Setup — Screening station
3. Restart the camera by disconnecting and then re-connecting the power cable to a
power outlet.
4. 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.
5. Check the camera firewall settings, see section 11.2.3 Firewall configuration.
6.5.3 False triggering
A backdrop prevents background disturbances from reaching the camera. If no backdrop
is used, objects in the background can cause false triggering. To avoid this, you may
need to adjust the Skin maximum temperature setting on the Face detection tab.
The Skin maximum temperature is the highest temperature the system will evaluate. For
example, you can lower this value to prevent a face-like hot lamp from triggering the
alarm.
6.5.4 False alarms
If you are experiencing many false 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 aver-
age temperature 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.
6.5.5 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.
