Image settings
On this page, you can tune the White balance and Image adjustment.
Image Adjustment
■ Brightness: Adjust the image brightness level, which ranges from
0% to 100%
. For hotter
scenes during the day, higher brightness brings up more details; while in the colder night, lower
brightness is suitable for details in an environment with a lower temperature.
■ Contrast: Adjust the image contrast level, which ranges from 0% to 100%. A higher contrast is
needed when temperature difference is little.
■ Sharpness:
Adjust the image sharpness level, which ranges from
0% to 100%
.
Note that the thermal performance can vary throughout a day. Objects like concrete walls or
pavements can preserve energy from the sun even hours after sunset. Metals, e.g., metal roof,
however, can dissipate heat and cool down more quickly. The appearances of different materials
will change accordingly throughout the day.
