Before you touch a single screw, gather your tools and materials. Having everything ready saves time and frustration.
Here’s what you’ll need:
– Google Doorbell (wired or battery model)
– Screwdriver (Phillips head)
– Drill and drill bits (if mounting on brick, stucco, or concrete)
– Voltage tester (non-contact type recommended)
– Wire strippers (if reusing old wires)
– Level (to keep the doorbell straight)
– Smartphone with Google Home app installed
– Wi-Fi network (2.4 GHz or 5 GHz—check your model’s requirements)
– Optional: Wall anchors, silicone sealant (for outdoor protection)
Pro tip: If you’re replacing an existing doorbell, take a photo of the wiring before disconnecting anything. This helps you remember which wire goes where.
Step 1: Turn Off the Power
Safety first! Electricity and water don’t mix—and neither do live wires and fingers.
Locate Your Circuit Breaker
Go to your home’s electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “doorbell,” “front door,” or something similar. If you can’t find it, turn off the main breaker to be safe.
Test the Wires
Even after turning off the breaker, use a non-contact voltage tester to double-check that no current is flowing to the doorbell wires. Touch the tester to each wire—if it beeps or lights up, the power is still on. Go back and flip the correct breaker.
Never skip this step. A small shock might not seem like a big deal, but it can damage your doorbell or worse—cause injury.
Step 2: Remove the Old Doorbell (If Applicable)
If you’re replacing an existing doorbell, you’ll need to remove it first.
Unscrew the Faceplate
Use your screwdriver to remove the screws holding the old doorbell in place. Gently pull the faceplate away from the wall.
Disconnect the Wires
You’ll see two wires—usually black and white, or red and white. Loosen the terminal screws and carefully pull the wires free. Don’t let them fall back into the wall!
If the wires are short, use wire strippers to expose about 1/4 inch of fresh copper. This ensures a solid connection with your new doorbell.
Remove the Old Mounting Plate
Unscrew and remove the old mounting bracket. Clean the area if there’s paint or debris.
Now you’re ready for the Google Doorbell!
Step 3: Check Compatibility and Power Requirements
Not all doorbells work with all homes. Google Doorbell (wired models) need a transformer that delivers 8–24 volts AC. Most older doorbells use 16V, which is perfect.
How to Check Your Transformer
The transformer is usually located near your doorbell chime inside the house, or in the basement, attic, or garage. It’s a small metal box with wires coming out.
Look for a label that shows the voltage (V) and amperage (VA). For example, “16V 10VA” is common and works well.
If your transformer is below 8V, your doorbell may not get enough power. If it’s above 24V, you could damage the device. In either case, consult an electrician.
Battery vs. Wired Models
– Wired Google Doorbell: Needs constant power from your home’s wiring. Best for reliable performance and no charging.
– Battery Google Doorbell: Runs on rechargeable batteries. Easier to install but needs charging every few months.
If you choose the battery model, you can still connect it to existing wires for trickle charging—this extends battery life.
Step 4: Attach the Mounting Plate
The mounting plate is the backbone of your doorbell. If it’s not secure, the whole thing can wobble or fall.
Position the Plate
Hold the Google Doorbell mounting plate against the wall where you want to install it. Use a level to make sure it’s straight. Mark the screw holes with a pencil.
Ideal height: 48–60 inches from the ground. This gives a good view of visitors and packages.
Drill Pilot Holes (If Needed)
If you’re mounting on wood, you can screw directly. For brick, stucco, or concrete, drill pilot holes using a masonry bit. Insert wall anchors for extra grip.
Secure the Plate
Line up the plate with the holes and screw it in tightly. Don’t overtighten—this can crack the plastic.
Pro tip: If you’re worried about water damage, apply a small bead of silicone sealant around the edges of the plate before attaching it.
Step 5: Connect the Wires
Now for the electrical part—don’t panic, it’s simple.
Identify the Wires
You should have two wires: one from the doorbell transformer (usually labeled “Front”) and one from the chime. It doesn’t matter which wire goes where—Google Doorbell is non-polarized.
Attach to the Terminal Screws
Loosen the two terminal screws on the back of the Google Doorbell or mounting plate. Insert one wire under each screw and tighten firmly. Make sure no bare wire is exposed outside the terminal.
If your wires are too short, use wire nuts to extend them—but only if you’re confident in your skills. Otherwise, call an electrician.
Optional: Use the Included Jumper Wire
Some models come with a small jumper wire. If your chime doesn’t ring with the new doorbell, connect this wire across the chime terminals to complete the circuit.
Step 6: Attach the Google Doorbell
With the wires connected and the plate secure, it’s time to snap on the doorbell.
Align and Snap
Hold the Google Doorbell so the pins on the back align with the slots on the mounting plate. Gently press until it clicks into place.
Secure with Screws
Use the provided security screw and screwdriver (or a small hex key) to fasten the doorbell to the plate. This prevents theft—some models even alert you if someone tries to remove it.
Step 7: Restore Power and Test
You’re almost done!
Turn the Power Back On
Go to your breaker panel and flip the doorbell circuit back on.
Listen for the Chime
Press the doorbell button. You should hear your indoor chime ring. If not, double-check the wiring and jumper connection.
Check the Light
The doorbell should light up when powered. A solid white or green light means it’s receiving power and connecting to Wi-Fi.
Step 8: Set Up in the Google Home App
Hardware is done—now let’s get it online.
Open the Google Home App
Download it from the App Store or Google Play if you haven’t already. Sign in with your Google account.
Tap “+” to Add a Device
Select “Set up device” > “New device.” The app will search for nearby devices.
Scan the QR Code
Hold your phone up to the QR code on the back of the doorbell or in the box. The app will recognize it and guide you through setup.
Connect to Wi-Fi
Choose your home Wi-Fi network and enter the password. Make sure you’re on a 2.4 GHz network if your doorbell doesn’t support 5 GHz.
Name Your Doorbell
Give it a name like “Front Door” or “Porch.” This helps if you have multiple cameras.
Adjust Settings
Enable motion detection, person alerts, and package detection. You can also set activity zones to ignore trees or sidewalks.
Test Live View
Tap the doorbell in the app and select “Live view.” You should see a clear video feed. Wave at the camera to test motion alerts.
Step 9: Fine-Tune and Optimize
Your doorbell is working—great! Now let’s make it even better.
Adjust the Angle
If the view is too high or low, loosen the security screw slightly and tilt the doorbell. Retighten when satisfied.
Enable Quiet Time
In the app, set “Quiet Time” so alerts don’t disturb you at night.
Share Access
Invite family members by going to “Settings” > “People” > “Invite.” They’ll get their own alerts and live view.
Check Battery (If Applicable)
For battery models, check the charge level in the app. If it’s low, remove the doorbell and charge it via USB.
