Welcome to the Cow Audio Forum Jim,
Does this camera have XLR inputs? “When hooked up to the camera”, when what is hooked up to the camera?
If the camera has XLR inputs, I don’t think it’s bias voltage. I’ve only seen bias voltage on 1/8″ audio inputs. I have seen phantom power cause problems when it’s on at the camera and the camera is being fed by a mixer instead of a mic requiring phantom power.
If you’re trying to feed the camera from a mixer, be sure the camera phantom supply is off.
