Don’t worry, here are some methods that may help you:
①If the device has not been used for a long time, please wait for 15 to 20 minutes after it is on to ensure the normal use of the device.
②If the object releases heat in a relative fixed position for a long while, heat in its position might still be remained after the objects gone, and ghosting will be seen through infrared thermal imagers. Please be noted that it is a normal phenomenon. You can verify it through changing another time or scene to take photos.
③Reboot the device to check whether ghosting issues can be optimized or not.
④Upgrade system version to the latest.
⑤Calibrating the device manually. Calibration method may vary from different models, please contact our technology personnel for more details.
