Contemplating doing a live vid feed while you are doing a live broadcast? It's intriguing and it can give your audience/listeners an inside look at what you are doing and why you love doing it.
That being said, you have to remember that you can use either the cam built into your pc (most have one now) or a little usb pluggable vid cam.
I have one similar to this:
It has some nice features, and even though it's 720 dpi, it has the auto focus, which comes in handy. When you are broadcasting and looking at the cam, you dont always stay in one position, twisting, turning, gesturing....it's a good feeling knowing that what you are sending out is pretty smooth, and Logitech is a top brand.
There are other types that are 1080 dpi, such as this one, and i have something similar as well, plus, if you want, use a little tripod like you see below, if you dont want to worry about having to clip your cam. The tripod setup allows you to move the cam around and find just the right spot to give your listening audience, your 'best side'
