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

Even Cat5 would be OK, since the higher speed and bandwith capabilities of Cat5e, Cat6 or Cat 7 are not required, but I would use at least Cat5e , which is very affordable these days.

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?
