How to Install Nest Doorbell with No Existing Doorbell
So, you’ve decided to upgrade your home security with a Nest Doorbell—but you don’t have an existing doorbell. No problem! Many modern homes, especially newer builds or rentals, don’t come with traditional doorbells. The good news? Google designed the Nest Doorbell (both the battery and wired versions) to work in just about any setup, even without pre-existing wiring.
In this complete guide, we’ll walk you through every step of installing a Nest Doorbell when there’s no existing doorbell—no wires, no chime, no problem. Whether you’re going with the battery-powered Nest Doorbell (battery) or the wired Nest Doorbell (wired), we’ve got you covered. You’ll learn how to choose the right model, gather the right tools, mount the device safely, connect it to your Wi-Fi, and set up alerts so you never miss a visitor again.
By the end of this guide, you’ll have a fully functional smart doorbell that sends real-time alerts, records HD video, and lets you talk to visitors from anywhere—all without needing an old-school doorbell system.
Step 1: Choose the Right Nest Doorbell Model

Before you start installing, you need to pick the right Nest Doorbell for your home. Google offers two main models:
- Nest Doorbell (battery): Runs on a rechargeable battery. Ideal if you don’t have wiring or want a quick, flexible install.
- Nest Doorbell (wired): Requires a low-voltage power source (like a transformer). Best if you want continuous power and don’t mind a bit more setup.
Since you don’t have an existing doorbell, the battery model is often the easiest choice. It doesn’t require any electrical work, and you can place it almost anywhere near your front door. However, if you’re comfortable with basic wiring or have access to a power source (like an outdoor outlet or low-voltage transformer), the wired model offers uninterrupted power and avoids the need to recharge.
Tip: If you’re unsure, go with the battery version. It’s more forgiving for first-time installers and works great in most homes.
What’s in the Box?
No matter which model you choose, your Nest Doorbell box should include:
- Nest Doorbell unit
- Mounting plate
- Screws and wall anchors
- Chime connector (for wired models)
- Rechargeable battery (for battery models)
- USB-C charging cable (for battery models)
- Quick start guide
Double-check everything before you begin. If anything’s missing, contact Google Support right away.
Step 2: Gather Your Tools and Supplies
You don’t need a full toolbox, but having the right items on hand will make installation smoother. Here’s what you’ll need:
- Smartphone or tablet: With the Google Home app installed (download from the App Store or Google Play).
- Drill and drill bits: For mounting the doorbell. A 3/16” bit works well for most walls.
- Screwdriver: Phillips head, usually #2.
- Level: To ensure your doorbell is straight.
- Pencil: For marking drill spots.
- Measuring tape: To find the right height and angle.
- Wi-Fi network name and password: You’ll need this during setup.
- Optional: Stud finder: If you’re mounting on wood or need extra support.
If you’re installing the wired model and need to run power, you might also need wire strippers, electrical tape, and a voltage tester—but we’ll cover that in a later step.
Step 3: Plan Your Installation Location
Where you mount your Nest Doorbell matters—a lot. A poor placement can lead to blind spots, false alerts, or weak Wi-Fi signals. Follow these tips to find the perfect spot:
Height and Angle
Mount your doorbell between 48 and 60 inches from the ground. This height captures most visitors’ faces and avoids interference from pets or kids.
Angle the doorbell slightly toward the walkway or driveway. This improves motion detection and ensures the camera sees people approaching, not just standing still.
Wi-Fi Signal Strength
Your doorbell needs a strong Wi-Fi connection to stream video and send alerts. Before drilling, test your Wi-Fi signal at the installation spot.
Use your phone to check signal strength—look for at least 2–3 bars. If the signal is weak, consider:
- Moving your router closer to the front door
- Using a Wi-Fi extender or mesh system
- Choosing a different mounting location with better coverage
Pro Tip: The Google Home app includes a signal strength checker during setup. Use it to confirm your spot is good before mounting.
