I faced a similar problem recently, where the IP cam I had was streaming video through the internet and it was Chinese ofcourse. But I found a much simpler solution to avoid it. The camera had rstp support and internet forums have already guessed the rstp url so I used that to hook it upto my surveillance system. Regarding avoiding transmission to internet, I just disabled internet access to that device and boom it became offline camera.

This is the way. All my cameras are "offline", serving RTSP streams and snapshots on my local network.
