Free Online Thermal Imaging Camera Videos & Training Courses

In this article, I have put together some free online thermal imaging camera training videos and courses. They'll help you get the most out of your thermal imaging camera. If you prefer in-person training, we also offer a half-day thermography course.

Key Thermal Imaging Concepts & Examples [ 25 Minutes ]

This video is a bit of sales-pitch from FLIR for their multi-day infrared training courses. Even so, you can glean some of the most critical thermal imaging concepts to be aware of.

Here are some key takeaway messages from the above training video:

  • The visual and thermal world can look very different. The visually-vivid photo in their lobby comes up blank on a thermal camera - except for a handprint where someone has recently touched the wall. The trainer actually forgets to mention this key point (and explain the handprint) in the video! 
  • Heat capacitance of an object (how it responds to and stores thermal energy) affects its thermal signature. 
  • The colour of an object does not necessarily affect things in the infrared spectrum. For example, when a flag is placed in sunlight, it does - because the colours absorb and re-radiate the solar radiation differently. The same flag indoors has no discernable difference between the colours.
  • Even ice and snow emit detectable thermal energy.
  • Materials with different moisture content radiate differently. 
  • Emissivity is a crucial concept in thermal imaging. Shiny objects are poor emitters of infrared energy. Be careful when measuring shiny objects! More on this below.
  • Infrared cameras do not see through physical objects. But they can help you see things otherwise not visible to the naked eye. For example, a thermal camera cannot see through a window. This is because glass is opaque to infrared radiation but transmits the visual spectrum.
  • Conversely, you can see through some things in infrared that you can't see through visually (like smoke).
  • Thermal resolution is a critical specification for thermal imaging cameras. The higher the resolution, the further you can see (all else being equal).
  • At about 9 minutes into the video, the trainer outlines a wide range of useful thermal imaging applications. These include: detecting electrical hot spots, inspecting motors, tank levels, values, belt drives, insulation, air conditioning vents, water leaks, manufacturing applications, and more.
  • From about 16 minutes onwards the video dials up the sales-pitch and includes a few more useful examples.

A Quick Summary of Thermal Emissivity [ 6 Minutes ]

As you may have noticed in the above video - emissivity is a critical concept. Emissivity describes the ability of an object to emit thermal radiation. It's a setting that you can manually adjust - even in our lower-cost thermal cameras like the FLIR One Pro.

To adjust emissivity settings, and correct for it, you need to know how it works. In this short video, you can see how to overcome accuracy issues when measuring shiny metal objects - or other reflective surfaces.

Now that you understand some of the basics of thermal imaging, it's worth delving into the specifics of your particular infrared camera.
