Before you even think about touching a screwdriver, make sure you have everything you need. Rushing into installation without the right tools or information can lead to frustration—or worse, damage to your doorbell or electrical system.
Here’s a checklist of what you’ll need:
- Nest Hello Video Doorbell kit: This includes the doorbell itself, mounting plate, screw pack, and chime connector.
- Screwdriver (Phillips head): For removing your old doorbell and securing the new mounting plate.
- Drill and drill bits (optional): Useful if you need to make new holes or adjust the mounting angle.
- Voltage tester: To confirm your doorbell wiring is live and meets Nest’s voltage requirements.
- Smartphone or tablet: You’ll use this to download the Nest app and complete the setup.
- Wi-Fi network: Your home Wi-Fi must support 2.4 GHz (5 GHz is not supported by Nest Hello).
- Ladder (if needed): Depending on your door height, you may need a small ladder to reach the installation spot.
It’s also a good idea to have a helper nearby—especially if you’re working at height or handling wires. Safety first!
Step 1: Check Compatibility
Not every home is ready for the Nest Hello right out of the box. Before you remove your old doorbell, you need to verify that your existing wiring and transformer can support the new device.
Check Your Doorbell Wiring
The Nest Hello requires low-voltage AC wiring (typically two wires) connected to a doorbell transformer. Most homes built after the 1980s have this, but older homes or those with wireless doorbells may not.
To check:
- Remove your existing doorbell button from the wall.
- Look for two thin wires (usually white and red or black) connected to the back.
- If you see wires, great! If not, you may need to run new wiring or consider a battery-powered alternative (note: Nest Hello is wired-only).
Test the Voltage
The Nest Hello needs a transformer that outputs between 16 and 24 volts AC and at least 30 volt-amperes (VA). Too little power, and the doorbell won’t work properly. Too much, and you risk damaging the device.
Here’s how to test:
- Turn off power to the doorbell at the breaker.
- Disconnect the wires from the old doorbell.
- Set your voltage tester to AC voltage.
- Touch the probes to the two doorbell wires.
- Turn the power back on and check the reading.
If the voltage is between 16–24V AC and the transformer is rated 30VA or higher, you’re good to go. If it’s lower, you may need to upgrade your transformer—a job best left to an electrician.
Check Your Chime Compatibility
The Nest Hello works with most mechanical and digital chimes, but some older or incompatible models may not work properly. Nest provides a compatibility tool on their website where you can enter your chime brand and model to check.
If your chime isn’t compatible, don’t worry—the Nest Hello kit includes a chime connector that bypasses the chime and sends the signal directly to the doorbell. We’ll cover how to install it later.
Step 2: Turn Off the Power
This step is non-negotiable. Working with live electrical wires is dangerous and can result in serious injury or damage to your doorbell.
Locate Your Circuit Breaker
Find your home’s main electrical panel. Look for a breaker labeled “doorbell,” “chime,” or something similar. If you can’t find it, turn off the main breaker to be safe.
Test the Wires Again
Even after turning off the breaker, double-check that the wires are not live using your voltage tester. Touch the probes to the two doorbell wires. If the tester shows zero voltage, you’re safe to proceed.
Pro tip: Place a piece of tape over the breaker switch so no one accidentally turns it back on while you’re working.
Step 3: Remove Your Old Doorbell
Now that the power is off and you’ve confirmed compatibility, it’s time to remove the old doorbell.
Unscrew the Old Button
Use your screwdriver to remove the screws holding the old doorbell button to the wall. Gently pull the button away from the wall so you can access the wires.
Disconnect the Wires
Loosen the screws holding the wires in place and carefully remove them. Don’t let the wires fall back into the wall—use a piece of tape to hold them in place or have a helper assist.
Inspect the Mounting Area
Check the condition of the wall and existing mounting holes. If the new Nest Hello mounting plate doesn’t align with the old holes, you may need to drill new ones. The Nest Hello comes with a template to help you mark the correct spots.
Step 4: Install the Nest Hello Mounting Plate
The mounting plate is the backbone of your installation. It holds the doorbell securely and connects the wires.
