How to Raise Nest Hello Doorbell: A Complete Step-by-Step Guide
So you’ve got your shiny new Nest Hello doorbell—congratulations! It’s a smart upgrade that brings peace of mind, real-time alerts, and crisp video footage right to your phone. But here’s the thing: how high should you mount it? And more importantly, how do you raise your Nest Hello doorbell safely and effectively to get the best performance?
Whether you’re replacing an old doorbell or installing Nest Hello for the first time, getting the height and angle right is crucial. Mount it too low, and you risk missing visitors or getting false alerts from passing cars. Mount it too high, and facial recognition suffers. The sweet spot? Between 48 and 60 inches from the ground. But raising your Nest Hello isn’t just about height—it’s about wiring, alignment, testing, and fine-tuning. In this guide, we’ll walk you through every step to help you raise your Nest Hello doorbell the right way, so you get the most out of your smart home investment.
Why Height Matters for Your Nest Hello Doorbell
Before we dive into the installation, let’s talk about why height is so important. The Nest Hello is packed with advanced features like HD video, night vision, person detection, and two-way audio. But all of these rely on one thing: a clear, unobstructed view of your doorstep.

When your doorbell is mounted too low—say, at 36 inches—it’s likely to capture more of the ground, shoes, or even pets. This can trigger unnecessary motion alerts and make it harder for the camera to recognize faces. On the other hand, if it’s mounted too high—above 60 inches—the angle becomes too steep, and visitors’ faces may appear distorted or cut off.
The ideal height range of 48–60 inches ensures that:
- The camera captures faces at eye level when someone approaches.
- Motion detection zones are focused on the walkway and porch, not the street.
- Night vision and HDR work effectively without overexposure from sky glare.
- Two-way audio picks up voices clearly without echo or distortion.
Think of it like setting up a security camera: you want the lens to see what matters most—people—not pavement or passing cars. Raising your Nest Hello to the right height is the first step toward smarter, more reliable home security.
Tools and Materials You’ll Need
Before you start unscrewing your old doorbell, make sure you have the right tools on hand. Rushing into installation without preparation can lead to mistakes, damaged wiring, or even electrical hazards. Here’s what you’ll need:
- Nest Hello doorbell kit (includes the doorbell, mounting plate, screwdriver, and wire nuts)
- Voltage tester (non-contact type recommended)
- Screwdriver set (Phillips and flathead)
- Drill and drill bits (for mounting screws)
- Level (to ensure the doorbell is straight)
- Pencil or marker (for marking drill points)
- Wire strippers (if you need to trim or re-strip wires)
- Nest wedge kit (optional) – useful if your wall is angled or uneven
- Smartphone with Google Home app installed
Having these tools ready will make the process smoother and safer. If you’re not comfortable working with electrical wiring, consider hiring a licensed electrician—especially if your current doorbell setup is outdated or you’re unsure about voltage levels.
Step 1: Turn Off Power and Test Wiring
Safety first! Even though doorbells use low voltage, it’s still important to turn off the power before you begin. Here’s how to do it safely:
Locate Your Doorbell Transformer
The transformer is usually found in your basement, garage, or near your electrical panel. It converts standard household voltage (120V) down to 16–24V AC, which powers your doorbell. Look for a small box with wires leading to your doorbell circuit.
Turn Off the Circuit Breaker
Find the breaker that controls your doorbell circuit and switch it off. If you’re not sure which one it is, turn off the main breaker to be safe. Use a non-contact voltage tester to confirm that power is off at the doorbell wires.
Remove the Old Doorbell
Unscrew the existing doorbell from the wall. Gently pull it away to expose the two wires connected to the back. Take a photo of the wiring setup for reference. Then, disconnect the wires by loosening the screws or removing wire nuts.
Test the Voltage
Even with the power off, use your voltage tester to double-check that no current is flowing. Then, turn the power back on briefly to test the voltage across the two wires with a multimeter. Nest Hello requires 16–24V AC and at least 20VA (volt-amperes) of power. If your transformer outputs less than 16V, you may need to upgrade it.
Pro Tip: If your current doorbell chimes when you press the button, your wiring is likely compatible. If not, you might need a new transformer or a mechanical chime that works with Nest Hello.
Step 2: Choose the Right Mounting Location
Now that the old doorbell is off and the wiring is confirmed, it’s time to decide where to mount your Nest Hello. The goal is to find a spot that’s:
- Between 48 and 60 inches from the ground
- Centered on the door or slightly offset for better angle
- Protected from direct sunlight and rain (if possible)
- Close enough to existing wires for easy connection
Consider the Camera Angle
The Nest Hello has a 160-degree diagonal field of view, but you still want to avoid pointing it directly at the sky or a bright window. A slight downward tilt (about 10–15 degrees) helps reduce glare and keeps the focus on the walkway.
