It seems these helmet cams have trouble on cloudy days. Adjusting the light from looking at sky to ground. They seem to make a better vid on sunny days.

boreality,
That's true of any camera. Manual control of exposure is a must for difficult lighting situations.
For instance, whether it's sunny or overcast, if the subject is in shadow, there will be too much dynamic range for the bright sky and the subject to both be properly lit. But in overcast conditions, a digital sensor, especially simpler ones such as would be in a helmet cam, really stumble.
A quick way to fool the sensor is to aim the camera at a darker section of the scene, then quickly move back to the subject. The lag in the time it takes the sensor to adjust to the overall brightness of the scene can give a few seconds of better exposure of the desired subject.
