What is a thermal imaging camera used for?
Thermal Imaging Cameras can, when used by a professional inspector assist in the detection of current Termite Activity within the structure. Termite workings generate heat, especially the nest and can readily be detected by a Thermal Imaging Camera. Our firm has located several nests within the walls of dwellings & most frequently behind tiled shower walls! Termite Nests in these locations, without the aid of the Thermal Imaging camera, may have been impossible to find!
Thermal imaging is the use of a thermal imaging camera to "see" thermal energy emitted from an object. Thermal imaging cameras produce images of invisible infrared or "heat" radiation. Based on temperature differences between objects, thermal imaging produces a crisp image on which the smallest of details can be seen. They work both during daytime and night time.
The higher the object’s temperature, the greater the IR radiation emitted. Infrared allows us to see what our eyes cannot. Infrared thermography cameras produce images of invisible infrared or “heat” radiation and provide precise non-contact temperature measurement capabilities.
Most FLIR Systems thermal imaging cameras contain an uncooled Vanadium Oxide detector. Not only does this produce excellent quality thermal images, thermal imaging technology requires no additional lighting or illumination.
Are there any limitations to thermal imaging cameras?
Yes! Thermal energy can be reflected off of shiny surfaces such as polished metal and glass. Thermal imaging cameras cannot see through glass. If you stand in front of a window while looking at a thermal imaging camera, you will see yourself in the window because of the thermal energy reflecting off the glass.
Regardless of what you may see in movies, thermal imaging cameras cannot see through walls.
It is also important to know that thermal imaging cameras should not be used as the sole deciding factor that a problem exists. Using other instruments such as a moisture encounter meter, borescope, & 'more invasive' inspections are also strongly advised to determine pest activity within a structure.
