Let’s get started!

Why Hardwire Your Eufy Doorbell?

Before diving into the installation, it’s important to understand why hardwiring is beneficial. While Eufy offers battery-powered doorbells, hardwiring provides several advantages:

• Continuous power: No more worrying about charging batteries or replacing them every few months.
• Stable performance: Hardwired doorbells don’t experience power drops that can affect video quality or connectivity.
• Full feature access: Some advanced features, like continuous recording or enhanced motion detection, work best with a constant power supply.
• No maintenance: Once installed, a hardwired doorbell requires minimal upkeep.

If your Eufy model supports hardwiring—most do—it’s worth the effort. Just make sure your home has existing doorbell wiring and a compatible transformer.

Check Compatibility and Requirements

Not all Eufy doorbells are designed for hardwiring, and not all homes are set up for it. Before you begin, confirm the following:

1. Confirm Your Eufy Model Supports Hardwiring

Most Eufy video doorbells, including the Eufy Video Doorbell 2K (Wired), Eufy Video Doorbell Dual, and Eufy Video Doorbell Slim, are built for hardwired installation. However, some battery-only models cannot be hardwired. Check your product manual or the Eufy website to verify.

2. Check for Existing Doorbell Wiring

Open your current doorbell button (if you have one) and look for two low-voltage wires connected to the back. These are typically 16–24 AWG wires running from the doorbell transformer to the chime and doorbell.

If you don’t have existing wires, hardwiring will require running new ones—a more complex job that may need professional help.

3. Verify Transformer Voltage

Eufy doorbells require a transformer that outputs between 16V and 24V AC, with at least 10VA (volt-amperes) of power. Most older doorbells use 16V transformers, which are usually sufficient.

To check:

• Locate your doorbell transformer—commonly found in the basement, garage, or near the electrical panel.
• Look for a label indicating voltage and VA rating.
• If unsure, use a multimeter to test the voltage across the transformer terminals.

If your transformer is below 16V or under 10VA, you may need to upgrade it for reliable performance.

4. Ensure Your Chime Is Compatible

Some mechanical chimes may not work well with smart doorbells due to power draw differences. Eufy recommends using their compatible chime or a digital chime. If your existing chime is mechanical and loud, it might still work—but test it during installation.

Gather the Right Tools and Materials

Having the right tools makes the installation smoother and safer. Here’s what you’ll need:

• Screwdrivers: Phillips and flathead for removing covers and mounting hardware.
• Voltage tester or multimeter: To confirm power is off and check transformer output.
• Wire strippers: For removing insulation from wires.
• Drill and drill bits: For mounting the doorbell bracket (if needed).
• Wire nuts: To secure wire connections.
• Electrical tape: For extra insulation.
• Pencil or marker: For marking drill points.
• Ladder: To safely reach the doorbell location.
• Eufy doorbell mounting kit: Usually included with your doorbell.

Optional but helpful:

• Fish tape (for running new wires)
• Cable clips or conduit (to secure wires)
• Smartphone or tablet (to test the doorbell app)

Turn Off Power and Prepare the Area

Safety is critical when working with electricity. Follow these steps to protect yourself and your equipment.

1. Turn Off Power at the Breaker

Never work on doorbell wiring while it’s live. Even though it’s low voltage, it can still cause shocks or damage your doorbell.

• Go to your home’s electrical panel (breaker box).
• Locate the circuit that powers your doorbell—this may be labeled or you may need to test circuits by turning them off one by one.
• Turn off the breaker.
• Use a voltage tester at the doorbell to confirm no power is present.

2. Remove the Old Doorbell (If Applicable)

If you’re replacing an existing doorbell:

• Unscrew the old doorbell button from the wall.
• Carefully pull it away to expose the wires.
• Disconnect the wires by loosening the terminal screws or removing wire nuts.
• Cap the wires with wire nuts to prevent them from touching.

Set the old doorbell aside—you won’t need it anymore.

3. Inspect the Wiring

Check the condition of the wires:

• Look for fraying, corrosion, or damage.
• If wires are damaged, trim them back and strip fresh ends (about 1/2 inch of insulation).
• Ensure both wires are long enough to reach the new doorbell.

If the wires are too short, you may need to extend them using wire connectors and additional low-voltage wire.

Install the Eufy Doorbell Mounting Bracket

The mounting bracket ensures your doorbell is secure and properly aligned.

1. Position the Bracket

Hold the Eufy mounting bracket against the wall where you want to install the doorbell. Ideal placement is at eye level (about 48 inches from the ground) and centered on the door.

Use a level to ensure it’s straight. Mark the screw holes with a pencil.

2. Drill Pilot Holes

If mounting into wood or drywall:

• Use a drill bit slightly smaller than the screws provided.
• Drill pilot holes at the marked spots.

For brick or concrete, use a masonry bit and wall anchors.

3. Secure the Bracket

Align the bracket with the holes and screw it into place. Make sure it’s tight and level.

Some Eufy models include a wedge bracket for angled mounting (e.g., if your door is recessed). Use this if needed for better camera view.

Connect the Wires to the Doorbell

Now it’s time to connect your home’s wiring to the Eufy doorbell.

1. Prepare the Wires

Strip about 1/2 inch of insulation from the ends of the two doorbell wires. Twist the exposed copper strands to prevent fraying.

2. Attach Wires to the Doorbell

Eufy doorbells have two terminal screws or push-in connectors on the back:

• One wire goes to the “Front” terminal.
• The other goes to the “Trans” terminal.

It doesn’t matter which wire goes where—Eufy doorbells are not polarity-sensitive. However, for consistency, match the existing wiring (e.g., red to front, white to trans).

Tighten the screws securely or push the wires into the connectors until they’re snug.

3. Secure the Doorbell to the Bracket

Slide the doorbell onto the mounting bracket until it clicks into place. Some models require you to tighten a security screw at the bottom to prevent theft.

Restore Power and Test the Doorbell

With everything connected, it’s time to power up and test.

1. Turn the Breaker Back On

Return to the electrical panel and turn the breaker back on.

2. Wait for the Doorbell to Boot Up

The Eufy doorbell will power on and begin initializing. This may take 30–60 seconds. You’ll see LED lights flashing—refer to your manual for status codes.

3. Open the Eufy App

Download the Eufy Security app (iOS or Android) if you haven’t already. Create an account or log in.

4. Add the Doorbell to the App

Follow the in-app setup:

• Tap “Add Device” and select your doorbell model.
• Scan the QR code on the doorbell or enter the serial number.
• Follow the prompts to connect to Wi-Fi and complete setup.

5. Test Functionality

Once connected:

• Press the doorbell button—your phone should receive a notification.
• Check video quality and audio in the app.
• Test two-way talk by speaking through the app.
• Verify motion detection by walking in front of the doorbell.

If everything works, your installation is successful!
