Operation Tips
As you experiment with the M-Series, you will see the world in a different
light. Consider every object you view in terms of how it will look “thermally”
as opposed to how it looks to your eye. Right after sunset, objects warmed
by the sun will appear warmest. Early in the morning, many of these objects
will appear cooler than their surroundings, so be sure to look for subtle
ball-down differences in the scene, as opposed to just hot targets.
Originally developed for the military, thermal imaging cameras are now
deployed in numerous commercial applications where it is impractical or too
expensive to use active illumination (lights). They are perfect for a wide vari-
ety of applications in addition to maritime, including transportation, security,
fire fighting, and medical applications. The cameras often provide improved
daytime viewing in environments where traditional video camera perfor-
mance suffers, such as in shadows or backlit scenes.
The M-Series camera is a state-of-the-art thermal imaging system that will
provide you with excellent night visibility and situational awareness, without
any form of natural or artificial illumination. The system is easy to use, but
you should take a moment to understand how to interpret what you are see-
ing on your display and how to use the controls.
While the imagery you will see on the monitor may at first look similar to
ordinary black and white daylight video, as you get familiar with the camera
you will appreciate the characteristics that make thermal imaging distinct. A
few tips on how to interpret some of the imagery will help you to make the
most of your system.
The thermal imager inside the camera does not sense light like conventional
cameras; it senses heat or temperature differences. As you experiment
with the system during daylight and nighttime operation, you will notice dif-
ferences in the picture quality; this is normal. The camera senses small "dif-
ferences" in apparent radiation from the objects in view, and, in white hot
mode, displays them as either white (or lighter shades of grey) for warmer
objects, and black (or darker shades of grey) for colder objects.
Your thermal imaging camera relies on the fact that all objects, even very
cold objects like ice, emit thermal energy in the portion of the infrared spec-
trum that this camera can "see", the long wave infrared (LWIR). Therefore,
unlike an illuminated infrared camera, a thermal imaging camera does not
need an additional active illumination source and images based on directly
radiated rather than reflected energy.
This is why you will see hot objects such as parts on an outboard motor that
appear white (or black, or red depending on the video image mode
selected), while the puddles of water and other cold objects appear dark (or
cool). Scenes with familiar objects will be easy to interpret with some experi-
