ICE
TM
– Intelligent Contrast Enhancement
ICE
TM
* (Intelligent Contrast Enhancement) is a patented innovation from ISG INFRASYS. This
technology operates to automatically enhance background contrast when viewing extremely hot
objects. This improves visibility for the user as hot objects and cooler surroundings are clearly
visible simultaneously. The extra information is vital when viewing extreme temperatures in
Thousand-Plus Mode and increases the effectiveness of firefighting, whilst enhancing safety for
the firefighter.
The adjacent image captured in Thousand-Plus
Mode illustrates how ICE
TM
*
improves visibility in
practice –
1)
The detail in the fire is clearly displayed
whilst;
2)
The background is maintained in high
contrast.

Sensitivity Modes
The ICE
TM
system thermal imager incorporates two distinct sensitivity modes and selects the
appropriate mode automatically by analysing the thermal characteristics of the scene.
Normal Mode
‘Normal Mode’ is automatically selected when viewing
low to medium ambient temperature scenes and/or
when there is little burning material in the scene.
In this mode the thermal imager’s sensitivity is
optimised to maximise the clarity of the lower-
temperature parts of the scene, enabling crystal-clear
imaging of the ambient scene as well as displaying
small, localised hotspots up to 500
o
C without
saturation.
Thousand-Plus Mode
‘Thousand-Plus Mode’ is automatically selected when
viewing extreme heat conditions, for example, in
flash over situations or other extreme emergency
situations where safety could be compromised.
In this mode the dynamic range is set to maximum
to provide clear imaging of scene temperatures in
excess of 1000
°
C without saturation, designed to
allow easy analysis of structures and burning
materials while retaining excellent visibility of low-
