Thermal Imaging for Fever Screening

Thermal cameras utilizes infrared detector to measure skin (surface) temperature.
Health care providers and public officials have been using thermal imaging cameras to quickly scan large numbers of people in public areas for elevated body temperatures that could result from a virus infection.
When elevated body temperature is detected, individual proceeds to designated area for further clinical testing.
Thermal imaging cameras are effective for quick temperature screening of large groups of people.

Benefits of thermal imaging cameras for temperature screening

Non-contact, reduces the chance of spreading infection ordisease

Temperature measurements are immediate—quickly scan large groups of people

No risk to public safety—infrared temperature measurement is completely safe and innocuous

People can be screened while moving, travel is not delayed

Temperature displayed by colors. Detect high temperature easily by red color (based on upper limit) and hot spot marker.

Set a high temperature alarm level. Any temperature detected above alarm level is displayed in red color.

Saturation temperature (above upper level range) is displayed in red color on top of grey thermal image.

Use tape to mark area on the floor 1m to 2m from the camera. Focus camera for selected measurement distance.
People are to move towards the taped area for camera to screen and move out.
If required, use HDMI cable to connect to LCD display for easier monitoring
If alarm high temperature is detected, the person should proceed to further checking with medical thermometer.

An image representing the surfacetemperature of the object
Usually brighter spot is hotter, darker spot is cooler
The image shows the surface temperature and temperature difference on the screening object immediately

Infrared is a form of energy and is a part of electromagnetic spectrum. It is not visible to our human eyes.

Infrared detector inside thermal imager can capture infrared wave.

Thermal Imager detects and converts of energy from infrared spectrum to a visible image.
