I see Yuneec has just announced a dual purpose camera:
With a three-axis gimbal and dual thermal imaging and low-light cameras, the E10T will be available later this year in four lens configurations and two resolution options: 320- by 256-pixel or 640- by 512-pixel. The 320-pixel thermal resolution will start at $4,999, while the 640-pixel thermal resolution will start at $7,999.
