Step 1: Check Compatibility and Power Requirements

Not all doorbells are created equal—and neither are home electrical systems. Before removing your old doorbell, it’s essential to verify that your home can support the Merkury Smart Doorbell.

Check Your Existing Doorbell Wiring

Most traditional doorbells use low-voltage AC wiring connected to a transformer. The Merkury Smart Doorbell requires 16 to 24 volts AC to operate properly. Here’s how to check:

Turn off power to the doorbell at the circuit breaker.
Remove the existing doorbell button from the wall.
Carefully disconnect the two wires and separate them so they don’t touch.
Turn the power back on briefly and use a voltage tester to measure the voltage across the wires.
If the reading is between 16V and 24V AC, you’re good to go. If it’s below 16V, your transformer may be too weak and needs upgrading.

Note: If you don’t have existing wiring, you’ll need to run new low-voltage wires from your doorbell transformer to the front door. This may require professional help, especially if drilling through walls or siding.

Verify Chime Compatibility

The Merkury doorbell works with most mechanical chimes (the kind with metal bars that ring). However, if you have a digital chime (plays recorded sounds) or a wireless chime, you may need to bypass it or use the included chime module.

To test compatibility:

Open your indoor chime unit and check the wiring.
Look for labels like “Front,” “Trans,” or “Transformer.”
If you see complex circuitry or a battery compartment, it’s likely digital—consult the Merkury support page for compatible models.

Pro Tip: If your chime isn’t compatible, you can still use the doorbell—just rely on mobile notifications and the built-in speaker. Or, replace the chime with a compatible mechanical one.

Step 2: Turn Off Power and Remove Old Doorbell

Safety first! Working with electricity—even low voltage—can be dangerous if not handled properly.

Turn Off the Circuit Breaker

Locate your home’s electrical panel and find the breaker labeled “Doorbell,” “Chime,” or “Front Door.” If there’s no label, turn off the main breaker to be safe.

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

Remove the Old Doorbell Button

Unscrew the old doorbell from the wall.
Gently pull it away to expose the two wires.
Loosen the terminal screws and disconnect the wires.
Cap the wires with wire nuts or electrical tape to prevent them from touching.

Important: Don’t let the wires fall back into the wall. Use a piece of tape to hold them in place while you work.

Step 3: Install the Mounting Plate

The Merkury Smart Doorbell comes with a sturdy mounting plate that attaches to your wall. Proper alignment ensures a clean look and optimal camera angle.

Position the Mounting Plate

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

Pro Tip: The ideal height is about 48 inches from the ground—eye level for most adults. Avoid placing it too high or too low, as this can affect video quality and motion detection.

Drill and Secure the Plate

Drill pilot holes at the marked spots.
If mounting on brick, stucco, or concrete, use wall anchors.
Secure the mounting plate with the provided screws.
Ensure it’s tight and doesn’t wobble.

Optional: If your wall is uneven or you want a more secure fit, use silicone caulk around the edges to seal gaps and prevent moisture intrusion.

Step 4: Connect the Wires to the Doorbell

Now it’s time to wire the Merkury Smart Doorbell. Don’t worry—it’s simpler than it sounds.

Prepare the Wires

Strip about 1/4 inch of insulation from the ends of the two doorbell wires.
Twist the exposed copper strands to prevent fraying.

Attach Wires to the Doorbell

Locate the two terminal screws on the back of the Merkury doorbell (usually labeled “Front” and “Trans”).
Loosen the screws slightly.
Insert one wire under each screw and tighten securely.
Ensure no bare wire is exposed outside the terminals.

Important: The Merkury doorbell is not polarity-sensitive, so it doesn’t matter which wire goes where. However, keep them separate to avoid short circuits.

Secure the Doorbell to the Mounting Plate

Align the doorbell with the mounting plate.
Slide it down until it clicks into place.
Use the included security screw to lock it in (prevents theft).

Pro Tip: If the doorbell feels loose, double-check that the wires aren’t pulling it out of alignment. Adjust the wire slack if needed.

Step 5: Install the Chime Module (If Needed)

If you have a mechanical chime, you’ll need to install the included chime module inside your home. This small device ensures the doorbell triggers the chime when pressed.

Locate Your Indoor Chime Box

Find the box where your doorbell chime is installed—usually in a closet, basement, or hallway.

Disconnect the Wires

Turn off power at the breaker (again, for safety).
Open the chime cover.
Identify the two wires connected to the “Front” terminal.
Disconnect them and cap with wire nuts.

Connect the Chime Module

Connect the two wires from the wall to the input terminals on the chime module.
Connect two new wires from the output terminals on the module to the “Front” terminals on the chime.
Secure all connections and close the chime box.

Note: The chime module acts as a relay—it allows the doorbell to communicate with the chime without overloading the circuit.

Step 6: Download the Merkury Smart App

The Merkury Smart app is your control center for the doorbell. It’s available for free on the Apple App Store and Google Play Store.

Download and Install the App

Open your smartphone’s app store.
Search for “Merkury Smart.”
Download and install the app.
Open the app and create an account (or log in if you already have one).

Pro Tip: Use a strong, unique password and enable two-factor authentication for added security.

Step 7: Connect the Doorbell to WiFi

Now comes the fun part—pairing your doorbell with your home network.

Power On the Doorbell

Turn the circuit breaker back on.
Wait 30–60 seconds for the doorbell to power up.
You should see a solid blue light on the front.

Put the Doorbell in Pairing Mode

Press and hold the setup button (usually on the side or back) for 5 seconds.
The light should start blinking blue—this means it’s ready to connect.

Follow the App Instructions

Open the Merkury Smart app.
Tap “Add Device” or the “+” icon.
Select “Doorbell Camera.”
Scan the QR code on the back of the doorbell or enter the serial number manually.
Follow the on-screen prompts to connect to your WiFi network.
Enter your WiFi password when prompted.

Important: The Merkury doorbell only works on 2.4GHz WiFi networks. If your router broadcasts both 2.4GHz and 5GHz under the same name, you may need to temporarily separate them or use a guest network.

Wait for Connection

The app will attempt to connect the doorbell to your network. This can take 1–3 minutes. Once connected, you’ll see a confirmation message and the doorbell light will turn solid green.

Troubleshooting Tip: If connection fails, move closer to your router, restart the doorbell, or reset the network settings in the app.

Step 8: Configure Settings and Test the System

With the doorbell online, it’s time to customize it to your preferences.

Adjust Camera and Motion Settings

In the app, go to “Device Settings.”
Set motion detection sensitivity (low, medium, high).
Define motion zones to avoid alerts from passing cars or trees.
Enable night vision and adjust video quality (HD recommended).

Set Up Notifications

Go to “Notification Settings.”
Choose when to receive alerts (always, only when motion is detected, etc.).
Enable push notifications and email alerts if desired.

Test the Doorbell

Press the doorbell button.
Check that the indoor chime rings (if installed).
Verify that you receive a push notification on your phone.
Open the app and confirm you can see live video and hear audio.
Test two-way talk by speaking through the app.

Pro Tip: Have a friend stand at the door while you test from inside. This helps confirm audio clarity and video angle.
