Lines can be anything from a d.c supply fault to ground loop issues, a picture would help for a more accurate diagnosis.

i used to get the lines on one of my old cameras, and it turned out to be that the camera was a CMOS camera which is the lowest quality. and CCD is the best

but then again if you are using a CCD camera its possible like what colin said about the power, also possible that it might not be gettin enough power
