The thermal Zenmuse XT camera was not extensively tested. For more information about the supported hardware: 203991609. However, flying a mission with the FLIR camera is expected to be possible with the Android or iOS app.
The drone will take pictures according to the flight plan but the video feed will not be working. It is required to capture the images in .tif format for a successful processing with Pix4D Desktop. Do not extract frames from a video recording. For more information: 208592186.

Regarding the app, there are several factors to consider before flying:
- Image format: Images are recorded in .jpeg format by default. This can be changed for the XT camera on Android but not iOS. The image format can be changed to .tif in the settings of DJI GO.
- Image resolution: For optimal processing, it is suggested to set the resolution (image size) of the pictures to 640x512 [pixel] and to use a focal length (aperture) of 7.5, 9, 13 or 19 mm. Use DJI GO to change the options. These characteristics correspond to camera models in the Pix4D desktop database.
- Image overlap: The overlap in the app is based on the 9-mm lens which has a specific field of view (FoV). The overlap needs to be adapted accordingly for other lenses. A longer focal length requires that you exaggerate mission's image overlap percentage to account for the camera's narrower FoV.
