To see local warming and therefore weak points in our environment has been always been the most fascinating point within modern thermal imaging technology. Based on more efficient manufacturing technologies for the IR optical image sensors, those cameras resulted in a drastic improvement of their price-performance ratio. The devices got smaller, more robust and more economic in their power consumption. For some time now measuring thermographic systems are available, which are - similar to a traditional webcam - controlled and powered only by an USB port.