Position the Mounting Plate
Hold the mounting plate against the wall where you want to install the doorbell. The ideal height is about 5 feet from the ground—this gives the best view of visitors and packages.
Use a level to make sure the plate is straight. If your doorframe is uneven, you may need to angle the plate slightly toward the walkway for better motion detection.
Mark and Drill Holes
If the existing holes don’t align, use the mounting plate as a template to mark new screw locations. Drill pilot holes if needed, especially if you’re mounting into brick, stucco, or concrete.
Secure the Plate
Insert the provided wall anchors (if needed), then screw the mounting plate into place. Make sure it’s tight and secure—this will support the weight of the doorbell.
Connect the Wires
Now it’s time to connect the doorbell wires to the mounting plate.
- Strip about 1/4 inch of insulation from the ends of the wires if needed.
- Loosen the terminal screws on the back of the mounting plate.
- Insert each wire into its respective terminal (it doesn’t matter which wire goes where—Nest Hello is non-polarized).
- Tighten the screws to secure the wires.
Tip: If your chime is incompatible, now is the time to install the chime connector. Simply connect the two wires from your wall to the chime connector, then connect the connector to the mounting plate. This bypasses the chime and sends the signal directly to the doorbell.
Step 5: Attach the Nest Hello Doorbell
With the mounting plate securely in place and wires connected, it’s time to attach the doorbell itself.
Align and Snap Into Place
Hold the Nest Hello so the pins on the back align with the slots on the mounting plate. Gently push it forward until it clicks into place.
Secure with Anti-Theft Screw
Use the small security screw provided in the kit to lock the doorbell to the mounting plate. This prevents thieves from easily removing it.
Turn the Power Back On
Go back to your breaker panel and turn the power back on. The Nest Hello should light up and begin initializing.
Step 6: Set Up the Nest App
The Nest app is your control center for the doorbell. It guides you through setup, connects to Wi-Fi, and lets you customize settings.
Download the Nest App
If you haven’t already, download the Nest app from the App Store (iOS) or Google Play (Android). Create a Google account if you don’t have one—Nest devices require a Google account to function.
Start the Setup Process
Open the app and tap “Set up a device.” Select “Doorbell” and then “Nest Hello.” The app will prompt you to scan the QR code on the back of your doorbell or enter the serial number manually.
Connect to Wi-Fi
Follow the on-screen instructions to connect your doorbell to your home Wi-Fi network. Remember: Nest Hello only works on 2.4 GHz networks. If your router broadcasts both 2.4 GHz and 5 GHz, make sure you’re connecting to the 2.4 GHz band.
Test the Connection
Once connected, the app will test the video feed. You should see a live view of your front door. If the image is blurry or laggy, check your Wi-Fi signal strength. Consider moving your router or using a Wi-Fi extender if needed.
Pair with Your Chime
If you’re using a compatible chime, the app will guide you through pairing. Press the doorbell button—your chime should ring. If it doesn’t, you may need to adjust settings or use the chime connector.
Customize Settings
Now’s the time to personalize your experience:
- Motion zones: Define areas where you want to receive alerts (e.g., driveway but not street).
- Familiar face alerts: Enable this feature to get notified when family or friends arrive.
- Night vision: Adjust brightness and sensitivity for low-light conditions.
- Activity zones: Set up specific zones for package detection or pet monitoring.
Step 7: Final Testing and Adjustments
Before you call the job done, make sure everything is working perfectly.
Test the Doorbell Button
Press the button and verify that:
- The chime rings (if connected).
- You receive a notification on your phone.
- The live video feed opens quickly.
- Two-way audio works clearly.
Check Motion Detection
Walk in front of the doorbell to test motion alerts. Adjust the sensitivity and zones in the app if you’re getting too many false alarms (e.g., from passing cars or tree branches).
Verify Night Vision
Test the doorbell at night or in low light. The infrared LEDs should activate automatically, providing a clear black-and-white image.
Review Video History
If you have a Nest Aware subscription, check that past events are being recorded and stored properly.
