Digital night vision is technically based on the IR CMOS board camera used in the build. If you are researching it ask your vendor what board camera they are using.
They may say a branded name but all CMOS cameras are made in China. Digital Crosshairs 1000 uses 1099 IR CMOS camera boards that are 1000 television lines in resolution. They also use an IR illuminator based on the Oslon Black 850nm IR emitter, the most powerfull in the industry. Technical facts like these you should ask of any vendor.
China does not make great innovative products but they do make quality component, like CMOS board cameras, batteries, and displays used by all U.S.A. manufacturers. Your Ford has an LCD made in China.
When looking at digital night vision think of it as the commodity it is becoming today. IR illuminator, CMOS board camera, mini LCD display resolution or in the case of Digital Crosshairs 1000 a 4.3″ rail mounted LCD display are the future of night vision technology for hunting.
A $4000 dollar night vision product and the $600 dollar Digital Crosshairs product should be judged based on components not brand names.
