Ty,
I believe you’re accessing just the camera controls remotely via the camcorder’s IP address through internet. In this camera monitoring and control operation there is no audio passing through. However, when the camcorder is linked to an IP address, the video stream will contain audio as being captured/recorded.
Another way to look at this is that someone can control the camcorder separately via an internet connection (like a producer located in another part of the country) while it is streaming.
I hope this helps. Please contact our help dest at 800.582.5825 if you need additional assistance.
Cordially,
