One of my cameras seems very dull and not light enough in the video, I have the camera settings at max, is there anything else I can do to increase the brightness?  The settings are ma at +2 !!

Has the plastic film over the lens been removed? If you move the camera to a different location, does it look better? It's possible that light is directly hitting the lens, washing out the image.
