Let’s get started!

What You’ll Need Before You Begin

Before diving into the setup, make sure you have the following items ready:

• Eufy S340 camera – Fully charged or connected to a power source.
• Smartphone or tablet – iOS 11.0 or later, or Android 6.0 or later.
• Eufy Security app – Downloaded and installed on your device.
• Wi-Fi network – Must be 2.4 GHz (the S340 doesn’t support 5 GHz).
• Wi-Fi password – Have it handy; you’ll need to enter it during setup.
• Stable internet connection – For app downloads and camera configuration.
• QR code sticker – Usually found on the camera or in the box.

Having these ready will save you time and frustration. Let’s move on to the first step.

Step 1: Download and Install the Eufy Security App

The Eufy Security app is your control center for all Eufy devices, including the S340. It’s where you’ll set up the camera, view live feeds, adjust settings, and receive notifications.

How to Download the App

Open your device’s app store:

• On iPhone: Open the App Store and search for “Eufy Security.”
• On Android: Open Google Play Store and search for “Eufy Security.”

Tap “Install” or “Get” and wait for the download to complete. Once installed, open the app.

Create or Log In to Your Eufy Account

If you’re new to Eufy:

• Tap “Sign Up” and enter your email address.
• Create a strong password (at least 8 characters, with a mix of letters, numbers, and symbols).
• Verify your email by clicking the link sent to your inbox.

If you already have an account:

• Tap “Log In” and enter your credentials.

Once logged in, you’ll see the home screen with options to add a new device.

Step 2: Power On Your Eufy S340 Camera

Now it’s time to wake up your camera.

Charge or Connect the Camera

The Eufy S340 can be powered in two ways:

• Battery-powered: Charge the camera fully using the included USB-C cable and adapter. A full charge takes about 4–6 hours and lasts up to 180 days, depending on usage.
• Wired power: Use the included weatherproof power adapter and cable for continuous power. Ideal for high-traffic areas where the camera is constantly active.

For initial setup, we recommend using wired power to avoid any interruptions.

Turn On the Camera

Once powered:

• Press and hold the power button (located on the side of the camera) for 3 seconds.
• You’ll hear a voice prompt: “Welcome to Eufy Security.”
• The LED light on the front will blink blue, indicating the camera is in setup mode.

If the light doesn’t blink blue, the camera may already be connected or in a different mode. Try resetting it (we’ll cover that later).

Step 3: Add the Camera in the Eufy Security App

Now that your camera is on and ready, let’s add it to the app.

Open the App and Tap “Add Device”

From the home screen:

• Tap the “+” icon in the top-right corner.
• Select “Security Camera” from the list.
• Choose “EufyCam S340” when prompted.

The app will now search for nearby devices. Make sure your phone is connected to the same Wi-Fi network you plan to use for the camera.

Scan the QR Code

This is a crucial step. The app will ask you to scan the QR code on your camera.

• Hold your phone about 6–12 inches from the camera’s lens.
• Position the QR code (usually on a sticker on the back or bottom) within the camera frame on your phone.
• The app will automatically detect and scan the code.

If the scan fails:

• Make sure the camera is powered on and in setup mode (blue blinking light).
• Clean the camera lens and QR code sticker.
• Try scanning in a well-lit area.
• Manually enter the serial number if prompted (found on the QR code label).

Once scanned, the app will connect to the camera and begin the Wi-Fi setup process.

Step 4: Connect Eufy S340 to Wi-Fi

This is the heart of the process—getting your camera online.

Select Your Wi-Fi Network

The app will display a list of available Wi-Fi networks. Look for your home network (SSID).

• Tap on your 2.4 GHz Wi-Fi network.
• Do not select a 5 GHz network—the S340 doesn’t support it.
• If you have a dual-band router (2.4 GHz and 5 GHz), make sure the 2.4 GHz network has a distinct name (e.g., “HomeWiFi_2.4”).

If you don’t see your network:

• Move closer to your router.
• Ensure the router is broadcasting the 2.4 GHz signal.
• Restart your router if needed.

Enter Your Wi-Fi Password

Carefully type in your Wi-Fi password. The app will show dots or asterisks, so double-check for typos.

• Use the “Show Password” toggle to verify accuracy.
• Avoid special characters if possible—some users report issues with symbols like @, #, or spaces.
• If your password is complex, consider temporarily changing it to a simpler one (e.g., “password123”) just for setup, then change it back later.

Once entered, tap “Next” or “Connect.”

Wait for the Connection

The app will now send the Wi-Fi credentials to the camera. This can take 30 seconds to 2 minutes.

• The camera’s LED will blink blue rapidly during this process.
• Once connected, the light will turn solid blue, and you’ll hear a voice prompt: “Wi-Fi connected.”
• The app will confirm: “Camera added successfully.”

If the connection fails:

• Check that you entered the correct password.
• Ensure the camera is within 30–50 feet of the router.
• Try moving the camera closer temporarily during setup.
• Restart the camera and router.

Step 5: Configure Camera Settings

Now that your Eufy S340 is online, it’s time to customize it to your needs.

Name Your Camera

Give your camera a descriptive name, like “Front Door” or “Backyard.” This makes it easier to identify if you have multiple cameras.

Set Up Motion Detection Zones

The S340 uses AI to distinguish between people, vehicles, and animals. You can define specific areas to monitor.

• Tap “Motion Detection” in the app.
• Draw zones on the live video feed where you want alerts (e.g., driveway, walkway).
• Avoid areas with moving trees or shadows to reduce false alarms.

Adjust Sensitivity and Alerts

• Set motion sensitivity to “High,” “Medium,” or “Low” based on your environment.
• Enable push notifications so you get alerts on your phone.
• Choose whether to receive alerts for people, vehicles, or all motion.

Enable Night Vision and Audio

• Night vision is automatic, but you can adjust brightness in the app.
• Enable two-way audio to speak through the camera (great for greeting visitors or scaring off intruders).

Set Up Recording Preferences

The S340 supports local storage via a microSD card (sold separately) or cloud storage (subscription required).

• For local recording: Insert a microSD card (up to 128GB, Class 10 or higher) into the camera.
• For cloud recording: Subscribe to Eufy Cloud (optional, but recommended for backup).
• Choose continuous or event-based recording.

Step 6: Test Your Camera

Before calling it a day, make sure everything works.

Check Live View

• Open the app and tap on your camera.
• You should see a live video feed within 5–10 seconds.
• If the image is blurry, clean the lens with a microfiber cloth.

Test Motion Detection

• Walk in front of the camera.
• You should receive a notification within 10–15 seconds.
• Check the recorded clip in the app’s “Events” tab.

Test Two-Way Audio

• Tap the microphone icon in the live view.
• Speak clearly—your voice should play through the camera’s speaker.
• Ask someone near the camera to confirm they can hear you.

Verify Night Vision

• Turn off the lights or wait for nighttime.
• The camera should switch to black-and-white night vision automatically.
• Check the live feed for clear visibility.

If any feature isn’t working, don’t panic—we’ll cover troubleshooting next.
