The Network Camera supports two way audio communication so that operators can transmit and 
receive audio simultaneously. By using the Network Camera’s built-in or external microphone and 
an external speaker, you can communicate with people around the Network Camera.
Note that as JPEG only transmits a series of JPEG images to the client, to enable the two-way 
audio function, make sure the video mode is set to "H.264" on the Media > Video > Stream settings 
page and the media option is set to “Media > Video > Stream settings” on the Client Settings page. 
Please refer to Client Settings on page 35 and Stream settings on page 68.
