What is an infrared camera (at least in the terms of an energy audit)? The infrared camera is one of the indispensable tools for an energy auditor. It scans the infrared light spectrum, responding to changes in heat. My Flir b50 Infrared Camera helps me accurately assess differences in temperature to evaluate insulation, air leakage and locate thermal, structural and moisture issues.

What Is An Infrared Camera – The Features

My camera features (and I totally didn’t pull this right off FLIR’s website):

  • IR camera with 140 x 140 pixels resolution
  • Digital camera of 1536 x 1536 pixels

This is a sample photo taken with an infrared camera. The hotter areas are colored white to red, while the cooler areas are blue. At a glance, I can tell where the heat is escaping in your home.
Most homeowners think infrared cameras are only useful for evaluating insulation. However the temperature scale shown by the camera is incredibly versatile. The infrared camera can assess air leaks, water leaks, mold and mildew spread, building structure and electrical fuse temperature.

My infrared camera is an invaluable tool for at a glance information on a huge variety of common household issues.
