What Is Thermal Imaging?
Thermal imaging cameras (also known as infrared cameras) detect the heat that is produced by an object or person.
Thermal imaging cameras have lenses that focus on waves from the infrared energy present in all objects. Thousands of sensors then convert that infrared energy into electrical signals which creates a “thermal profile” video image.
Thermal Imaging For Building Inspections
Infrared cameras are very useful for building and pest inspections & pre-purchase inspections because they can help identify areas of poor or inadequate insulation, moisture leakage and termite infestations in a non-invasive way.
While thermal imaging is extremely useful (especially for trained inspectors) it is not a magical device that can “see through” walls and it certainly does not guarantee that you will find hidden defects or termite activity.
The detection of defects or termite activity using thermal imaging is not a simple process and it requires knowledge, skill, experience and specialist training.
The process takes many factors into account such as:
- the climate
- the structure’s use
- time of the day
- type of construction
- surface finish
Infrared cameras should not be used as a do-it-yourself substitute for the knowledge, skills and experience of a trained building & pest inspector.
