the IP camera. You can configure audio for these devices:

Internal microphone—The IP camera includes an internal microphone that can capture audio at the 
camera location. This audio is sent to the PC that you use to view video from the IP camera. You 
can listen to the audio when viewing video in the Home window.

External microphone—You can connect an optional external microphone (available from 
third-parties) to the IP camera. This audio is sent to the PC that you use to view video from the IP 
camera. You can listen to the audio when viewing video in the Home window. Connecting an 
external microphone disables the internal microphone.

External speaker— You can connect an optional external speaker (available from third-parties) to 
the IP camera. This speaker plays audio that is captured by the microphone of the PC that you use

window is open.
