Pro Tip: If your existing doorbell has very short wires, consider using wire extenders or a junction box to make connections easier.

Step 1: Check Compatibility and Power Requirements

Not all homes are ready for a smart doorbell. The eufy doorbell wired needs a compatible electrical setup to work properly. Skipping this step could lead to malfunction or damage.

Check Your Existing Doorbell System

Most homes with a traditional doorbell have a low-voltage system powered by a transformer. Here’s how to verify yours is compatible:

Locate your doorbell transformer: It’s usually near your doorbell chime inside the house, often in a basement, closet, or attic. It looks like a small metal box with wires coming out.
Check the voltage: Use a multimeter to test the voltage across the doorbell wires at the chime or at the doorbell location. The eufy doorbell wired requires 16–24 volts AC. If it’s below 16V, the doorbell may not power on. If it’s above 24V, it could damage the device.
Confirm wire gauge: Standard 18–22 AWG wires are ideal. Thinner wires may not carry enough current.

Example: If your transformer says “16V 10VA” on the label, that’s perfect. If it says “8V,” you’ll need to upgrade the transformer before installing the eufy doorbell.

What If Your System Isn’t Compatible?

Don’t worry—there are solutions:

Upgrade the transformer: Buy a 16V or 24V doorbell transformer (around $15–$25) and have an electrician install it if you’re not comfortable doing it yourself.
Use a plug-in transformer: Some models allow you to bypass the existing system and power the doorbell via an outlet near the door. Check eufy’s compatibility guide for details.

Important: Never install a wired doorbell on a system with line voltage (120V AC). That’s extremely dangerous and will destroy the device.

Step 2: Turn Off the Power

Safety first! Even though doorbell systems use low voltage, it’s still electricity—and mistakes can cause shocks, short circuits, or damage to your home’s wiring.

How to Safely Shut Off Power

Find your home’s main electrical panel (breaker box).
Locate the breaker labeled “doorbell,” “chime,” or “front door.” If there isn’t one, look for breakers that control outlets or lights near the doorbell.
Switch the breaker to OFF.
Test the power: Go to your existing doorbell and press the button. If the chime doesn’t sound, power is off. For extra safety, use a non-contact voltage tester on the wires at the doorbell location.

Pro Tip: Place a piece of tape over the breaker switch with “DO NOT TURN ON – WORK IN PROGRESS” written on it. This prevents someone from accidentally restoring power while you’re working.

Step 3: Remove the Old Doorbell

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

Step-by-Step Removal

Unscrew the old doorbell plate: Use a screwdriver to remove the screws holding the doorbell to the wall.
Gently pull the doorbell away from the wall: This will expose the two wires connected to the back.
Take a photo of the wiring: Snap a clear picture of how the wires are connected. This helps if you need to reconnect the old doorbell later.
Loosen the terminal screws: On most doorbells, there are two screws—one for the “front” wire and one for the “transformer” wire. Loosen them and carefully remove the wires.
Cap the wires: Use wire nuts or electrical tape to cover the exposed ends. This prevents them from touching each other or the wall.

Note: If your old doorbell was mounted with adhesive or had a single wire, you may need to patch small holes or use filler before installing the new bracket.

Step 4: Install the Eufy Mounting Bracket

The mounting bracket is the backbone of your installation. It holds the doorbell securely and ensures the camera is angled correctly.

Choose the Right Bracket Angle

Eufy includes multiple bracket options to fit different wall angles:

Standard bracket: For flat walls (0° angle).
15° or 30° angled bracket: For walls that slope inward or outward. Use these if your doorbell is mounted on a corner or angled surface.

Choose the bracket that gives the best view of your doorstep. You want to see visitors from head to toe and capture packages left on the ground.

Mount the Bracket Securely

Hold the bracket against the wall: Position it where the old doorbell was, or choose a new spot if preferred.
Use a level to ensure it’s straight: A crooked doorbell looks unprofessional and can affect video quality.
Mark the screw holes with a pencil.
Drill pilot holes (if needed): Especially important for brick, stucco, or concrete walls. Use a masonry bit for tough surfaces.
Secure the bracket with screws: Use the provided screws and a screwdriver. Make sure it’s tight and doesn’t wobble.

Pro Tip: If you’re mounting on vinyl siding, use a siding mounting block to prevent damage and ensure a flat surface.

Step 5: Connect the Wires to the Eufy Doorbell

This is the most technical part, but don’t worry—it’s simpler than it looks.

Identify the Wires

You should have two wires coming from the wall:

Front wire: Comes from the doorbell button.
Transformer wire: Comes from the chime or transformer.

It doesn’t matter which wire goes where on the eufy doorbell—the device is designed to work either way. But for consistency, match them as they were on the old doorbell.

Connect the Wires

Strip the wire ends (if needed): About 1/4 inch of bare copper should be exposed. Use wire strippers if the insulation is too long.
Loosen the terminal screws on the eufy doorbell: There are two small screws on the back of the device.
Insert each wire into a terminal: Push the bare end under the screw and tighten it firmly. Don’t overtighten—just enough to hold the wire securely.
Double-check connections: Gently tug on each wire to ensure it’s tight.

Warning: Do not let the bare wires touch each other or the metal bracket. This can cause a short circuit.

Step 6: Attach the Eufy Doorbell to the Bracket

With the wires connected, it’s time to mount the doorbell.

Secure the Device

Align the doorbell with the bracket: Slide the top of the doorbell into the bracket’s hooks.
Push the bottom into place: It should snap securely.
Tighten the security screw: Use the small screw provided to lock the doorbell in place. This prevents theft or tampering.

Pro Tip: If the doorbell feels loose, check that the wires aren’t pulling it down. You may need to tuck excess wire into the wall cavity.

Step 7: Restore Power and Test

You’re almost done! Now it’s time to power up and test everything.

Turn the Power Back On

Go to the breaker box and turn the doorbell breaker back ON.
Wait 30–60 seconds: The eufy doorbell needs time to boot up.
Check the LED light: A solid blue light means it’s powered and ready to connect.

Test the Doorbell

Press the doorbell button: The chime should sound inside the house.
Open the eufy Security app: You should see a live video feed.
Test two-way audio: Tap the microphone icon and speak. You should hear yourself through the doorbell’s speaker.
Check motion detection: Walk in front of the doorbell. You should receive a notification on your phone.

If everything works, congratulations—you’ve successfully installed your eufy doorbell wired!

Step 8: Set Up the Eufy Security App

The app is where you control your doorbell, view recordings, and customize settings.
