Can I use a separate audio device to record audio while recording video from my USB camera?

Is it possible to use My Screen Recorder Pro to record only the fixed region on screen every time I start recording?

I am using Auto FTP Manager for transferring files from multiple FTP servers to my PC. I have many profiles and I would like to save a backup of all my profiles in case of any problems in the future.

I am using My Screen Recorder. I want it to record only when there is movement on screen, otherwise don’t record the screen. Is it possible?
