ffmpeg stream and save video from Dahua 4300s IP Camera

Use ffmpeg to stream video from a dahua 4300s to a file or files

You can use ffmpeg to directly pull frames off of a dahua 4300s at full resolution. May be a good alternative to pricey dvrs which likely cannot record at full resolution, may not work with the camera, or are prohibitevly expensive

Simple Stream to file

Simple stream to file. Full resolution

ffmpeg -loglevel debug -rtsp_transport tcp -i "rtsp://admin:admin@198.175.207.61:554/live" \

-c copy -map 0 foo.mp4
