Will the Bunker Hill security camera's get sun spots or will they burn out.

Will Bunker Hill security camera's get sun spots or will they burn out if they are positioned in a way that the evening sun is shinning directly at them. If so can you buy a special lens for them to keep this from happening or a housing to go around the camera to keep them from burning out. I know that camera's from days gone by would burn out. I also know a gentleman that has a bunker hill system with a camera that looks to the west that appears to be burnt out. I am in Tucson, Arizona we have a little more heat than in most parts of the country. I sort of need to get this system up as quickly as I can so a quick response would be appreciated. Also do you make a wide angle camera or do you have a wide angle lens that can be adapted to your camera.
Thank You Very Much
