Mass Human Fever Screening

¡@

ThermoScreen provides the most accurate method of mass screening for high body temperatures that may indicate a fever.  By identifying people who may be infected, ThermoScreen can help prevent the spread of contagious diseases such as influenza, H1N1, Avian flu (bird flu) and SARS.

Description

¡@

Designed specifically for mass fever screening, the ThermoScreen infrared fever screening system was originally developed in response to the need to screen large numbers of individuals for fever during the SARS outbreak in 2003.  ThermoScreen thermal imaging technology allows subjects to be screened at a distance, without contact,  providing a discreet and safe method of detecting feverish individuals.  ThermoScreen is capable of evaluating hundreds of individuals per minute so as not to restrict pedestrian flow.  ThermoScreen is currently used in hospitals, airports, seaports, and businesses to help prevent the spread of contagious diseases such as influenza, H1N1,  Avian flu (bird flu), and SARS.

¡@

To achieve the high accuracy required for reliable fever detection, each ThermoScreen infrared camera undergoes a rigorous calibration process.  Furthermore, OptoTherm employs sophisticated hardware and software developments to compensate for environmental changes to further improve the accuracy of screening measurements.

¡@

ThermoScreen is sold as a complete, fully tested system including a PC with preinstalled hardware and software.

How It Works

¡@

ThermoScreen is a completely passive device and emits no harmful radiation.  The ThermoScreen thermal imaging camera measures skin temperature by detecting and quantifying the infrared energy that is continuously being emitted from the human body.  As individuals walk past the screening station, skin temperatures above a pre-defined threshold are detected and displayed in bright colors on the computer screen.  An audible alarm is activated to notify personnel that a temperature violation has occurred.  To allow continued screening of individuals during a violation, the three most recent violation images are displayed on the screen.

When mounted in the mobile computer stand, ThermoScreen can easily be moved to alternate locations to screen additional groups of people or to accommodate changes in pedestrian
