What You’ll Need Before You Begin

Before touching any wires, make sure you have the right tools and materials. Rushing into installation without preparation can lead to frustration, damage, or even safety hazards.

Here’s a checklist of what you’ll need:

• Eufy Doorbell Wired unit – Make sure it’s the wired version (not the battery model).
• Screwdriver set – Both Phillips and flathead may be needed.
• Voltage tester (non-contact) – To confirm power is off.
• Wire strippers – For trimming and exposing wire ends if needed.
• Drill and drill bits – For mounting the plate if your wall requires it.
• Level – To keep the doorbell straight.
• Pencil – For marking drill points.
• Smartphone with Eufy Security app installed – Available on iOS and Android.
• Wi-Fi network (2.4 GHz only) – The Eufy Doorbell Wired does not support 5 GHz networks.

Pro Tip: If your existing doorbell wires are too short or damaged, you may need a few inches of 18–22 gauge doorbell wire to extend them. Most hardware stores carry this.

Step 1: Check Compatibility and Power Requirements

Not all doorbell systems are created equal. The Eufy Doorbell Wired requires a specific voltage range to function properly. Installing it on an incompatible system can lead to poor performance, frequent disconnections, or even damage.

Check Your Transformer Voltage

Your doorbell runs on a small transformer that steps down your home’s 120V power to a safer, lower voltage. The Eufy Doorbell Wired needs:

• 8–24V AC (Alternating Current)
• At least 10VA (Volt-Amps)

Most modern doorbells use 16V or 24V transformers, which are compatible. Older homes might have 6V or 8V transformers—these may work, but 10VA or higher is ideal for consistent performance.

How to check:

1. Turn off power at the circuit breaker.
2. Remove your existing doorbell from the wall.
3. Look at the wires—trace them back to the chime inside your home.
4. Locate the transformer (usually near the chime, furnace, or electrical panel).
5. Check the label for voltage (V) and VA rating.

If your transformer is below 8V or under 10VA, consider upgrading it. A 16V 30VA transformer is a popular, affordable replacement that works great with Eufy.

Note: The Eufy Doorbell Wired does not require a mechanical chime. It works with digital chimes or can be used without any indoor chime at all (you’ll get notifications on your phone instead).

Step 2: Turn Off the Power

Safety first! Even though doorbell voltage is low, it’s still electricity—and mistakes can damage your doorbell or cause injury.

Locate the Correct Circuit Breaker

Doorbell circuits are often labeled “Doorbell,” “Chime,” or “Front Door.” If unsure:

1. Turn off breakers one by one.
2. Test your existing doorbell button—when it no longer rings, you’ve found the right one.
3. Label it for future reference.

Double-Check with a Voltage Tester

Even after turning off the breaker, use a non-contact voltage tester near the doorbell wires to confirm no power is present. Touch the tester to each wire—if it beeps or lights up, power is still on. Go back and double-check the breaker.

Never skip this step. It only takes a second and could save your device—or your safety.

Step 3: Remove Your Old Doorbell

Now that power is off, it’s time to remove the old doorbell.

Unscrew and Disconnect

1. Use a screwdriver to remove the mounting screws.
2. Gently pull the doorbell away from the wall.
3. You’ll see two wires connected to the back—usually labeled “Front” and “Trans” or just two terminals.

Important: Don’t let the wires fall back into the wall! Use a piece of tape to hold them out or have a helper assist.

Label the Wires (Optional but Helpful)

If your wires aren’t color-coded, label them with tape (e.g., “Left” and “Right”) so you know which goes where. The Eufy doorbell is not polarity-sensitive, but keeping track helps avoid confusion.

Inspect the Wires

Check for fraying, corrosion, or damage. If the wires are brittle or too short, strip back a small section (about 1/4 inch) to expose fresh copper. Use wire strippers for a clean cut.

Pro Tip: If the wires are too short to reach the new mounting plate, use a wire nut and a short piece of spare doorbell wire to extend them.

Step 4: Install the Eufy Mounting Plate

The Eufy Doorbell Wired comes with a sturdy mounting plate that attaches to your wall. This plate holds the doorbell securely and hides the wiring.

Position the Plate

1. Hold the mounting plate against the wall where you want the doorbell.
2. Use a level to ensure it’s straight.
3. Mark the screw holes with a pencil.

Ideal Height: Mount the doorbell 48–52 inches from the ground. This ensures clear facial recognition and prevents tampering.

