Color alarms

19.2.1

General

By using color alarms (isotherms), anomalies can easily be discovered in an infrared im-
age. The isotherm command applies a contrasting color to all pixels with a temperature
above, below, or between the set temperature levels. The camera also features isotherm
types that are specific to the building trade: condensation and insulation alarms.

You can make the camera trigger the following types of color alarms:

Above alarm

: This will apply a contrasting color to all pixels with a temperature above

the specified temperature level.

Below alarm

: This will apply a contrasting color to all pixels with a temperature below

the specified temperature level.

Interval alarm

: This will apply a contrasting color to all pixels with a temperature be-

tween two specified temperature levels.

Condensation alarm

: Triggers when the camera detects a surface where the relative

humidity exceeds a preset value.

Insulation alarm

: Triggers when there is an insulation deficiency in a wall.
