I am not sure if it's everywhere in the world, but in Australia a "Doodle" can often be slang for a penis. With this in mind, I am not sure DoodleCam is a great name unless that's what you were going for.
I was kind of expecting your service to be like chatroulette which also could have been called DoodleCam.
In North America, "doodle" is what people do in their notebooks during boring meetings—draw, that is. So it may be a cultural thing. For their target audience, it's fine.
