6.1.3 System measuring

When the system has detected a face and is measuring the temperature, a measurement box is displayed.

6.1.4 Screening results

When the system has analyzed the temperature, the screening result is displayed.

No elevated temperature detected.	Elevated temperature detected.

6.1.5 Remove your glasses

Removing eyeglasses is crucial for a correct screening result. If the system detects eyeglasses, a message is displayed.

6.1.6 Too many people

The system can only screen one person at the time. If the system detects more than one face, a message is displayed.

6.1.7 Too cold/warm messages

The system only evaluates temperatures within a certain temperature range. If the measured temperature is outside this range, a message is displayed.

6.2 Operator window

The operator window has one main page with two tabs, Library and Live, and a Settings page.

6.2.1 Library tab

The Library tab shows the File Explorer. Here you can navigate to any folder with saved images.

When you click a folder, the images in that folder are presented in the center pane. When you click an image in the center pane, information about that image is shown in the pane to the right.

Clicking the Library tab displays a toolbar, with options for settings, user manual, support, license, and more.

6.2.1.1 User manual

To access the FLIR Screen-EST user manual, select User manual on the Library page toolbar or go to http://support.flir.com/resources/est .

6.2.2 Live tab

The Live tab is where you initiate and monitor the screening.

The image below shows what the user interface looks like when a camera is connected.

Discovery pane

This pane displays the available cameras. Find the FLIR camera and use the button to the right to connect.
When the Auto-reconnect check box is selected, the camera connects automatically next time FLIR Screen-EST starts.

Camera capture pane

This pane includes buttons for camera control, e.g. autofocus.

Events pane

This pane displays all events and operations performed to a connected camera. Use the buttons to clear or save the logs to a file.

Camera image pane

The live thermal and visual images from the camera is displayed here.
The system is looking for faces in a part of the image which is called the region-of-interest. The dotted box on the images here indicates the region-of-interest for the face detection. The size of the region-of-interest box is defined by a setting (see section 6.3.1 Face detection tab ). You can change the size of the box by a drag-and-drop operation here.

Face detection pane

When the Enable tracking check box is selected, the face detection and screening functionality is enabled. To temporarily stop the screening, clear the check box.
The Alignment data controls are used to align the images from the thermal and visual cameras. When the Auto-alignment check box is selected, the alignment is done automatically. If the images for some reason are not aligned, first clear the Auto-alignment check box and then align the images manually using the PanX and PanY controls.
Moving averages: Value shows the current average. Samples count is the number of samples included in the average calculation. Status shows the sampling status; red when there are no samples, green when the system is adding samples to the average calculation. Hovering over the Value/Samples count/Status area displays a reset button. Click the button to reset the average value.
The Detection status section displays status information and screening results.
- Not available: No face detected.
- Normal: Screening result; normal temperature.
- Abnormally high: Screening result; elevated temperature.
- Glasses: Eyeglasses detected.
- Bad pose: Visitor face is not straight in front of the camera.
- Too far: Visitor face is too far from the camera.
- Too close: Visitor face is too close to the camera.
- Too many: More than one face detected.
- Waiting for exit: System is waiting for the screened person to leave the screening station.
- Below skin temperature: Measured temperature is below the Skin minimum temperature setting (see section 6.3.1 Face detection tab ).
- Above skin temperature: Measured temperature is above the Skin maximum temperature setting (see section 6.3.1 Face detection tab ).
When a screening result is displayed, Face 1 shows the measured temperature.

When the Required manual reset check box is cleared, alarms are automatically reset when the screened person moves away from the camera. When the Required manual reset check box is selected, the operator must manually reset alarms by clicking inside the red Detection status box.

Clicking the Live tab displays a toolbar, with options for connection, settings, camera control, and events.

6.3 Settings page

You access the Settings page via the toolbar on the Library and Live tabs in the operator window.

To exit the Settings page, click Close at the bottom right of the page.

6.3.1 Face detection tab

Moving average

The Default samples count is the number of samples that are included in the average calculation.
When the Reset moving average after specified time check box is selected, the system automatically resets the moving average when the specified time has elapsed since the last screening. When the system starts to build up a new moving average, the first measurement will be evaluated based on the Temperature after reset value. For more information, see section 5.3.1 Reset of moving average .

Face detection status

The screening algorithm only evaluates temperatures between the Skin maximum temperature and Skin minimum temperature values. It is recommended to use the default values.
There will be an alarm if the measured temperature is more than the sum of the moving average and the Allowed deviation value. Setting a low value will detect smaller elevations in skin temperatures, but it will also generate more false alarms. With a high value, there is a risk of missing people with elevated skin temperatures.

Detector type

The application can use either the thermal data stream or the visual data stream for face detection and definition of measurement area.

Use the Detector type list to select thermal or visual face detection.

Image settings

These settings apply to the live camera images in the operator window.

Select the Mirror image check boxes to mirror (flip) the image.
Use the Image orientation list to select portrait or landscape orientation.

Region of interest

The system is looking for faces in a part of the image which is called the region-of-interest. On the Live page, the dotted box indicates the region-of-interest for the face detection.

The Initial size values define the size of the region-of-interest box (in percentage of the image).

6.3.2 User screen tab

The settings on the User screen tab apply to the visitor window.

Custom status messages

Use these fields to change the status messages. You may, for example, want to translate the messages to your local language.

Use the Swap video streams check box to select the display of thermal or visual video in the main image.

6.3.3 Output tab

FLIR Screen-EST can be configured to save images and data when an elevated skin temperature is detected. It is the responsibility of your company to handle any saved images and data in accordance with applicable local data protection laws.

Snapshot options

When the Save dual snapshot separately check box is selected, a separate visual image will be saved in addition to the combined thermal and visual image.

Output options

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.

Alarm

When the Log alarms to output folder check box is selected, an image (combined thermal and visual image) and a data file (*.csv) is automatically saved when an elevated skin temperature is detected. By default, this check box is cleared and no images are saved automatically.
When the Use sound alarm check box is selected, there will be a sound when an elevated temperature is detected.

Digital output

The screening result can trigger an external device, such as a gate, lights, or a siren, connected to the digital I/O connector on the camera.

Cameras that support multiple digital outputs will send a signal on digital output 1 for a positive condition (Elevated temperature) and a signal on digital output 2 for a negative condition (Normal temperature).

When the Enable digital output check box is selected, a digital pulse will be output after a Normal temperature or Elevated temperature screening result.
Use the Elevated temperature signal’s timespan and Normal temperature signal’s timespan fields to define the time (in milliseconds) that the digital output is enabled when a positive/negative result is detected by the camera. Set the value to 0 milliseconds to make the output enabled as long as a positive/negative condition is met.

6.3.4 Webhooks tab

The Webhooks tab is used to control the webhooks functionality. For more information, see section 8.2 Webhooks .

Use the button to activate/deactivate webhooks. The settings can only be changed when webhooks is inactive (red Off).
