We have covered a bunch of awesome thermal imaging cameras here in the past. The FLIR Vue is a thermal imager for your drone. It is light enough not to impact your unmanned aircraft in a negative way. Just plug in a GoPro-compatible cable into the 10-pin mini-USB connector to get started. You can mount the camera in a wide variety of ways.
FLIR Vue is designed to offer easy integration with your drone. It could come handy for search & rescue, fire fighting, roof inspections, and other challenging projects. You can find this product on FLIR.com.
