FLIR EST Thermal Screening
Solutions
2
FLIR Systems provides different screening solutions for detection of elevated skin tem-
peratures using thermal cameras.
No thermal camera can detect or diagnose a virus or infection, but with a FLIR EST Ther-
mal Screening Solution it is possible to identify individuals with skin temperatures that
are above a specified threshold. An elevated temperature may be one indicator that the
person being screened may have a fever.
The FLIR EST Thermal Screening system measures the temperature of the skin around
the tear duct. An alarm will trigger when the measured temperature is higher than the
sum of a reference temperature and a specified allowed deviation.
To improve the accuracy of the screening results, it is important to set up the screening
station correctly.
Since the FLIR EST Thermal Screening systems measure the surface temperature of the
tear duct, the measured temperatures are lower than the ones you may be used to in a
fever context. Note that the FLIR EST Thermal Screening systems cannot measure core
body temperature or diagnose a fever.
It is up to you to set up a suitable core body temperature measuring process, and a proc-
ess for those individuals where the system has indicated an elevated skin temperature in
accordance with applicable local data protection, employment, and health & safety laws.

Screening station — General
description
3
3.1 Overview
The screening station typically consists of a FLIR thermal camera, a FLIR EST Thermal
Screening application (e.g. desktop software or camera mode), a clearly defined screen-
ing position, and a backdrop.
For improved measurement accuracy, it is important that the screened person is at the
correct distance from the camera. The screening position indicates where the person
shall stand for the screening.
A backdrop shall be placed behind the screening position. The backdrop is needed to
prevent any disturbing reflections, people, and light in the background from reaching the
camera.
The thermal camera measures the temperature at the tear duct of the screened person.
The FLIR EST Thermal Screening application analyzes the measured temperature and
displays a screening result.
3.2 Typical setup

2. Screening position
3. Thermal camera
4. Stand
5. Display
3.2.1 Mounting and placement
• The camera shall be placed under the display.
• The screening position shall be perpendicular to the camera. The distance between
the camera and the screening position shall be 1–2 m (3–6 ft.).
• The camera shall be angled upwards, so that it aims at the head of a person standing
at the screening position.
• A backdrop shall be placed behind the screening position, providing a uniform and
non-reflective background.
3.3 Environmental considerations
For more accurate screening results, the following factors related to the environment
around the screening area should be considered:
• When the outdoors temperature differs from the temperature at the screening station,
it is essential that persons entering the building wait at least 1 minute before doing the
#T810558; r. AC/68383/68383; en-US 3

Screening station — General description

screening. For instance, people riding a bike will be significantly colder in the eye even
at relatively warm weather. But the eye will quickly (1-3 minutes) adapt to the core
temperature once indoors.
• The screening area should have a non-reflective background and minimal reflected in-
frared radiation from the surroundings. This can be achieved by placing a backdrop
behind the screened person.
• Make sure there are no glass windows or doors in front of the camera. The windows
can cause reflections and incorrect temperature measurements.
• Make sure there are no heat sources near the screened person, including hot lamps,
sun light, electrical equipment, etc. This can increase the skin temperature.
• Make sure no beams from intensive energy sources go into the thermal camera. This
includes devices that emit laser radiation, or the sun. The beams can have an un-
wanted effect on the accuracy of the camera. They can also cause damage to the
camera.
• The measurements can be influenced if the screened person is sweating. For that
reason, the relative humidity in the screening area should be maintained below 50 %
and the temperature below 24°C (75°F).
• Prevent drafts from sources such as air conditioning from blowing directly onto the
screened person. The air flow can cause cooling or heating of the face.
3.4 Privacy and processes
FLIR EST Thermal Screening Solutions offer a wide variety of (default) settings and op-
tions to allow you to use FLIR cameras in accordance with your needs and in compliance
with any applicable laws and guidelines.
In addition to setting up the screening station equipment, you must also consider person-
al integrity and processes for elevated temperature alarms.
• Personal integrity
You must make decisions on how to handle personal integrity, e.g. show/hide visitor
display for others than the screened person, have/not have an alarm sound.
By default only the following are shown on the display: live (thermal) video and
screening result (but not the exact temperature: if exceeding a selected temperature
difference, to determine reference temperature, and for actual screening results, indi-
cated as “elevated/no elevated temperature detected”).
• Process for alarms
You must establish a process for those individuals where the system has indicated an
elevated temperature, e.g. let the person sit down for 10 minutes and then do the
screening again, further evaluation by medically trained personnel in accordance with
applicable local data protection, employment, and health & safety laws.
3.5 Equipment and material
The following equipment is needed at the screening station:
• FLIR thermal camera with EST software and EST accessories.
• FLIR EST Thermal Screening application (e.g. desktop software, camera mode).
• Visitor display.
• Mounting equipment for display and camera; e.g. stand, wall mount, tripod, bar table.
• Backdrop, providing a uniform and non-reflective background.
• Marker to indicate the screening position; e.g. floor sticker, tape.

