Before diving into the installation, it’s worth understanding why adding a second doorbell makes sense.
First, **coverage**. A single doorbell only watches one entrance. But homes often have multiple access points—back doors, garages, side gates—where packages are dropped off or visitors arrive. A second Nest Video Doorbell ensures you’re not missing anything.
Second, **convenience**. With two doorbells, you can see who’s at the back door while you’re in the kitchen, or check the side entrance from your phone while relaxing in the living room. No more guessing or running to the window.
Third, **security**. More eyes mean better protection. If someone approaches your home from an unexpected angle, you’ll know immediately. Plus, motion alerts and recorded clips help deter porch pirates and unwanted visitors.
Finally, **flexibility**. Nest Video Doorbells work great in multi-unit buildings, vacation rentals, or homes with separate guest houses. You can manage all devices from one app, making it easy to monitor different areas.
What You’ll Need Before You Begin
Before you start installing your second Nest Video Doorbell, gather the following tools and materials:
- Nest Video Doorbell (2nd gen or later): Choose between the battery-powered or wired model based on your needs.
- Smartphone or tablet: Must have the latest version of the Google Home or Nest app installed.
- Wi-Fi network: A stable 2.4 GHz or 5 GHz connection with strong signal at the installation site.
- Screwdriver: Typically a Phillips head, for mounting the doorbell.
- Drill (optional): Only needed if you’re mounting on brick, concrete, or another hard surface.
- Level: To ensure the doorbell is straight.
- Wire strippers (for wired models): If you’re replacing an existing wired doorbell.
- Chime connector (for wired models): Included with the Nest doorbell kit.
- Battery (for battery models): Fully charged before installation.
Pro tip: If you’re installing the wired version, make sure your existing doorbell transformer provides at least 16–24 volts AC. Most modern systems do, but it’s worth checking to avoid power issues.
Step 1: Choose the Right Location
The first step in installing your second Nest Video Doorbell is picking the perfect spot.
Consider Visibility and Angle
You want the camera to capture a clear view of the entrance. Ideally, mount it at chest height (about 4–5 feet from the ground) and angled slightly downward. This gives the best view of people approaching and packages left at the door.
Avoid placing it too high—it might miss shorter visitors or packages. Also, don’t point it directly at a bright light source like a porch light or the sun, as this can cause glare or overexposure.
Check Wi-Fi Signal Strength
Your doorbell needs a strong Wi-Fi connection to stream video and send alerts. Use your phone to check the signal at the installation site. If it’s weak, consider moving your router, using a Wi-Fi extender, or choosing a location closer to your network.
Nest recommends a minimum signal strength of -65 dBm for reliable performance. You can use a Wi-Fi analyzer app to measure this.
Ensure Power Access (for Wired Models)
If you’re installing the wired version, make sure there’s an existing doorbell transformer and wiring at the location. You’ll need access to the wires behind the old doorbell or a junction box.
For battery models, you don’t need wiring, but you will need to charge the battery every few months. Choose a spot that’s easy to reach for maintenance.
Step 2: Remove the Old Doorbell (If Applicable)
If you’re replacing an existing doorbell, you’ll need to remove it first.
Turn Off Power (Wired Models Only)
Safety first! Turn off the power to your doorbell at the circuit breaker. Use a non-contact voltage tester to confirm the wires are not live before touching them.
Unscrew and Disconnect
Use a screwdriver to remove the old doorbell from the wall. Carefully disconnect the wires—note which wire goes where (usually labeled “Front” and “Trans”). You can take a photo for reference.
If the wires are short, gently pull them out a bit to give yourself more slack. Don’t cut them unless necessary.
Cap the Wires
Twist wire nuts onto the exposed ends to prevent short circuits. Tuck the wires back into the wall if you’re not installing the Nest doorbell immediately.
Step 3: Install the Mounting Plate
Now it’s time to mount the Nest doorbell.
Position the Plate
Hold the mounting plate against the wall where you want the doorbell. Use a level to make sure it’s straight. Mark the screw holes with a pencil.
