Let’s get started!

What’s in the Box?

Before you begin, make sure you have all the components that come with your Eufy E340 doorbell. Here’s what should be included:

• Eufy E340 Video Doorbell (main unit)
• Rechargeable battery (pre-installed)
• Mounting plate
• Screws and wall anchors
• Angled mounting wedge (for adjusting camera angle)
• Chime connector (for wired installations)
• USB-C charging cable
• Quick start guide

Take a moment to inspect each item. If anything is missing or damaged, contact Eufy customer support before proceeding.

Choosing Your Installation Method: Wired vs. Wireless

The Eufy E340 gives you flexibility—you can install it using existing doorbell wiring or go completely wire-free with the built-in rechargeable battery. Here’s how to decide:

Wired Installation

Best if you already have a working doorbell circuit (typically 8–24V AC). This method provides continuous power, so you never have to worry about charging the battery. It also enables the doorbell to ring your existing mechanical or digital chime.

Wireless Installation

Ideal for renters, homes without doorbell wiring, or if you prefer a cleaner look without exposed wires. The battery lasts up to 6 months on a single charge (depending on usage), and you can recharge it via USB-C. Note: Wireless mode does not support ringing your existing chime—you’ll rely on the Eufy app notifications or a separate Eufy Chime (sold separately).

Pro Tip: Even if you go wireless, consider wiring it if possible—it’s more reliable and eliminates battery maintenance.

Tools You’ll Need

Gather these tools before starting:

• Phillips-head screwdriver
• Drill (with 3/16” drill bit)
• Level (to ensure the doorbell is straight)
• Pencil (for marking drill holes)
• Voltage tester (for wired installations—safety first!)
• Smartphone or tablet with the Eufy Security app installed
• Ladder (if your doorbell is high up)

Having everything ready will save time and prevent frustration mid-installation.

Step 1: Turn Off Power (For Wired Installations)

If you’re replacing an existing wired doorbell, safety is critical. Follow these steps:

Locate Your Circuit Breaker

Find the breaker that controls your doorbell. It’s often labeled “Doorbell,” “Chime,” or “Front Door.” If unsure, turn off the main breaker to be safe.

Test the Wires

Use a non-contact voltage tester to confirm the power is off. Touch the tester to the doorbell wires—if it beeps or lights up, the power is still on. Double-check your breaker and test again.

Remove the Old Doorbell

Unscrew the old doorbell from the wall. Gently pull it away to expose the two wires. Do not cut them—leave them intact for the new installation.

Safety Reminder: Never work on live wires. If you’re unsure about electrical work, consult a licensed electrician.

Step 2: Download and Set Up the Eufy Security App

The Eufy Security app is essential for configuring your doorbell, viewing live footage, and receiving alerts. Here’s how to get started:

Download the App

Search for “Eufy Security” in the App Store (iOS) or Google Play Store (Android). Install it on your smartphone or tablet.

Create an Account

Open the app and tap “Sign Up” to create a new account. Use a valid email and strong password. Verify your email if prompted.

Add Your Device

Tap the “+” icon in the app and select “Video Doorbell.” Choose “E340” from the list. The app will guide you through the setup process, including connecting to Wi-Fi and scanning the QR code on the doorbell.

Tip: Make sure your phone is connected to the same Wi-Fi network you want the doorbell to use (2.4 GHz only—the E340 doesn’t support 5 GHz).

Step 3: Prepare the Mounting Location

Now it’s time to position your doorbell. Follow these steps for the best results:

Choose the Right Height

Mount the doorbell at about 48 inches (4 feet) from the ground. This height captures most visitors’ faces clearly and reduces tampering risk.

Check Wi-Fi Signal Strength

Use your phone to check the Wi-Fi signal at the installation spot. Weak signal = poor performance. If needed, install a Wi-Fi extender or consider a wired setup for better reliability.

Decide on Mounting Angle

The E340 comes with a flat mounting plate and an optional angled wedge. Use the wedge if you need to tilt the camera downward (e.g., if mounting above a porch step). Test the angle by holding the doorbell in place and checking the preview in the app.

