这是相机在执行非均匀性校正（NUC），消除相机自身发出的热信号，开机后较频繁，几分钟后明显减少。
中文概述：该声响来自热像仪的非均匀性校正（NUC），属正常现象。
What is the 'click' sound I occasionally hear from the camera? The camera is conducting a non-uniformity calibration (NUC). The process is eliminating the thermal signal emitted by the camera itself. The phenomenon occurs more frequently right after the camera is turned on and will become much less frequent after a few minutes.
