ffmpeg IP Camera DVR recording

If you have home server and want to record streams from your IP camera you can use siple script like this:

while true; do
    ffmpeg -i "rtsp://<192 .cam.ip="">:554/user=admin&password=&channel=0&stream=0.sdp?Real_stream" -acodec copy -vcodec copy -fs 20000000 "/srv/ftp/cam1/vid `date`.mov" | true ;
done


Option -fs 20000000  limits file sizes to ~20MB

CPU usage is very low. Even raspberry pi should be able to save your data from multiple cameras.

NOTE: deleting old files is not implemented.
