Infrared Imaging Systems for Human Fever Screening


For general camera specifications please see Infrasight IS640 radiometric camera specifications.

Note: Thermoscreen cameras undergo a rigorous calibration process specifically designed to maximize accuracy for human fever screening measurements. Calibration temperature range and sensitivity are optimized to provide the highest sensitivity and precision when measuring the temperature of human skin. For this reason, the following temperature measurement specifications supercede the general camera specifications.
