So again - do you want users to actually connect to your camera IP -- or to some other IP for the video that is not using your bandwidth the camera is connected too? In the dropcam, your video is sent to their servers and viewers would be pulling bandwidth from dropcam. And camera only has to send bandwidth for 1 feed of the video.
Its very easy to just have your camera feed imbedded on some website where the video is coming from your connection.. But this is going to be hard to scale, might be fine if couple of users.. But going to be an issue if you have lots of concurrent watchers.
If you want to have users that are getting your feed from some other server that has lots more bandwidth - good luck finding this for FREE that is not ad supported.
You could look into say something like
