The toggle switches on the back will turn features on and off...just test cameras during the day when it is really bright, switch toggles one by one off, then back on if it doesn't help. One of those switches will resolve your problem. Otherwise, the lens you have on there may have an aperture adjustment, just turn it...similar to the focus dial, and you will see the picture get darker or lighter depending on your application of the camera. An auto Iris camera eliminates the need for this dial.
