This is a very brief tutorial how to get a stream of the Raspberry Pi camera into a browser. The original article can be found here.
I was searching a lot how to stream directly from the camera to the network, yet I did not find a solution. So what we are doing here is using the timelaps feature from raspistill combined with MJPG-Streamer. In the end you will be able to see the stream in a webbrowser or in VLC Media Player.