Mark the Drill Holes

Hold the mounting plate against the wall at your chosen location. Use a level to ensure it’s straight. Mark the screw holes with a pencil.

Step 4: Install the Mounting Plate

With your holes marked, it’s time to secure the mounting plate:

Drill Pilot Holes

Use a 3/16” drill bit to create pilot holes at the marked spots. This prevents the wall from cracking, especially on brick or concrete.

Insert Wall Anchors (If Needed)

If you’re mounting into drywall, plaster, or masonry, insert the included wall anchors into the holes. Tap them gently with a hammer until flush.

Attach the Mounting Plate

Align the plate with the holes and secure it using the provided screws. Make sure it’s tight and level.

Pro Tip: For brick or stucco, use a masonry drill bit and plastic anchors for a secure hold.

Step 5: Connect the Wires (Wired Installation Only)

If you’re using existing wiring, follow these steps:

Strip the Wire Ends

Use wire strippers to expose about 1/4 inch of copper on each wire. Twist the ends to prevent fraying.

Attach the Chime Connector

The Eufy E340 includes a small chime connector. Insert the two doorbell wires into the connector’s terminals (polarity doesn’t matter). Tighten the screws to secure.

Connect to the Doorbell

Plug the chime connector into the port on the back of the Eufy E340. It will click into place.

Note: The chime connector allows the doorbell to ring your existing chime. Without it, the doorbell will only send app notifications.

Step 6: Attach the Doorbell to the Mounting Plate

Now for the fun part—mounting the doorbell:

Align and Secure

Hold the Eufy E340 against the mounting plate. Slide it downward until it clicks into place. You’ll hear a satisfying snap when it’s secure.

Test the Fit

Gently tug on the doorbell to ensure it’s locked in. It should not wobble or come loose.

Adjust the Angle (If Using the Wedge)

If you’re using the angled wedge, attach it between the mounting plate and the doorbell before securing. This tilts the camera for better coverage.

Step 7: Power On and Test the Doorbell

Time to bring your doorbell to life:

Turn Power Back On (Wired Only)

If you turned off the breaker, switch it back on. The doorbell should power up automatically.

Check the App

Open the Eufy Security app. You should see a live video feed from your doorbell. If not, check your Wi-Fi connection and ensure the doorbell is properly connected.

Test Motion Detection

Walk in front of the doorbell to trigger motion detection. You should receive a notification on your phone. Adjust sensitivity in the app if needed.

Test the Chime (Wired Only)

Press the doorbell button. Your existing chime should ring. If not, double-check the chime connector and wiring.

Check Night Vision and Audio

Test the doorbell at night to ensure color night vision works. Also, speak through the app to test two-way audio.

Step 8: Customize Settings in the App

Once installed, personalize your doorbell for the best experience:

Set Motion Zones

In the app, go to Device Settings > Motion Detection. Draw zones to focus on areas like your walkway and ignore busy streets.

Adjust Notification Preferences

Choose when to receive alerts (e.g., only during certain hours). You can also enable “Do Not Disturb” mode.

Enable Human Detection

Turn on AI-powered person detection to reduce false alerts from pets or moving shadows.

Set Up Recording Options

The E340 stores footage locally on a microSD card (sold separately) or in the cloud (with a subscription). Choose your preference in the app.

Invite Family Members

Share access with family by inviting them via email in the app. They’ll get their own login and notifications.

Troubleshooting Common Issues

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

Doorbell Won’t Power On

• Wired: Check breaker, wiring, and chime connector. Use a voltage tester to confirm power.
• Wireless: Charge the battery fully using the USB-C cable. It may take 4–6 hours.

Poor Wi-Fi Connection

• Ensure the doorbell is within 100 feet of the router (less through walls).
• Restart your router and the doorbell.

No Chime Sound (Wired)

• Verify the chime connector is properly installed.
• Check that your existing chime is compatible (most are).
• Test with a multimeter to ensure voltage is reaching the chime.

Blurry or Dark Video

• Clean the camera lens with a soft, dry cloth.
• Adjust the mounting angle to avoid glare from sunlight or porch lights.
