Digital thermal imaging cameras have established themselves as invaluable tools for building safety inspections. Thermal imaging cameras such as forward-looking infrared (FLIR) cameras perform noncontact temperature measurements to detect anomalous heat patterns in buildings. They can be used, for example, to find energy-wasting leaks in construction or gaps in electrical insulation. They can also provide heat signatures that reveal the condition of a power generator or motor in factories and production plants. Since some building inspections are performed in potentially dangerous environments, a safe imaging camera can provide a sharp vision of a safe building. But choosing the right digital or thermal imaging camera for a job requires an understanding of how these instruments work and some insight into some of the more important performance specifications. The right camera can pack a great deal of safety inspection into a portable handheld instrument.
