Technical Parameter Analysis


The resolution of a thermal imaging camera refers to its ability to differentiate the smallest temperature changes, typically measured in mK. A higher resolution enables the camera to capture finer temperature differences, thus providing clearer images. Therefore, resolution is an important consideration when selecting thermal imaging equipment.


The sensitivity of a thermal imaging camera indicates the smallest temperature difference it can detect, usually measured in mK. A higher sensitivity allows the camera to detect smaller temperature variations. For applications requiring precise temperature measurements, high sensitivity is crucial.

Temperature Range

The temperature range of a thermal imaging camera refers to the range of temperatures it can detect. Different applications may require different temperature ranges. For example, some industrial applications may require monitoring at extremely high or low temperatures, while general security applications may only need monitoring within normal temperature ranges.
