Spotlight Camera Night Vision With White Gutters

I recently set up some Spotlight cameras with third party gutter mounts. A couple of my cameras work great this way, but any that have a view of the white gutters themselves only shot the gutters and black screen at night. Is there any way to adjust these cameras so that the cameras work better at night? I could point them further away from the gutters, but I would prefer not to have the camera pointed at my neighbor's house (I certainly would not want to have my neighbor's cameras visibly pointed at my house).
