Kristina,
You can do all of the above. You can choose your audio source on the Home tab within Instant Video Presenter.
1. Webcam:
There is a microphone on the webcam which you can use. Yes, the quality can vary greatly depending on the room you are in.
2. Microphone on a camera: If you have a different camera you can use the microphone on it or add a microphone to the camera. Make the selection in the home tab for the different audio source
3. Microphone direct to the computer: This would be my reccommendation. Most computers have an audio card with three inputs on them. Mic, line, and headphones. You would plug in your microphone to the Mic input (usually has a microphone icon next to it). Then select correct option on home tab.
If you use a webcam and microphone hooked to the computer (which is what we do) just select the webcam as your camera source and the new mic as your audio source on home tab. Make sure the microphone is plugged in (and turned on if needed) before you open Instant Video Presenter so that the program recognizes it.
