Rear Camera Issues

For those in snowy/rainy parts of the world, how are you finding the rear camera? I am in Chicago and if it rains or snows, rear cam becomes useless with dirt and water. Upon further inspection, it appears that the camera is too close to the edge of trim and easily susceptible to getting wet and dirty.

I am not expecting like VW flip cameras but could they have mounted further in under the trim?

Thoughts?

Thanks
