ThermoScreen Advantages

Advantages over Clinical Thermometers

ThermoScreen can screen over 1000 subjects per hour, more than 10 times the screening rate using clinical oral or ear thermometers.
ThermoScreen measurements do not require contact with subjects and are conducted at a distance of 3 meters (10 feet).
ThermoScreen performs evaluations based on the temperatures of previously screened subjects, unlike clinical thermometers whose evaluations are based on comparisons to a fixed temperature threshold. Studies indicate that temperature screening should be evaluated in relation to the temperature characteristics of specific subject groups.
All subjects can be screened using a single ThermoScreen system. Studies confirm the importance of using the same instrument when screening subject groups in order to obtain repeatable results.
The accuracy of ThermoScreen measurements are not influenced by operator skill, unlike oral, ear, and temporal thermometers measurements.
ThermoScreen measurements are not influenced by prior consumption of hot or cold liquids, unlike oral thermometer measurements.

Advantages over Competing Systems

Highest Accuracy

ThermoScreen is designed to be intrinsically accurate; a reference calibration source is not required during operation. Each ThermoScreen system undergoes an extensive calibration process. During operation, software algorithms provide real-time compensation for environmental variables that can affect screening results. Furthermore, ThermoScreen hardware is designed to prevent unwanted radiant energy from affecting screening measurements.

Many competing fever screening systems require a reference calibration source to be placed within view of the camera during operation to correct for camera inaccuracy. The use of an external reference source adds complexity, increases setup time, decreases portability, and places restrictions on the areas in which the system can be operated. In addition, the use of a reference source can lead to significant instability and measurement errors if misalignment occurs between the camera and source or if environmental factors cause the source temperature to drift during operation.

Automated Screening Mode

Automated screening mode provides the most accurate and effective method of mass fever screening. ThermoScreen guides subjects through the screening process by issuing verbal commands, thus reducing the demands on operators, allowing them to focus their attention on processing fever violations. During the screening process, individuals are required to stand still to prevent image blur from degrading measurement accuracy.

Because the temperature threshold that indicates a fever can vary depending on time of day and other factors affecting subject groups, individuals are evaluated based on the screening measurements of previously screened subjects, not on a fixed temperature threshold. Evaluating subjects in this manner results in a screening process that minimizes missed detections and false violations.