Check for Obstructions
Look for things that might block the view: door frames, plants, mailboxes, or overhangs. If your porch has a low ceiling, make sure the doorbell isn’t mounted too high where it could be bumped or obscured.
Use a Wedge Kit for Angled Walls
If your wall is slanted or you’re mounting on a corner, the Nest wedge kit can help level the doorbell. The kit includes angled mounts that let you adjust the camera angle without tilting the entire unit. This is especially useful for brick, stone, or uneven surfaces.
Once you’ve found the perfect spot, use a pencil to mark the screw holes. Hold the mounting plate against the wall and use a level to make sure it’s straight. Double-check the height with a tape measure—aim for 52 inches as a good middle ground.
Step 3: Install the Mounting Plate
With your location marked, it’s time to secure the mounting plate. This plate holds the Nest Hello in place and connects to the wiring.
Drill Pilot Holes
Use a drill bit slightly smaller than your mounting screws to create pilot holes at the marked spots. This prevents the wall from cracking, especially if you’re drilling into brick or concrete. For masonry, use a masonry bit and wall anchors.
Attach the Mounting Plate
Line up the plate with the holes and secure it with the provided screws. Make sure it’s tight and level. If you’re using a wedge kit, attach the wedge to the wall first, then screw the mounting plate onto the wedge.
Connect the Wires
Now, connect the two doorbell wires to the terminals on the back of the mounting plate. It doesn’t matter which wire goes where—Nest Hello is not polarity-sensitive. Strip about 1/4 inch of insulation from each wire if needed, then wrap them around the screws and tighten. Use wire nuts if the connections feel loose.
Pro Tip: If your wires are too short, you can extend them with additional 18- or 20-gauge doorbell wire. Just make sure the connections are secure and insulated.
Step 4: Attach the Nest Hello Doorbell
With the mounting plate secured and wired, it’s time to attach the Nest Hello 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. You should feel it lock securely.
Secure with Security Screw
Use the included security screw and the special screwdriver (or a small flathead) to tighten the screw at the bottom of the doorbell. This prevents theft and ensures the unit stays in place.
Turn Power Back On
Go back to your breaker panel and turn the power back on. The Nest Hello should light up with a blue ring, indicating it’s powering on and connecting to Wi-Fi.
If the light doesn’t come on, double-check your wiring and voltage. If it flashes yellow, it’s in setup mode and ready to be configured in the app.
Step 5: Set Up in the Google Home App
Now that your Nest Hello is powered and mounted, it’s time to complete the setup using the Google Home app.
Open the Google Home App
Launch the app on your smartphone. If you don’t have it, download it from the App Store or Google Play. Sign in with your Google account.
Tap the Plus (+) Icon
Select “Set up device” and then “New device.” The app will search for nearby Nest devices. When your Nest Hello appears, tap it to begin setup.
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the doorbell or the quick start guide. This links the device to your account.
Connect to Wi-Fi
Choose your home Wi-Fi network and enter the password. Nest Hello supports 2.4 GHz networks (and some 5 GHz, depending on model). Make sure your signal is strong at the doorbell location—consider a Wi-Fi extender if needed.
Name Your Doorbell
Give it a name like “Front Door” or “Main Entrance” so you can easily identify it in the app.
Test the Features
Once setup is complete, test the live view, two-way audio, and motion detection. Walk in front of the doorbell to trigger a notification. Adjust motion zones in the app if needed to reduce false alerts.
Step 6: Fine-Tune the Angle and Settings
Even with perfect mounting, you might need to tweak the angle or settings for optimal performance.
Adjust the Tilt
If the camera is pointing too high or too low, you can slightly adjust the mounting plate or use the wedge kit to fine-tune the angle. The goal is to see the walkway and the top of visitors’ heads.
Set Motion Zones
In the Google Home app, go to your doorbell settings and select “Motion zones.” Draw zones to focus on the porch and ignore areas like the street or driveway. This reduces unnecessary alerts.
Enable Familiar Face Alerts (Optional)
If you have a Nest Aware subscription, you can enable Familiar Face Detection. The doorbell will learn to recognize family members and send personalized alerts.
Adjust Night Vision and HDR
These settings are usually automatic, but you can tweak them in the app if the video looks too dark or washed out.
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 Power On
- Check that the breaker is on and the transformer is providing 16–24V AC.
- Verify wire connections are tight and not touching each other.
