Six months ago, I was tasked with equipping our entire thermal inspection team with new cameras. The budget was significant, but so were the stakes – these tools would determine our competitive advantage for years to come. After testing 23 different models from 8 major manufacturers, conducting over 200 hours of field comparisons, and analyzing thousands of thermal images, I discovered that the thermal camera comparison landscape is far more complex than marketing materials suggest.

The results of this comprehensive thermal imaging comparison analysis fundamentally changed how I evaluate thermal imaging technology – and probably saved my organization over $50,000 in suboptimal equipment purchases.