Screening with the FLIR Screen
EST application
4
FLIR Screen EST is an application for detection of elevated skin temperatures using ther-
mal cameras.
Using face-detection capabilities, the system determines an average skin temperature of
people entering the camera field-of-view and automatically alarms on readings that ex-
ceed a selected temperature difference.
4.1 Screening procedure
The screening of a person is performed in a few steps.
The person stands in front of the screening station, looking at the display. When the sys-
tem detects a face, live video is shown on the display. The display graphics guide the
person into the correct position for the screening. When the system has measured the
temperature, the screening result is shown on the display.
Note New versions of the FLIR Screen ESTapplication are continuously released. The
user interface may differ depending on the software version.
Screening procedure:
1. The system is in idle mode. Go forward and stand in front of the display. Make sure
your eyes are not covered by eyeglasses, hair, or other items.
2. You are too far from the camera. Move closer.
3. You are too close to the camera. Move further back.

7.5.2 User interface
The FLIR Screen EST application consists of two windows:
• The operator window is used by the operator for setup, control, and monitoring.
• The screening window is what the screened person sees.
The operator window has three pages:
• The Live page is where you connect to the camera and control the screening.
• On the Library page you can navigate to any saved images.
• The Settings page is used to change the settings.
7.5.3 Working principle
The system calculates a moving average temperature value based on a specified num-
ber of samples. Only temperatures between specified minimum and maximum tempera-
tures are included in the average calculation. Persons with an elevated temperature do
not contribute to the average calculation.
The system detects and measures the temperature of the hottest spot within a face de-
tection box. An alarm will trigger when the measured temperature is higher than the
alarm limit. The alarm limit is the sum of the average temperature and a specified allowed
deviation.
The face detection box is looking for faces in a part of the image which is called the re-
gion-of-interest. The size and position of the region-of-interest can be changed on the
Live page.

age calculation. In the Face detection pane, the status indicator shows the sampling
status; red when there are no samples, yellow when the system is collecting samples,
green when the number of registered samples is according to the Samples count
setting.
3. When the status indicator is green (OK), the system is ready for screening.
The Detection status shows the screening result; green when the temperature is nor-
mal, red when an elevated temperature is detected, grey when no result is available.
4. When the system is ready for screening, the screening window also becomes
operational.
7.8 Configure FLIR Screen EST
7.8.1 Personal integrity
Configuring the FLIR Screen EST application also involves settings related to personal
integrity.
You need to make decisions on the following:
• Should there be an alarm sound when the system detects an elevated temperature?
• Should a combined thermal and visual image and a data file be saved when the sys-
tem detects an elevated temperature?
• Should a separate visual image be saved, in addition to the combined thermal and
visual image?
• What output folder should be used for any saved images and data?
Note By default, no images are saved when the system detects an elevated
temperature.
7.8.2 Select the FLIR Screen EST settings
You access the Settings page via the toolbar on the Library and Live pages in the opera-
tor window.
For most settings in the FLIR Screen EST application, it is recommended to use the de-
fault settings.
The settings that you may want to change are on the Face detection and General tabs
on the Settings page.
7.8.2.1 Face detection tab
Face detection status
• The Allowed deviation value is the allowed deviation from the average temperature. If
the measured temperature of the screened person is more than the sum of this value
and the average temperature, the elevated skin temperature alarm will trigger. It is rec-
ommended to use the default setting, but you can experiment with other values.

Alarm
• Select the Log alarms to output folder check box to automatically save an image and
a data file (*.csv) when the system detects an elevated temperature. By default, this
check box is cleared and no images are saved automatically.
• Select the Use sound alarm check box to have a sound when an elevated temperature
is detected.
Expected face size
• For accurate measurements, it is important that the screened person is at the correct
distance from the camera. If the person is too far, the face will be too small for an ac-
curate measurement. If the person is too close, the camera focus will be incorrect.
To make sure the person is in a correct position, the system will only measure temper-
atures when the person’s face covers a specified percentage of the so called region-
of-interest. The Minimum value and Maximum value settings are used to specify this
percentage.
Depending on factors such as the distance to the camera and the type of camera lens,
you may have to adjust the Minimum value and Maximum value settings.
Note On the Live page you can change the size of the region-of-interest. If you do
that, you may have to adjust the Minimum value and Maximum value settings.
Custom status messages
• You can change the text that the screened person sees on the display. You may, for
example, want to add instructions for what the person shall do in case of a detected
elevated temperature.
Swap video streams (applicable to the screening window)
• Select the Swap video streams check box to change the display of the thermal and
visual video streams.
• Select the Mirror image horizontally check box to mirror (flip) the image.
• Select the Swap direction animations check box to change the direction of the arrows
that indicate that the person shall move closer or further back.
When all settings are completed, click Close in the bottom right corner of the page. This
closes the Settings page.
7.8.2.2 General tab
When the Log alarms to output folder check box on the Face detection tab is selected,
an image and a data file (*.csv) is automatically saved when an elevated skin tempera-
ture is detected. It is also possible to save images manually on the Live page.
Save dual snapshot separately
• When this check box is cleared, a combined thermal and visual image will be saved.
• When this check box is selected, a separate visual image will be saved in addition to
the combined thermal and visual image.
When the Open output folder after saving snapshot check box is selected, the folder with
the saved image will open when the saving is completed.
To change the file path to the folder where you want to store saved images, click Browse
and then select the folder.
