The ThermoVision
®
Mariner is easy to use, but you should take a moment
to carefully read this section so you fully understand what you are seeing
on your display. While the imagery you will see on the monitor may look
like black and white daylight video, it isn’t! A few tips on how to interpret
some of the imagery will help you to make the most of your system.
Turn on the camera using the on/off switch on the JCU. The joystick
controls the pan and tilt features of the camera. Controlling the camera’s
direction becomes intuitive after a few minutes of experimenting. The
camera automatically adjusts to changing scene conditions so no
additional camera control is necessary.
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 differences in the “picture quality”; this is normal. The camera
senses small “differences” in apparent radiation from the objects in view,
and displays them as either white (or lighter shades of gray) for warmer
objects, and black (or darker shades of gray) for colder objects. This is why
you will see areas of other vessels under way such as exhaust stacks or
outboard engines that appear white, while the rest of the vessel may
appear dark (or cool). Scenes with familiar objects will be easy to interpret
with some experience. The camera automatically optimizes the image to
provide you with the best contrast in most conditions.
