Tested cameras in my back yard, and although there is a lot of light pollution in the suburbs, I test all cameras in the dark in the same conditions. Illumination distance on still images with the Spec Ops Elite HP4 is DRAMATICALLY better than the Dark Ops Pro XD. I would say 20-30 feet farther. Still some image blur with motion on the HP4, but not as bad as the Pro XD. Video on both units good, but HP4 double the clarity of Pro XD. The HP4 also has a night setting that will reduce motion blur, but it will also reduce illumination distance.
So far, very pleased with HP4.
