What You’ll Need Before Starting
Before you begin the installation, it’s important to gather all the necessary tools and materials. Having everything ready will save time and prevent frustration mid-installation.
Tools and Materials
- Nest Hello doorbell camera
- Smartphone or tablet with the Nest app installed
- Drill with drill bits (for mounting)
- Screwdriver (Phillips head)
- Wire strippers (if using wired power)
- Electrical tape
- Voltage tester (recommended for safety)
- Power source: Either a compatible transformer (16–24V AC) or a Nest plug-in power adapter
- Optional: Junction box or weatherproof enclosure (for clean wiring)
- Optional: Level tool (to ensure straight mounting)
Understanding Your Power Options
Since you don’t have a doorbell, the biggest challenge is providing power to the Nest Hello. Unlike battery-powered doorbells, the Nest Hello requires a constant power supply to function properly—especially for features like continuous video recording and live streaming.
You have two main options:
Option 1: Hardwired Power (Using a Transformer)
If your home has existing low-voltage wiring (even if unused), you can install a doorbell transformer to supply power. This is the most reliable method and recommended for permanent installations.
Option 2: Plug-in Power Adapter
If there’s no wiring at all, you can use the official Nest plug-in power adapter. This plugs into a standard wall outlet and connects to the Nest Hello via a weatherproof cable. It’s ideal for renters or homes without doorbell infrastructure.
We’ll cover both methods in detail below.
Step 1: Choose Your Power Source
The first and most critical step is deciding how you’ll power your Nest Hello. Without power, the device won’t work—no matter how well you mount it.
Option A: Install a Doorbell Transformer (Hardwired)
If you’re comfortable working with electrical systems and your home has a junction box or space near your breaker panel, installing a transformer is a great long-term solution.
What is a doorbell transformer?
A doorbell transformer steps down your home’s standard 120V AC power to a safer 16–24V AC, which is what the Nest Hello needs. Most homes already have one, but if yours doesn’t (or if it’s incompatible), you’ll need to install a new one.
Steps to Install a Transformer:
- Turn off power at the breaker: Safety first! Locate your electrical panel and turn off the circuit that powers the area where you’ll install the transformer.
- Choose a location: The transformer should be installed inside your home, near an electrical outlet or junction box. Common spots include the basement, garage, or utility closet.
- Mount the transformer: Use screws to secure it to a junction box or electrical box. Make sure it’s accessible for future maintenance.
- Connect the wires: Run two low-voltage wires (typically 18–22 gauge) from the transformer to your front door. These will carry power to the Nest Hello.
- Connect to the breaker: Wire the transformer’s input side to a 120V circuit using wire nuts and electrical tape. Follow local electrical codes—consider hiring an electrician if you’re unsure.
- Test the voltage: Use a multimeter to confirm the output is between 16–24V AC.
Tip: If you’re not comfortable working with electricity, hire a licensed electrician. It’s a small cost for peace of mind and safety.
Option B: Use the Nest Plug-in Power Adapter
If you don’t want to deal with wiring or live in a rental, the Nest plug-in power adapter is your best friend. It’s designed specifically for Nest Hello installations without existing doorbell wiring.
What’s included:
– A plug-in power adapter (looks like a large phone charger)
– A 25-foot weatherproof cable
– Mounting hardware
How it works:
The adapter plugs into a standard wall outlet near your door (within 25 feet). The cable runs from the adapter to the Nest Hello, providing constant power.
Steps to Use the Plug-in Adapter:
- Choose an outlet: Find a GFCI-protected outlet near your front door. If the outlet is indoors, you’ll need to run the cable through a door or window (use a cable guard to protect it).
- Route the cable: Run the weatherproof cable from the outlet to the mounting location. Use clips or adhesive strips to secure it along the wall or door frame.
- Protect the cable: If running the cable outside, ensure it’s shielded from weather and foot traffic. Avoid sharp edges that could damage the wire.
- Plug in the adapter: Connect the adapter to the outlet and the cable to the Nest Hello.
Tip: If your outlet is far from the door, consider using a longer extension cord rated for outdoor use—but only if it’s safe and code-compliant.
Step 2: Prepare the Mounting Location
Once your power source is ready, it’s time to choose where to mount the Nest Hello. The ideal spot is at eye level (about 48–60 inches from the ground), facing the walkway or driveway.
Factors to Consider
- Visibility: The camera should have a clear view of visitors approaching your door.
- Wi-Fi signal: Ensure the location has strong Wi-Fi coverage. Weak signals can cause lag or disconnections.
- Weather protection: Avoid direct exposure to rain, snow, or extreme sun. A covered porch or overhang is ideal.
- Accessibility: Make sure you can reach the device for maintenance or cleaning.
Mark the Mounting Holes
- Hold the Nest Hello mounting plate against the wall at your desired height.
- Use a level to ensure it’s straight.
- Mark the screw holes with a pencil.
- Drill pilot holes if needed (especially for brick or concrete).
Tip: If you’re mounting on brick or stucco, use wall anchors to secure the screws.
Step 3: Connect the Wires (If Hardwired)
If you’re using a transformer and low-voltage wires, now’s the time to connect them to the Nest Hello.
Steps to Connect Wires
- Strip the wire ends: Use wire strippers to expose about 1/4 inch of copper on each wire.
- Open the Nest Hello: Remove the front cover by pressing the release button on the bottom.
- Locate the terminals: You’ll see two screw terminals labeled “Front” and “Transformer.”
- Connect the wires: Insert one wire into each terminal and tighten the screws. It doesn’t matter which wire goes where—Nest Hello is polarity-independent.
- Secure the wires: Use electrical tape to cover exposed connections and prevent shorts.
Warning: Do not connect the wires while the power is on. Always turn off the breaker before working with electrical connections.
Step 4: Mount the Nest Hello
With the wires connected (or the plug-in cable attached), it’s time to mount the device.
Steps to Mount
- Attach the mounting plate: Secure it to the wall using the provided screws and anchors.
- Connect the Nest Hello: Slide the device onto the plate until it clicks into place.
- Adjust the angle: Tilt the camera slightly downward for the best view of visitors’ faces.
- Secure the cover: Press the front cover back on until it snaps.
Tip: If you’re using the plug-in adapter, make sure the cable isn’t pinched or strained when mounting.
Step 5: Power On and Test
Now that everything is connected, it’s time to power up and test the system.
Steps to Test
- Turn on power: If using a transformer, flip the breaker back on. If using the plug-in adapter, ensure it’s plugged in.
- Wait for the light: The Nest Hello will show a pulsing yellow light, indicating it’s powering up.
- Check for video: Open the Nest app on your phone. You should see a live feed from the camera.
- Test audio: Speak into your phone and listen for sound from the doorbell. Tap the talk button to test two-way communication.
- Check motion detection: Walk in front of the camera to trigger a motion alert.
Troubleshooting Tip: If the device doesn’t power on, double-check your wiring, transformer voltage, or adapter connection.
Step 6: Set Up with the Nest App
The Nest app is your control center for the Nest Hello. It’s where you’ll configure settings, view recordings, and receive alerts.
Steps to Set Up
- Download the app: Available on iOS and Android. Search “Nest” in your app store.
