TiR-Mode
TiR-Mode (thermal sensitivity) expresses the ability of an infrared camera to
display a very good image even if the thermal contrast in a scene is low. A
camera with good sensitivity can distinguish objects in a scene that have very
little temperature difference between them.
Sensitivity is most often measured by a parameter called Noise Equivalent
Temperature Difference or NETD. NETD is defined as the amount of infrared
radiation required to produce an output signal equal to the system’s noise. The
noise rating of the system should be as low as possible.

When TiR-Mode is turned on, images are enhanced with the improvement to
the image clarity of live scan targets. This mode is used for building envelope
applications such as roofing, restoration, and remediation. Response times in
this mode increase (slower refresh rate) and the maximum temperature range
is lower.
Note
When you scan with the TiR-Mode on, the Imager displays a slight
blurring effect. For best image results, hold the camera steady. Image
enhancement cannot be applied to images after they are taken.
