The TG165 has higher resolution, but the VT04 has the nice feature to take pictures automatically every 10 minutes when a threshold temperature is exceeded. Unfortunately the IS2 file format of the VT04 is not published and Fluke doesn't want to publish it
Using other thermal cameras connected to device with OpenCV like some Nvidia tablets or regular PC, one can easy write such application and no thanks to
Fluke for their closed formats
Will see how
Seek Thermal with USB OTG will behave when they publish developers tools.
There is a question about supported temperatures ranges in thermal devices, but if one can in realtime get thermal image on device with OpenCV one can do everything with such thermal images-thermal image specs are then limits only.
I hope
Seek Thermal team is smart and they know that they do not have to fight with
Flir's MSX patents, while when they provide thermal camera plugable to decent computing power those devices can download any even Open Source software which will give users unlimited options to convert those thermal image and even make fusion with visual light like in
Flir's MSX .
Those Fluke and Flir closed software will no longer be needed as well as their thermal cameras in many practical use cases of IR analysis
