Noisy image
Possible causes
Poor quality or faulty cabling. • Ensure cable runs are no longer than they need to be.
Cable is picking up
electromagnetic interference
(EMI) from another device.
Image too dark or too light
Possible causes
Brightness set too low.
The contrast and / or
brightness settings in the
Camera app are set too low.
The Scene Mode is not
appropriate for the current
conditions.
Image freezes momentarily
Possible causes
FFC (Flat Field Correction).
Image is inverted (upside down or mirror image)
Possible causes
Vertical or Horizontal flip
control incorrectly set
Troubleshooting
Possible solutions
• Use only high quality shielded cable suitable for the marine
environment.
• Ensure you are using a high quality shielded cable.
• Ensure proper cable separation, for example do not run data and
power cables in close proximity with each other.
• In certain conditions it may be necessary to fit suppression
ferrites to cabling to eliminate interference.
Possible solutions
Check MFD brightness and adjust if necessary.
Check Camera brightness and contrast, adjust if necessary.
When viewing a thermal camera feed, a particular environment may
benefit from using a different Scene Mode setting. For example, a
very cold background (such as the sky) could cause the camera to
use a wider temperature range than appropriate. Adjust the Scene
as appropriate.
Possible solutions
A Thermal camera's image will pause momentarily on a periodic
basis during the Flat Field Correction (FFC) cycle. Just prior to the
FFC, a small green square may appear in the upper left corner of
the screen.
Possible solutions
Check the image flip controls to ensure they are set correctly for
your installation.