Drill Pilot Holes (If Needed)
If you’re mounting on wood, you can screw directly into the wall. For brick, stucco, or concrete, drill pilot holes using a masonry bit. Insert wall anchors if necessary.
Secure the Plate
Line up the plate with the holes and screw it into place. Make sure it’s tight and level.
Connect the Wires (Wired Models)
If you’re using the wired version, connect the doorbell wires to the terminals on the back of the mounting plate. It doesn’t matter which wire goes where—Nest doorbells are polarity-independent.
For battery models, skip this step.
Step 4: Attach the Doorbell
With the mounting plate in place, it’s time to attach the doorbell.
Slide It On
Align the doorbell with the mounting plate and slide it down until it clicks into place. You should hear a secure snap.
Secure with Screw (Optional)
For extra security, especially in high-theft areas, use the included security screw to lock the doorbell to the plate. This prevents tampering or theft.
Turn Power Back On (Wired Models)
Go back to your circuit breaker and turn the power back on. The doorbell should light up, indicating it’s receiving power.
Step 5: Set Up in the Nest or Google Home App
Now for the fun part—connecting your new doorbell to your smart home system.
Open the App
Launch the Google Home app (or the Nest app, if you’re still using it). Make sure you’re signed in to the same Google account used for your first doorbell.
Tap the Plus (+) Icon
In the app, tap the “+” icon in the top-left corner and select “Set up device.”
Choose “New Device”
Follow the prompts to add a new device. The app will search for nearby Nest products.
Scan the QR Code
Hold your phone up to the QR code on the back of the doorbell. The app will recognize it and begin setup.
Name Your Doorbell
Here’s a key tip: **Give it a clear, unique name**. Instead of “Nest Doorbell 2,” use something like “Back Door” or “Side Entrance.” This makes it easy to identify in notifications and when viewing live feeds.
Connect to Wi-Fi
Select your Wi-Fi network and enter the password. The doorbell will connect and download any necessary updates.
Complete Setup
Follow the remaining prompts to configure motion zones, alert preferences, and recording settings. You can also choose whether to enable package detection, facial recognition (if available), and more.
Step 6: Test and Adjust Settings
Once setup is complete, it’s time to test everything.
Check Video Quality
Open the app and view the live feed. Make sure the image is clear, the angle is right, and there’s no glare or distortion.
Test Motion Alerts
Walk in front of the doorbell to trigger a motion alert. Check that you receive a notification on your phone and that the clip is recorded.
Adjust Motion Zones
If the doorbell is detecting too much motion (like passing cars or tree branches), go into the app and adjust the motion zones. You can draw custom areas to focus on the walkway or doorstep.
Verify Two-Way Audio
Tap the microphone icon and speak. Ask someone near the doorbell to confirm they can hear you. This is great for talking to delivery drivers or visitors.
Check Night Vision
Test the doorbell at night to ensure the infrared night vision is working. The image should be clear and well-lit in low-light conditions.
Step 7: Manage Multiple Doorbells in the App
With two doorbells now active, you’ll want to manage them efficiently.
Switch Between Cameras
In the Google Home app, tap on the camera feed you want to view. You can easily switch between “Front Door” and “Back Door” with a tap.
Customize Notifications
You can set different notification preferences for each doorbell. For example, you might want instant alerts for the front door but only summary notifications for the back.
Create Routines (Optional)
Use Google Assistant routines to automate actions. For example, “When the back doorbell detects motion after 10 PM, turn on the porch light.”
Share Access
Add family members or roommates to the app so they can view feeds and receive alerts. Go to “Settings” > “Users” > “Invite” and enter their email.
Troubleshooting Common Issues
Even with careful installation, you might run into a few hiccups. Here’s how to fix the most common problems.
Doorbell Won’t Connect to Wi-Fi
- Make sure you’re using a 2.4 GHz network (some older Nest models don’t support 5 GHz).
- Move your router closer or use a Wi-Fi extender.
- Restart the doorbell by removing it from the mount and reinserting it.
No Power (Wired Models)
- Double-check that the power is on at the breaker.
- Verify the wires are securely connected to the mounting plate.
