How good is the WDR in D800 Cameras?

I will be installing cameras facing a glass storefront (from the inside out). I am wondering if I will be able to see people's faces clearly or will the sunlight coming through the glass blind the cameras, specifically the B800/D800 cameras?

I am afraid the glass will have some effects on the image. Also, it is suggested to install the camera somewhere avoids glare.

Unfortunately, relocation of the camera is not an option. I need to be able to see and identify who comes into my restaurant!
