Let’s get started!

What’s in the Box?

Before you begin, make sure you have all the components. Here’s what comes with your Eufy S340 camera:

• Eufy S340 camera unit
• Weatherproof power cable (16.4 feet / 5 meters)
• Power adapter (12V/1.5A)
• Mounting bracket and screws
• Wall anchors
• Quick start guide
• Screwdriver (small, for bracket adjustment)

Double-check these items before starting. If anything is missing, contact Eufy support right away.

Step 1: Choose the Best Location

Picking the right spot is crucial for performance and security. Here’s what to consider:

Wi-Fi Signal Strength

The S340 connects to your home Wi-Fi, so it needs a strong signal. Use your phone to check signal strength at the installation spot. If it’s weak, consider a Wi-Fi extender or mesh system.

Field of View

Aim for a location that covers key areas like entry points, driveways, or yards. Avoid pointing the camera directly at bright lights or the sun, which can cause glare.

Power Access

The S340 isn’t truly wire-free—it needs constant power via the included cable. Plan a route from your power source (outlet or junction box) to the camera. Use outdoor-rated extension cords or conduit if running wires along walls or underground.

Height and Angle

Mount the camera 8–10 feet high for optimal coverage. Tilt it slightly downward to capture faces and movement clearly. Avoid mounting too high, which can distort images.

Weather Protection

While the S340 is weather-resistant (IP65 rated), avoid placing it where it’s directly exposed to heavy rain or snow. Under an eave or porch is ideal.

Step 2: Prepare the Mounting Surface

Once you’ve picked your spot, prepare the wall or surface for mounting.

Check for Obstructions

Make sure there are no pipes, wires, or studs behind the wall where you’ll drill. Use a stud finder if needed.

Mark the Mounting Holes

Hold the mounting bracket against the wall at your desired height. Use a pencil to mark the screw holes. Ensure the bracket is level using a spirit level.

Drill Pilot Holes

Drill small pilot holes at the marked spots. This makes it easier to insert screws and prevents wall damage. Use wall anchors if mounting on brick, concrete, or drywall without studs.

Step 3: Run the Power Cable

The S340 requires constant power, so running the cable properly is essential.

Route the Cable Safely

Run the weatherproof power cable from the camera location to your power source. Avoid sharp edges or pinch points that could damage the cable.

Use Conduit for Underground Runs

If running the cable underground, use PVC conduit to protect it from moisture and pests. Bury the conduit at least 6 inches deep.

Secure the Cable

Use cable clips or zip ties to secure the cable along walls, fences, or trim. Keep it tidy and out of the way to prevent tripping hazards.

Connect to Power

Plug the power adapter into an outdoor-rated GFCI outlet. If no outdoor outlet is available, use a weatherproof extension cord rated for outdoor use.

Step 4: Mount the Camera

Now it’s time to attach the camera to the wall.

Attach the Bracket

Secure the mounting bracket to the wall using the provided screws and anchors. Make sure it’s tight and level.

Connect the Power Cable

Plug the weatherproof cable into the camera’s port. The connector is keyed, so it only fits one way. Push it in firmly until it clicks.

Mount the Camera

Slide the camera onto the bracket until it locks into place. Use the small screwdriver to tighten the locking screw on the side of the bracket. This prevents theft and ensures stability.

Adjust the Angle

Tilt and swivel the camera to your desired angle. Test the view using the Eufy app (see next step) before finalizing.

Step 5: Download and Set Up the Eufy App

The Eufy Security app is essential for setup and control.

Download the App

Install the “Eufy Security” app from the Apple App Store or Google Play Store. It’s free and works on iOS and Android.

Create an Account

Open the app and sign up with your email. Verify your account via the confirmation email.

Add Your Camera

Tap the “+” icon in the app and select “Add Device.” Choose “S340” from the list.

Scan the QR Code

Point your phone at the QR code on the camera or the quick start guide. The app will detect the camera automatically.

Connect to Wi-Fi

Enter your Wi-Fi network name (SSID) and password. The app will send this info to the camera. Make sure your phone is connected to the same 2.4GHz network (the S340 doesn’t support 5GHz).

Wait for Pairing

The camera will connect to your network. This may take 1–2 minutes. You’ll see a confirmation message when it’s ready.

Step 6: Configure Camera Settings

Once connected, customize your camera for the best experience.

Name Your Camera

Give it a descriptive name like “Front Door” or “Backyard” for easy identification.

Set Up Motion Detection

Go to “Detection Settings” and adjust sensitivity. Choose between “Human Only,” “All Motion,” or “Pet” to reduce false alerts.

Enable Two-Way Audio

Turn on two-way talk so you can speak through the camera. Test it by tapping the microphone icon in the app.

Adjust Video Quality

Set video resolution to 2K for the best clarity. You can lower it to 1080p if you have bandwidth concerns.

Schedule Recording

Use “Smart Detection” to record only when motion is detected. Or set a schedule for continuous recording during specific hours.

Enable Night Vision

The S340 has color night vision. Make sure it’s enabled in the settings. It uses built-in spotlights to illuminate the area at night.

Step 7: Test the Camera

Before finishing, test everything to ensure it works.

Check Live View

Open the app and view the live feed. Make sure the image is clear and the angle covers the desired area.

Test Motion Alerts

Walk in front of the camera to trigger motion detection. You should receive a push notification on your phone.

Verify Night Vision

Turn off the lights and check the night vision feed. The camera should switch to color mode with the spotlight on.

Test Two-Way Audio

Speak into your phone and listen through the camera. Also, talk near the camera and hear yourself through the app.

Check Power and Connection

Ensure the camera stays online and doesn’t disconnect. If it does, check Wi-Fi strength and power supply.

Step 8: Secure and Maintain Your Camera

Keep your camera in top shape with regular care.

Tighten All Screws

After a few days, check that all mounting screws are tight. Vibration from wind or movement can loosen them over time.

Clean the Lens

Wipe the lens with a soft, dry cloth every few weeks to remove dust, dirt, or water spots. Avoid harsh chemicals.

Inspect the Power Cable

Check the cable for wear, cuts, or animal damage. Replace it if needed.

Update Firmware

The Eufy app will notify you of firmware updates. Install them to improve performance and security.

Review Recordings

Check your event history regularly to ensure motion detection is working and alerts are accurate.

Troubleshooting Common Issues

Even with careful installation, problems can happen. Here’s how to fix the most common ones.

Camera Won’t Connect to Wi-Fi

• Make sure you’re using a 2.4GHz network (not 5GHz).
• Move closer to the router during setup.
• Restart your router and camera.
• Reset the camera by holding the sync button for 10 seconds.

Blurry or Dark Video

• Clean the lens with a microfiber cloth.
• Adjust the camera angle to avoid glare.
• Ensure night vision is enabled and the spotlight isn’t blocked.

Frequent Disconnections

• Check Wi-Fi signal strength at the camera location.
• Reduce interference from other devices.
• Use a Wi-Fi extender if needed.

No Motion Alerts

• Verify motion detection is enabled in the app.
• Increase sensitivity or switch to “All Motion.”
• Ensure the camera isn’t pointed at moving trees or shadows.

Power Issues

• Check that the power adapter is plugged in securely.
• Test the outlet with another device.
• Inspect the cable for damage.
