Night vision...

There is this website for night vision equipments, and I am curious what I can find, to maybe give to my relatives that would be interested in one or two "night vision" items. Because it wasn't that long ago that my beloved uncle was brutally murdered, so I think it would be sensible if my people will have one of these items for protection against those bad guys that surrounds our place. I want to make sure my family is well protected and will have a fighting chance when it comes to defending themselves. My uncles sometimes will have to walk a long way home, so perhaps, they need some of those nigh vision googles.
