What is night vision?

“Night Vision” is the ability to “see in the dark…”

Night Vision refers specifically to devices that can see low level light, such as light waves that appear under the visible spectrum (infrared light)…

Thermal refers specifically to devices that can see differences in the temperature (infrared radiation)…

That being said, you have two completely different markets for “night vision” devices. You have specifically, “night vision” and you have, “thermal”…
