Helped invent a thermal camera that works via mobile device.

Jeff Frank’s efforts in bringing Flir One to the market have revolutionized the way builders track performance and structural issues on the jobsite. A simple phone attachment, Flir One uses two cameras to provide physical detail to raw thermal imaging, allowing building pros to literally see inside walls.

The Flir One easily spots holes in insulation, leaks in the building envelope, plumbing blockages, or overloaded circuits. It’s affordable and easy to use for even the most tech-phobic builder.
