Before you begin, gather these tools and materials. Most are included in the Nest Hello box, but it helps to have a few extras on hand.
- Nest Hello Video Doorbell (wired model)
- Existing doorbell wiring (low-voltage, typically 2 wires)
- Phillips head screwdriver (included)
- Wire labels (included)
- Wedge or corner mount (optional, included if needed)
- Drill and drill bits (if mounting on brick, stucco, or concrete)
- Voltage tester (recommended)
- Electrical tape
- Smartphone with Google Home app installed
- Wi-Fi network (2.4 GHz or 5 GHz)
Having everything ready saves time and prevents mid-installation trips to the hardware store.
Step 1: Check Compatibility
Not all homes are ready for the Nest Hello right out of the box. Before you start, confirm your doorbell system meets the basic requirements.
Check Your Doorbell Transformer
The Nest Hello wired model needs a transformer that outputs 16–24 volts AC (alternating current) and at least 8VA (volt-amperes). Most modern doorbells use 16V or 24V transformers, but older homes may have lower voltage.
To check:
- Locate your doorbell transformer. It’s usually near your main electrical panel, in the basement, garage, or utility closet.
- Look for a small metal box with wires connected to it. It often has “16V” or “24V” printed on it.
- If you can’t find it, turn off your doorbell at the breaker and remove the existing doorbell button. Use a voltage tester to check the voltage across the two wires.
If your transformer is below 16V or under 8VA, you may need to upgrade it. A 16V, 30VA transformer is a popular choice and widely available at hardware stores.
Verify Wi-Fi Signal Strength
The Nest Hello needs a strong Wi-Fi connection to stream video and send alerts. Stand at your front door with your phone and check the signal strength.
If your Wi-Fi is weak:
- Move your router closer to the front door.
- Use a Wi-Fi extender or mesh system to boost coverage.
- Ensure your network supports 2.4 GHz (required) or 5 GHz (optional but better for video).
A strong signal ensures smooth video and reliable notifications.
Check for Existing Chime
The Nest Hello works with mechanical (ding-dong) and digital (electronic) chimes. If you have a digital chime, make sure it’s compatible. Most are, but some older models may not work well with smart doorbells.
If your chime doesn’t ring after installation, you may need a Nest Chime Connector (sold separately) or a compatible digital chime.
Step 2: Turn Off Power
Safety first! Working with electrical wiring can be dangerous if the power is on.
Locate the Circuit Breaker
Find the breaker that controls your doorbell. It’s often labeled “doorbell,” “chime,” or “front door.” If not, turn off breakers one by one and test your doorbell until it stops ringing.
Turn Off the Breaker
Switch the breaker to the “off” position. Use a non-contact voltage tester at the doorbell wires to confirm no power is flowing.
Never skip this step—even low-voltage systems can cause shocks or damage your doorbell.
Step 3: Remove Your Old Doorbell
Now it’s time to take down your existing doorbell button.
Unscrew the Old Button
Use a Phillips head screwdriver to remove the two screws holding the doorbell in place. Gently pull the button away from the wall.
Label the Wires
You’ll see two wires connected to the back. Use the wire labels included in the Nest Hello kit to mark them (e.g., “Front” and “Trans”). This helps avoid confusion when connecting the new doorbell.
Tuck Wires Safely
Push the wires back into the wall slightly so they don’t fall in. Don’t cut or strip them yet—just leave them accessible.
Step 4: Prepare the Nest Hello
Unbox your Nest Hello and get it ready for installation.
Check the Kit Contents
Make sure you have:
- Nest Hello doorbell
- Mounting bracket
- Screws and anchors
- Wire labels
- Screwdriver
- Wedge or corner mount (if needed)
Choose the Right Mount
The Nest Hello comes with a flat mounting bracket. If your door is recessed or you want to angle the camera, use the wedge or corner mount.
For example:
- Use the wedge mount if your door is set back from the wall.
- Use the corner mount if installing on a corner or angled surface.
Attach the chosen mount to the back of the Nest Hello using the provided screws.
Step 5: Connect the Wires
This is the most important step—getting the wiring right ensures your doorbell works properly.
Strip the Wire Ends
Use a wire stripper or carefully use scissors to remove about 1/4 inch of insulation from each wire. You should see bare copper.
Attach Wires to the Nest Hello
The Nest Hello has two terminals: one marked “Front” and one marked “Trans.” It doesn’t matter which wire goes where—Nest Hello is polarity-independent.
Loosen the terminal screws, insert the stripped wire ends, and tighten the screws securely. Give the wires a gentle tug to make sure they’re held firmly.
Use Electrical Tape (Optional)
For extra security, wrap the base of the wires with electrical tape to prevent short circuits.
Step 6: Mount the Doorbell
Now it’s time to attach the Nest Hello to your wall.
Position the Doorbell
Hold the doorbell against the wall where you want it. The camera should have a clear view of your doorstep and walkway.
Use a level to make sure it’s straight.
Mark Screw Holes
With the doorbell in place, use a pencil to mark where the screw holes will go.
Drill Pilot Holes (If Needed)
If you’re mounting on brick, stucco, or concrete, drill pilot holes using a masonry bit. Insert wall anchors for a secure fit.
Secure the Doorbell
Line up the mounting bracket with the screw holes and drive the screws in using the included screwdriver. Don’t overtighten—just snug enough to hold the doorbell firmly.
Step 7: Restore Power and Test
You’re almost done! Now it’s time to power up and test your new doorbell.
Turn the Breaker Back On
Go to your electrical panel and switch the doorbell breaker back to “on.”
Wait for the Doorbell to Power Up
The Nest Hello will light up and begin initializing. This may take 30–60 seconds.
Test the Doorbell
Press the button on the Nest Hello. Your indoor chime should ring (if connected), and the doorbell should send a notification to your phone.
If the chime doesn’t ring, check your chime type and consider using a Nest Chime Connector.
Step 8: Set Up in the Google Home App
The final step is connecting your Nest Hello to your Wi-Fi and customizing settings.
Open the Google Home App
Download the Google Home app from the App Store or Google Play if you haven’t already.
Add a New Device
Tap the “+” icon, then “Set up device,” and follow the prompts.
Scan the QR Code
The Nest Hello has a QR code on the back. Use your phone’s camera to scan it. This links the doorbell to your account.
Connect to Wi-Fi
Select your Wi-Fi network and enter the password. The doorbell will connect and download any updates.
Complete Setup
Follow the on-screen instructions to name your doorbell, set up motion zones, and enable notifications.
Customizing Your Nest Hello
Once installed, take time to personalize your doorbell for the best experience.
Adjust Motion Zones
In the Google Home app, go to your doorbell settings and tap “Motion zones.” Draw areas where you want alerts (e.g., your walkway) and exclude areas like the street or sidewalk.
This reduces false alerts from passing cars or animals.
Enable Familiar Face Alerts
Nest Hello can recognize people you know. Add family members and frequent visitors in the app to get personalized alerts like “Mom is at the door.”
Set Activity Zones
Create zones for specific areas, like your porch or driveway, to get targeted notifications.
Enable Two-Walk Talk
Test the two-way audio by speaking through the app. Make sure the microphone and speaker are working clearly.
