Nest Hello is a video doorbell system from Google that allows homeowners to see who is ringing their doorbell and view any packages left on the doorstep. It provides 24-hour streaming, 3 hours of snapshot history, and sound, motion, and person detection. Google also offers optional add-on services such as familiar face recognition and package tracking.

Nest Hello doorbell installation is a relatively straightforward procedure that most homeowners should be able to complete on their own. Below is a step-by-step guide on how to install a Google Nest doorbell that makes the process clear and easy to follow.

Gather Your Tools and Materials

To install your Nest Hello doorbell, you will need a Phillips-head screwdriver, a power drill, the right drill bit, a bubble level, wire strippers or cutters, a stepladder, a smartphone or tablet, and, of course, the doorbell itself.

Check Your Doorbell and Chime Compatibility and Voltage Requirements

Most of the time, you can replace your existing doorbell with a Nest Hello doorbell, but it is important to check the compatibility and voltage requirements before you begin.

First, remove the cover from your chime box. If you are not sure where yours is located, ring the doorbell, then follow the sound.

If you see two or more wires or wires and batteries inside your chime box, then your doorbell should be compatible with the Google Nest Hello doorbell.

If you see only batteries, then your doorbell is not compatible unless you buy the Indoor Power Adaptor, which allows you to use an indoor power outlet for the Nest Hello. You can also use the Indoor Power Adapter to install Nest Hello without an existing doorbell.

To check the voltage, you must first locate the transformer. You can find it by following the wires out of the chime box. Transformers are often located inside the doorbell chime box, in the attic, basement, crawl space, or near the circuit breaker or fuse box.

The voltage for your transformer should be etched or molded right on the box. The Nest Hello video doorbell requires between 16 and 84 volts. Since this is a wi-fi device, you’ll obviously need a wifi network with sufficient upload speed to stream the doorbell’s video to your devices.

Set Up the Nest App

Install the Nest App from Google Play or the Apple App Store, then sign in to the Nest App. Add a product by clicking on the + sign and scanning the QR code with your smartphone or tablet.

Install the Chime Connector

Wired doorbells require chime connectors to protect the chimes. Without the chime connector, the constant flow of current can damage your chime and cause it to buzz or chime at odd times. The Nest app will walk you through the steps of installing the chime connector.

There is no need for the chime connector if you are using the Indoor Power Adapter to install your Nest doorbell.

Turn Off the Power

Go to your circuit breaker or fuse box and shut off the power to your doorbell and chime.

Change the Chime Terminal

First, open the chime box. The cover may pop off or you may need to remove screws first. Inside, you will see terminals labeled FRONT for front door, BACK for back door, and TRANS for side door.

Change the Front Wire

Disconnect the front wire from the terminal, then straighten it and trim it until you can see a quarter inch of bare wire.

Open the chime connector by pinching its white plastic terminal. Inset the wire you just trimmed, then relax your pinch to close the terminal. Place the connector’s white wire into the front terminal of your chime.

Change the Trans Wire

Follow the same procedure using the gray wire on the chime connector to change the trans wire.

Attach the Chime Connector

Find a good location for the chime connector. If there is room, you can place it inside the chime box. If not, place it outside the box. Then put the chime box cover back on.

Remove the Old Doorbell

The old doorbell should easily come off by unscrewing the two screws. Then disconnect the wires and bend or tape them to prevent them from falling in the holes.

Install the Nest Hello Wall Plate

Place the wall plate so that the Nest logo is at the bottom. Pull the wires through the center hole so that the wires come through the bottom of the center hole. Then mark each screw hole with a pencil.

Use those marks as a guide to drill two 3/32-inch pilot holes. Then use the two screws that came with the Nest Hello doorbell to attach the wall plate. Use your bubble level to make sure it is straight.

Install the Nest Hello Doorbell

Connect the terminals on the Nest Hello to the wires. Point the wires down. If there is any excess wire, push it back into the hole.

Then slide the doorbell into the wall plate, making sure it clicks at the bottom. Use the wedge provided to change the angle of the camera.

Turn the Power Back On

Go to your circuit breaker or fuse box to turn the power back on. You should see a blue ring around the doorbell button when the power is on.

Connect the Nest Hello Doorbell to Your Wi-Fi

In the Nest App, choose the doorbell’s location, such as the front door or back door. Then select your Wi-Fi and type in your password.

Test the Doorbell

The Nest Hello doorbell should turn on quickly. The light ring should turn blue and you should hear a chime. You can also test the doorbell by manually ringing it.

If it does not turn on, go through the troubleshooting guide in the Nest app.
