19. INFRARED CAMERA BEHAVIOR
19 Infrared Camera Behavior
19.1 Infrared Camera Warm‐Up
Modern infrared cameras based on a microbolometer array need to internally warm up to their working tem‐
perature before the measured values stabilize. The sensor begins to automacally warm up aer the user turns
the camera on. The infrared camera is usually up to ideal internal temperature in about 15 minutes.
During the warm‐up process the accuracy of the measured temperature data is lower and various defects can
appear in the thermal image. Therefore, we recommend to let the infrared camera warm up before capturing
crical data.
19.2 Non‐Uniformity Correcon (NUC)
Infrared cameras need to be periodically calibrated in order to get reasonable measurement accuracy. This pro‐
cess is called Non‐uniformity correcon (NUC) or shuer calibraon. WIRIS Pro is equipped with an internal,
automated shuer which can be triggered manually but also engages automacally in a set interval.
Note: Time unl the next automac calibraon is shown in STATUS BAR. The downside of NUC is that
the stream of thermal camera image gets briey interrupted while the NUC is performed, so while more
frequent NUC means higher quality data, user has to be aware of the frames that will be lost with each
NUC.
Note: Whenever the device detects too rapid shis in internal temperature, the NUC mer indicator
(present in Inspecon layout Status Bar and oponally in Inspecon Panel in other layouts) will turn red.
This means the accuracy of thermal data may be lower but no funconality is impaired.
Note: Even aer NUC is performed, temperature non‐uniformity can, depending on the environmental
circumstances, sll reach up to 4
