Red is used for displaying the maximum temperature,
yellow is used for displaying the medium temperature,
and blue and black are used for displaying the low
temperature, which is suitable for scenarios with
distinct colors of high and low temperature

Red heat
The main colors are red and black, and from the
minimum temperature to the maximum temperature,
the black, white and red transition mode is adopted,
which is suitable for scenarios focusing on the high
temperature state
Cold
blue
Blue is used to mark the colder regions, which is more
suitable for observing low-temperature target objects
By adjusting the color palette bar on the right side of the screen, the
temperature range can be adjusted to make the regions that need to be observed
more obvious

5.3.11 High Temperature Alarm
Click the switch icon of [High temperature Alarm], and a window for setting
the high temperature alarm threshold value pops up on the interface, as shown in
the figure below When the maximum temperature value in the screen is higher than
the alarm threshold value (in the regional temperature measurement mode, the
temperature in the region is taken as the benchmark, except point measurement),
the system will sound an alarm, and the video screen will flash a red alarm.
