Thermal and visible-light operation
“Dual payload” thermal cameras are equipped with 2 cameras — a
thermal imaging (infrared) camera and a visible-light camera.
Thermal camera
— provides
night-time imagery, based
on temperature differences
between objects. Thermal
imaging produces a clear
image even in total darkness.
Visible-light camera
—
provides black and white (or
greyscale) imagery during the
day and in low-light conditions.
Helps to improve navigational
abilities in low-light conditions;
for example during twilight
hours when operating along
intercoastal waterways and
near harbor entrances.

The T470SC and

camera and continuous
zoom lens.
