When it comes to making the invisible visible, thermal imaging devices are the best choice. Using a conventional night vision device (residual light amplifier) in darkness is only as effective as turning on a weak flashlight.
This makes it practically impossible to find a camouflaged suspect leaning against a tree, a missing child lying on the forest floor or an intruder hiding in a bush. However, all of these people will stand out clearly from their surroundings on the screen of a thermal imaging camera – not just at night, but in daylight as well as in fog or smoke-filled environments.
