Infrared Cameras require a direct line of site to record an accurate image.
These direct temperature measurements are used to determine which components within an assembly are faulty, how critical the faults are, and what actions need to be taken to correct them.
However, the National Fire Protection Association's (NFPA) specification, NFPA 70E, establishes guidelines for safe work practices around live electrical components. These guidelines are changing how thermographers can conduct thermal inspections of low, medium and high voltage electrical equipment.
An infrared window provides a thermal imager (IR camera) direct line of site to inspect electrical cabinets and other systems without having to open the enclosure to the environment.

This assists in complying with the safety recommendations of NFPA70e and other bodies.
IRISS Infrared windows and grills are used to remove the risk to thermographers by ensuring that they are never exposed to energized electrical equipment while inspecting equipment, therefore ensuring safe IR inspections of electrical switchgear.
Additionally the use of this type of inspection methodology means that the switchgear always remains shut during the inspection eliminating 99.9% of the causes of arc flash.
