About Infrared and how does the Infrared Camera Work

Infrared is an energy which can be described as light we can't see. The infrared camera sees the light as heat and can show this in the Picture. Infrared consists of electromagnetic wavelengths, Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Although we can't see Infrared humans can sense it as heat. All materials whose surface temperature is above absolute zero (-273 °C) emit infrared. "Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum. Far infrared waves are thermal. Objects at temperatures found in buildings radiate heat almost entirely in the far infrared range. Thermal imager's sense infrared which varies with the temperature of the objects in a scene, the image generated provides a thermal signature of the scene. Infrared energy from the objects in the scene are focused by the optics onto an infrared detector. The infrared information is then passed to a signal processor which translates the infrared data into an image that can be viewed and the infrared images along with normal digital images can be stored for later documentation in the cameras reporting software.

How does an Infrared Inspection compare to other types of inspections?

 

Whether it's your home or business from your buildings foundation to its roof infrared provides you by far, the most through non-invasive building inspection and best dollar value for a visual inspection of your property. A Thermographer can look at large areas quickly compared to other types of investigation methods. By analysing Thermal Images of your buildings, water, air and heat leaks, only the faulty areas need to be repaired, sometimes saving thousands of dollars. When Maintenance checks are conducted often small leaks are found that without the aid of Infrared are not visible and would go undetected or in the case of some water leaks until substantial damage has occurred. Thermal Imaging works particularly well for example on finding leaks in membrane roofs and plaster cladding which in the past have been almost impossible to locate. The standard practice in this situation was to completely strip the roof or cladding even when in some cases the membranes or cladding was still in good condition because the exact location of water entry could not be found. Infrared Inspections help avoid costly random destructive testing by pinpointing the exact location of problem areas. To find a leak in a home can be like looking for a needle in a hay stack without an infrared camera. A Thermal Imaging camera is not a magic wand, cannot see through walls and will not expose all defects. A Thermal Imaging camera is only an inspection tool, like all tools there are limitations, but with our experience, other inspection techniques and inspection tools will provide a broader, more comprehensive assessment of the condition of the inspected items.