Drill Pilot Holes (If Needed)

If you’re mounting into wood or need extra support:

1. Use a drill bit slightly smaller than your screws.
2. Drill pilot holes at the marked spots.
3. This prevents cracking and makes screwing easier.

For Brick or Concrete: Use a masonry bit and wall anchors. Drill carefully and clean out dust before inserting anchors.

Secure the Plate

1. Align the plate with the holes.
2. Insert screws and tighten with a screwdriver or drill (don’t over-tighten).
3. Ensure the plate is flush and secure—no wobbling.

Step 5: Connect the Wires to the Eufy Doorbell

Now it’s time to wire up your new doorbell. The Eufy Doorbell Wired has two terminals: “Front” and “Trans.” These correspond to your existing doorbell wires.

Prepare the Wires

1. Strip about 1/4 inch of insulation from each wire end if not already done.
2. Twist the exposed copper to prevent fraying.

Attach the Wires

1. Loosen the terminal screws on the back of the Eufy doorbell.
2. Insert one wire into the “Front” terminal and the other into “Trans.”
3. Tighten the screws securely—don’t overtighten, but ensure no loose strands.

Note: The Eufy doorbell is not polarity-sensitive, so it doesn’t matter which wire goes where. However, consistency helps if you ever need to troubleshoot.

Double-Check Connections

Give each wire a gentle tug to ensure it’s secure. Loose connections can cause power issues or intermittent operation.

Step 6: Attach the Doorbell to the Mounting Plate

With the wires connected, it’s time to snap the doorbell onto the plate.

Align and Secure

1. Hold the doorbell so the pins on the back align with the slots on the mounting plate.
2. Slide it downward until it clicks into place.
3. You should hear a satisfying snap—this means it’s locked in.

Pro Tip: If it doesn’t click, double-check that the wires aren’t pinched or blocking the connection. Gently push from the sides if needed.

Test the Fit

Give the doorbell a light tug to ensure it’s secure. It should not move or wobble.

Step 7: Turn the Power Back On

Now that everything is connected, restore power.

1. Go back to your circuit breaker.
2. Turn the doorbell circuit back on.
3. Wait 10–15 seconds for the doorbell to power up.

You should see the LED light on the front of the Eufy doorbell blink or glow. This indicates it’s receiving power and initializing.

What to Expect:
– The LED may flash blue, white, or red during startup.
– It may take up to a minute to fully boot up.

If the light doesn’t turn on, don’t panic—we’ll cover troubleshooting later.

Step 8: Set Up the Eufy Security App

The Eufy app is your control center for the doorbell. It handles Wi-Fi setup, notifications, motion zones, and more.

Download and Open the App

1. Install the Eufy Security app from the App Store (iOS) or Google Play (Android).
2. Create an account or log in if you already have one.

Add Your Doorbell

1. Tap the “+” icon in the app.
2. Select “Video Doorbell” > “Wired.”
3. Follow the on-screen instructions.

The app will guide you through:

• Scanning the QR code on the back of the doorbell (or entering the serial number manually).
• Connecting to your 2.4 GHz Wi-Fi network (5 GHz is not supported).
• Entering your Wi-Fi password.
• Waiting for the doorbell to connect (this may take 1–2 minutes).

Pro Tip: Stand close to your router during setup for the strongest signal. Weak Wi-Fi can cause connection failures.

Customize Settings

Once connected, you can:

• Set up motion detection zones (e.g., ignore trees, focus on the walkway).
• Adjust sensitivity to reduce false alerts.
• Enable or disable two-way audio.
• Choose notification preferences (push, email, etc.).
• Enable human-only detection to filter out animals and vehicles.

Step 9: Test Your Doorbell

Before calling it a day, test everything to ensure it works properly.

Test the Video and Audio

1. Open the Eufy app and view the live feed.
2. Check for clear video, good lighting, and no distortion.
3. Tap the microphone icon and speak—test two-way audio.

Test Motion Detection

Walk in front of the doorbell. You should receive a notification on your phone within a few seconds.

Test the Doorbell Button

Press the button on the front. You should hear a chime (if connected to a digital chime) and receive a push notification.

Note: If you’re not using a chime, you’ll only get phone alerts—this is normal.

Troubleshooting Common Issues

Even with careful installation, problems can arise. Here are solutions to the most common issues.

Doorbell Won’t Power On
