...Google. Has anyone tried it? It's insanely fun. If you you type in certain code in the Google search bar, you can get tons of different live security cameras. A lot of which you can zoom, pan, switch positions, etc. And it's totally real. Typing " inurl:view/view.shtml" will get you some, and there's tons more. Just Google search one.
It's some German dude who works at his computer a lot. If you mess around with the camera ((Continually putting it in different positions), he'll go up to the camera and start talking to you. I don't think it's working right now. He probably shut it off because I was messing with him just a few minutes ago. Anyway, find a good one and supply a link to the camera.
