* Shutter correction function can correct the non-uniformity of infrared images and the accuracy of temperature measurement; the device needs 5-10min to stabilize during the boot process; the device defaults to 3 times of start-up shutter correction, after that, it is not corrected by default, and the back end can periodically call the shutter correction, correct the image and temperature data.
