Improving rearview camera at night
 

I have a Kenwood CMOS200 installed on my Z for rearview camera. It works great but at night the image is very washed out due to lack of rear view light. My Honda has an original OEM rearview camera installed and it does not suffer from the same problem. Does the rear fog light help with this issue? Is there another way to improve the rearview camera at night?
