Built-in microphone and speaker provide two-way audio function

I cannot find any instructions for the “Built-in microphone and speaker provide two-way audio function” feature for the Vista Cam HD.
Any suggestions?
Thanks

Pretty sure that is not supported in VERA. If you connect directly to the camera, you can pull in audio from the mic. I don’t know about the speaker…

Thank you for that information. I bought it from Vera and those features are listed by Vera on the website. Hopefully, the feature will be added in the future.
