that’s called “exposure time”. turn the lights on in your room. that’ll make it better.

or increase the frame rate. that limits the exposure time as well.

you probably didn’t enable MJPG compression (it’s the FOURCC property). without it, frame rate naturally drops, which allows longer exposure times.
