Any invited user with an owner or member account can use built-in two-way audio to talk to someone at home through the camera.
To activate two-way audio:
- Open the Home tab in the app
- Tap the 2-Way Talk microphone icon to start a conversation
- Tap the mic again to end the call
Lighthouse doesn't record audio, but two-way audio can be used to listen to what's going at home when you're not there.
