What is building, house, electrical or mechanical equipment infrared, thermal imaging Inspection/Survey?
Infrared thermography, thermal imaging, and thermal video are examples of infrared imaging science. Thermography has a long history, although its use has increased dramatically with the power transmission, distribution, utility, commercial and industrial applications. Everything you see around you (objects), be it electrical/mechanical equipment, power lines, substations, heater, cold storage, fridge even wall, car, wood, (everything) has a certain temperature and they all emit waves of energy called ‘Infrared radiation’ (IR). The hotter the object is, the more energy it emits. A thermal imaging camera translates this energy waves into a viewable image, which shows a “heat picture” of the object the camera is pointing towards at the time. The actual detector we use within our thermal imaging cameras are somewhat similar to the human eye, and are very (hundred times) more sensitive.
These Aitur Group‘s pictures below are simple examples of IR images.

On these pictures, a hotter object is shown as yellow white and a cooler object shows as dark blue. This is the basic concept of infrared imaging science. A thermal imaging/infrared camera can only detect/identify the temperature difference on any given surface. Thermal imaging/infrared camera cannot see through solid materials like drywall, plaster, concrete, steel, wood, doors and etc.