Power Source (For Wired Models)
If you’re using the wired Nest Doorbell, you’ll need a power source. Look for:
- An existing low-voltage doorbell transformer (even if no doorbell was installed)
- An outdoor electrical outlet (with weatherproof cover)
- A nearby indoor outlet you can route wire to (with proper conduit and safety precautions)
If you don’t have any of these, the battery model is your best bet.
Step 4: Install the Mounting Plate
Now it’s time to mount the doorbell. Follow these steps carefully to ensure a secure and level installation.
Mark the Drill Spots
Hold the mounting plate against the wall at your chosen height. Use a level to make sure it’s straight. Mark the two screw holes with a pencil.
Tip: If you’re mounting on brick, stucco, or concrete, use wall anchors for extra support.
Drill the Holes
Drill pilot holes at the marked spots. Use a drill bit slightly smaller than your screws to ensure a tight fit.
If you’re using wall anchors, tap them gently into the holes with a hammer.
Secure the Mounting Plate
Line up the mounting plate with the holes and screw it into place. Don’t overtighten—just snug enough to hold firmly.
Connect Wires (Wired Models Only)
If you’re installing the wired Nest Doorbell and have access to power:
- Turn off power at the circuit breaker for safety.
- Run low-voltage wire from your power source to the mounting plate.
- Strip about 1/4 inch of insulation from each wire end.
- Connect the wires to the terminals on the back of the doorbell (polarity doesn’t matter).
- Use the included chime connector if you want to connect to an indoor chime (optional).
Warning: If you’re not comfortable working with electricity, hire a licensed electrician. Safety first!
Step 5: Attach the Nest Doorbell
With the mounting plate in place, it’s time to attach the doorbell.
For Battery Models
- Insert the rechargeable battery into the doorbell (if not already installed).
- Align the doorbell with the mounting plate.
- Slide it down until it clicks into place.
- Use the included security screw and screwdriver to lock it in (prevents theft).
For Wired Models
- Connect the wires to the doorbell’s terminals.
- Attach the doorbell to the mounting plate and slide down to lock.
- Secure with the security screw.
Note: The doorbell will power on automatically once connected (wired) or when the battery is inserted (battery).
Step 6: Set Up the Nest Doorbell in the Google Home App
Now for the fun part—connecting your doorbell to your phone and home network.
Download and Open the Google Home App
If you haven’t already, download the Google Home app on your smartphone or tablet. It’s free and available for iOS and Android.
Sign in with your Google account. If you don’t have one, create it—it’s required for setup.
Add Your Doorbell
- Tap the “+” icon in the top-left corner.
- Select “Set up device.”
- Choose “New device.”
- Follow the on-screen prompts to scan the QR code on your doorbell (located on the back or in the box).
The app will guide you through connecting to your Wi-Fi network. Enter your network name and password when prompted.
Complete the Setup
The app will:
- Test your Wi-Fi connection
- Update the doorbell’s software (if needed)
- Walk you through basic settings like motion zones and alert preferences
Take your time with these settings. You can always change them later, but it’s best to get them right the first time.
Set Up Chime (Optional)
If you want indoor alerts but don’t have a doorbell chime, you have options:
- Nest Chime Connector: Plugs into an outlet and connects to your doorbell wirelessly. Plays a chime when someone rings the bell.
- Smart Speaker: Use a Google Nest Mini or Home speaker to announce visitors. Set this up in the Google Home app under “Routines” or “Alarms & Timers.”
Tip: You can also receive alerts on your phone, tablet, or smart display—no chime needed.
Step 7: Test Your Nest Doorbell
Before you call it a day, test everything to make sure it’s working properly.
Check Video Quality
Open the Google Home app and tap your doorbell. Watch the live video feed. Make sure the image is clear, the lighting is good, and the view covers your desired area.
Test Motion Alerts
Walk in front of the doorbell to trigger a motion alert. You should receive a notification on your phone within a few seconds.
Test Two-Way Audio
Tap the microphone icon in the app and speak. Ask someone near the doorbell to listen. You should be able to hear each other clearly.
Test the Doorbell Button
Press the button on the doorbell. You should see a notification on your phone and hear a chime (if connected).
If anything isn’t working, don’t panic—check the troubleshooting section below.
