Whether it's an air leak, a gap in insulation, or moisture hiding in a wall, what a home inspector looks for isn't always easy to see with the human eye. That's why JLH Inspections utilizes and rely on home inspection infrared cameras in every home inspection. Infrared cameras are another tool to identify home defects.
Infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat.
Infrared proximity sensors work by sending out a beam of infrared light, and then computing the distance to any nearby objects by employing the characteristics of the returned signal.
Infrared cameras make it quick and easy to identify moisture, air leaks, heat loss, poor insulation, bad electrical systems, and other defects.
Within the electromagnetic spectrum, infrared waves occur at frequencies above those of microwaves and just below those of red visible light, hence the name "infrared."
IR frequencies range from about 300 gigahertz (GHz) up to about 400 terahertz (THz), and wavelengths are estimated to range between 1,000 micrometers (µm) and 760 nanometers (2.9921 inches)
Most important to know, for those who are worried about safety, is that infrared cameras, like any other cameras, capture energy emitted from the body and do not generate any radiation themselves. So there is no risk from them.
