I was givin these instruction from flirone support to reset the infrared camera
There is a pinhole reset button on the bottom of the FLIR ONE near the charging port. Please complete the following steps :
1. Power on FLIR ONE ie, move the shutter arm to the middle position
2. Press in and hold the reset button for 30 seconds
3. keep the FLIR ONE powered on for 24 hours to allow the battery to completely drain
4. Charge the FLIR ONE for 1-2 hours.
5. Connect the FLIR ONE to your iphone 5 to test function
