Angle your Nest Doorbell with a wedge

The Nest Doorbell (wired, 3rd gen) comes with a wedge that you can use to adjust its camera angle if it’s located in a corner. This wedge can angle your doorbell horizontally up to 20°.

Tools

• #2 Phillips screwdriver

App and internet requirements

• The latest version of the app

1. Switch the power off for your doorbell and chime at your home’s breaker or fuse box. This will protect you and your equipment during installation.
2. Try to ring your doorbell to confirm that you’ve flipped the right switch to turn the power off. If needed, you can switch off the main power at the breaker box instead.

Remove your old doorbell and disconnect the wires. You’ll probably need a screwdriver for this step.

Tip: As you remove your old doorbell, bend or tape the doorbell wires so that they don’t slip back into the wall.

To remove your old hardware, go to Uninstall wired Nest doorbells and chime connector.

During setup, the app lets you connect your doorbell to Wi-Fi, personalize settings, check the video quality, and more.

If you experience any issues, here are some quick tips.

Connection issues

If you can’t find your Wi-Fi network, or if your doorbell has trouble connecting to the Wi-Fi:

• Wait a few minutes, then try to connect your doorbell again.
• If possible, move your doorbell and router closer to each other to improve the signal.
• Reduce wireless interference.
• Try to restart your router.
• If you have a hidden Wi-Fi network, you’ll need to type in the network name (SSID) manually in the Google Home app.

Power issues

Signs that your doorbell isn’t getting enough power include the following:

• Your doorbell won’t turn on.
• You get a message or status in the app that tells you there isn’t enough power.
• Your doorbell has Wi-Fi connection issues and lower video quality.

To try to fix the issue, check that the power is on for your doorbell system and that the wires are connected properly to it.

Important: Some doorbell systems have complex wiring that might not have diagrams in the app. For additional help, check our wiring diagrams.

Video quality issues

If your doorbell has video delays or lag, the Wi-Fi connection may be weak. It could also be a sign that your doorbell isn’t getting enough power. Try the following to fix the issue:

• If possible, move your doorbell and router closer to each other to improve the signal.
• Reduce wireless interference.
• Check that the wires are connected properly to your doorbell.

If your doorbell’s video is distorted, here are a few things you can do:

• Dust off the camera lens.
• Ensure your doorbell is shaded and protected from extreme weather conditions. While Nest doorbells are built to work outside of your home, extreme hot or cold temperatures can affect things like the video quality.

For more tips, go to Troubleshoot Nest camera video distortion.

Important: Don’t let the wire connectors touch the backplate. This can cause an electrical short and damage the doorbell. Make sure that they only touch the screws. Tighten the screws to secure the connectors.

1. Before you connect the wires make sure they are clean.
2. Connect the power wires to the wire connectors.
   • You can connect the wires to any connector.
   • Press down on the release tabs to insert the wires into the connectors.
   • If you see exposed wire, remove the connectors and trim any excess wire.
3. Make sure the wires point down, not up, so the extra wire can be tucked back into the wall.
