for help.

Contact Eufy support if:

• The reset button doesn’t respond even with a charged battery.
• The camera won’t power on at all.
• The app consistently fails to detect the camera after multiple resets.
• You suspect hardware damage (e.g., water exposure, drop damage).

Eufy offers support via email, live chat, and phone. Have your camera’s serial number ready (found on the bottom or in the app) to speed up the process.

Final Thoughts: Reset with Confidence

Factory resetting your Eufy SoloCam S40 might seem intimidating at first, but it’s actually a straightforward process once you know the steps. Whether you’re fixing a glitch, preparing to sell, or just starting fresh, a reset gives your camera a clean slate.

Remember: always charge your camera, use the physical reset button, and follow the app’s setup guide carefully. With a little patience, you’ll have your SoloCam S40 up and running like new in just a few minutes.

And don’t forget—your cloud recordings are safe, so you won’t lose any important footage. Just be ready to reconfigure your settings and enjoy the improved performance that often comes after a reset.

Now go ahead—press that reset button with confidence. Your Eufy SoloCam S40 will thank you.
