6 Setup — Screening station

This chapter describes how to set up a FLIR EST Kiosk screening station.

For accurate and efficient screening, it is recommended to set up the screening station as outlined in section 6.1 Screening station setup .
For step-by-step instructions, see section 6.3 Step-by-step setup instructions .
If you run into problems, see section 6.6 Trouble shooting .

6.1 Screening station setup

The figure below shows a typical screening station setup. For more information, see chapter 7 Description — Screening station .

FLIR EST Kiosk.

Screening position.
It is important to clearly mark the screening position (where the person should stand for the screening). The distance from the foot of the FLIR EST Kiosk to the center of the screening position shall be 120 cm (47 in.).

Queueing system, e.g. barriers and arrow floor stickers.
The queueing system will guide the visitors into the screening station, to the correct screening position, and out of the screening station. A recommended standard is to keep the queue at least 90 cm (36 in.) wide. To make sure people do not cut the corner and end up too close to the FLIR EST Kiosk, about 45 cm (18 in.) should be added to the barrier leading in to the screening station.

Optional: Backdrop.
A backdrop may be needed to prevent background disturbances from reaching the camera, such as passing or queueing people.

Additional, not in the figure:

Optional: Operator display.
Secondary display placed near the operator for monitoring.
Optional: Information roll-up.
Roll-up that informs people what the screening is about and why they need to do it.

6.5 Settings for 24/7 operation

If you plan to run the screening station 24/7 without any operator interaction, you may want to enable some automatic functions.

6.5.1 Automatic reset of moving average

If there has been a long time since the last screening, the moving average may not be at the correct level and there is a risk for false negatives. One way of limiting this risk is to reset the moving average, manually or automatically. The system will then start to build up a new moving average. For more information, see section 10.4.3.1 Reset of moving average .

After an automatic reset of the moving average, the system will evaluate also the first screened person (which is not the case after a manual reset). Since there is no average to compare with after the reset, a fixed temperature value will be used for the evaluation of the first person.

The default fixed temperature value can be used as a starting point. However, the appropriate value depends on factors such as environmental conditions and time of day. It is recommended to establish a fixed temperature value adapted to your local conditions.

6.5.1.1 Establish fixed temperature value

The fixed temperature value can be established by checking the measured temperatures in FLIR Screen-EST at the same time for three days in a row and then use the highest of these temperatures.

To establish the fixed temperature value, do the following:

Make a decision on the likely time for the first person to enter the screening station after a reset of the moving average.

At the same time (as decided above) for three days in a row, check the operator window and make a note of the measured temperatures.

Use the highest of the recorded temperatures as your fixed temperature value.

6.5.1.2 Enable automatic reset

To enable automatic reset of the moving average, do the following:

Open the Settings page, see section 6.4.1 Open the Settings page .

On the Face detection tab, select the Reset moving average after specified time check box.

In the Reset after fields, enter the time (hours:minutes).

In the Temperature after reset field, enter your fixed temperature value (see section 6.5.1.1 Establish fixed temperature value ).

6.5.2 Automatic restart of screening

Windows devices are sometimes forced to restart, for example after a Windows update, which also closes all applications. The device may also shut down completely if the battery level is very low. By a setting, you can ensure that FLIR Screen-EST starts up automatically when the device restarts.

There is also a setting that will make FLIR Screen-EST restart automatically after an unexpected crash or if the application is not responding.

FLIR Screen-EST stores all settings and states, including the moving average, during an on-going screening session. When an automatic function starts FLIR Screen-EST after an unexpected system restart or application failure, the stored values will be used and the screening can continue without any operator interaction.

To enable automatic restart of the screening, do the following:

Open the Settings page, see section 6.4.1 Open the Settings page .

On the General tab, do the following:

Select the Start application on system start-up check box to enable automatic start of FLIR Screen-EST.
Select the Enable application monitoring check box to enable automatic restart after an application failure.

In the operator window, make sure the Auto-reconnect check box is selected. This will make the camera connect automatically, allowing the screening to start again.

6.6 Trouble shooting

6.6.1 Must enter license key every time

If you must enter the license key every time you start FLIR Screen-EST, the application has not been successfully activated.

Follow the instructions in section 5.4 Activate FLIR Screen-EST‎ . When you have entered the license key, make sure you tap the Validate button (not the Demo mode button).

6.6.2 FLIR Screen-EST‎ cannot find the camera

If FLIR Screen-EST cannot find the camera, try the following:

Restart the FLIR Screen-EST application.

Restart the tablet.

Restart the camera by disconnecting and then re-connecting the power cable to a power outlet.

Check the tablet firewall settings.
Open the Windows Defender Security Center and go to the Firewall settings. Make sure the FLIR Screen-EST application is allowed to communicate through the firewall.

Check the camera firewall settings, see section 11.2.3 Firewall configuration .

6.6.3 False triggering

Persons and objects in the background can cause false triggering. To prevent background disturbances from reaching the camera, it is recommended to place a backdrop behind the screening position.

6.6.4 False alarms

If you are experiencing many false screening alarms, you may need to adjust the Allowed deviation setting on the Face detection tab.

The Allowed deviation is how much the measured temperature can differ from the moving average without triggering an alarm. A higher value will lead to fewer false alarms, but there will also be a risk of missing people with elevated skin temperatures. A lower value will detect smaller elevations in skin temperatures, but it will also generate more false alarms.

6.6.5 Cannot screen short/tall persons

The screening station is set up to screen persons with a height of 145-190 cm (4.8–6.2 ft.).

The screened person shall stand at the screening position (not closer or further away from the camera).

Tall persons may have to bend their knees.
Short persons may need e.g. a high chair to sit on.

The screening works best when the FLIR Screen-EST is configured for portrait mode. On the Settings page, select the Face detection tab and ensure the following settings:

Set Image orientation = Portrait.
Set Region of interest: Initial horizontal size = 80,0 and Initial vertical size = 98.0.
