Problem Description

When using two-way audio on your Nest Cam Indoor Wired, there is an annoying echo or feedback loop. You hear your own voice repeated back, or the person at the camera hears themselves with a delay. This makes conversations difficult and the audio quality unusable for meaningful communication.

Symptoms

  • Your voice echoes back during two-way talk
  • Person at camera hears delayed feedback
  • Audio becomes screechy or loops
  • Echo worse when phone volume is high
  • Two-way audio worked before but now has echo
  • Echo only happens with certain phones

Recognize these? Here's what usually causes it.

Common Causes

  • Phone speaker audio picked up by phone mic
  • Camera speaker audio picked up by camera mic
  • Processing delay creating audible loop
  • Phone case covering microphone
  • Camera placed in acoustically reflective space
  • Bluetooth audio device adding delay

Most fixes happen in the first 3 steps.

Warning

If echo only started recently and no settings changed, check if the camera has a pending firmware update. Some firmware versions have had audio processing bugs that are fixed in updates.

Step-by-Step Solution

1

Use Headphones or Earbuds

The most effective fix is using headphones or earbuds when initiating two-way audio. This prevents your phone speaker output from being picked up by your phone microphone and transmitted back to the camera. Any wired or wireless earbuds with a microphone will work.

2

Lower Phone Speaker Volume

High speaker volume increases the chance of audio being picked up by your microphone. Before starting two-way audio, lower your phone volume to 30-40%. You can still hear clearly but there is less audio leaking to create feedback loops.

3

Reposition the Camera

If the camera is in a small room or near hard reflective surfaces like windows or tiles, audio bounces back to the camera microphone. Move the camera to a location with more soft furnishing like carpet, curtains, or upholstered furniture that absorbs sound rather than reflecting it.

4

Disconnect Bluetooth Audio

If your phone is connected to Bluetooth speakers or headphones, there can be processing delay that creates echo. Disconnect Bluetooth audio devices before using two-way talk. Use the phone built-in speaker and microphone for lowest latency.

5

Update Google Home App

Echo cancellation algorithms are improved in app updates. Ensure your Google Home app is fully updated to the latest version. Check your app store for updates. After updating, test two-way audio again as improvements may resolve the issue.

Quick Solutions

Use headphones or earbuds when using two-way
Lower phone speaker volume significantly
Move camera away from reflective surfaces
Disable Bluetooth and use phone speaker directly
Position camera in acoustically dampened area
Check for app updates with echo cancellation fixes

Still having issues? This is usually the deeper cause below.

If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.

Pro Tip

Test two-way audio in the Google Home app with only one person at the camera. Background conversations at the camera location can create additional audio feedback that complicates the issue.

Real-World Insight

This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.

What Usually Goes Wrong
  • Phone speaker audio picked up by phone mic
  • Camera speaker audio picked up by camera mic
  • Processing delay creating audible loop
  • Phone case covering microphone
  • Camera placed in acoustically reflective space
