I am using a 9Vdc composite video camera with mike in my car. I was
wondering if a DC converter to 9v like the Radio Shack version is safe to
operate the camera from the car battery.

Also, I need to attenuate the audio. The motor volume overwhelms the mike
and distorts the sound. The sound and video outputs are going into a VCR. Is
there a way I can attenuate the sound before it gets to the VCR?

Thanks

John
