Hi Kientrung,
- In case you want to connect to camera via http (snapshot JPEG images or MJPEG streams), see my explanation here.
- For RTSP streams we had recently an interesting discussion, and the result was that you can have multiple options (ffmpeg, avconv, vlc media player, motion software). In case you are interested in the ffmpeg solution, see my post here.
- In case you want to store video and review the history, you will need to store the camera images somewhere from your flow (again with ffmpeg, motion, ...) into a directory. Afterwards you have to show somehow the directory listing into you dashboard. That is on my large todo list, but I have not done something like that yet ...
