Temperatures above the Warning threshold
This value can be set to show live temperatures in circles related to subject
’
s heads
as they walk towards the temperature test zone. In the absence of an alarm
threshold it gives an indication to persons passing the Scanning zone that the system
is working and that their temperature has been measured. Typically this value
should be set to one or two degrees below the alarm threshold. If this feature is not
required for display on screen, uncheck the Warning temperature box.

Alarm On/Off delay and Timed Save
The alarm on and off delay affect the alarm hysteresis and when set correctly these
values will avoid alarms flicking on and off for temperatures near to the threshold
temperature value. Once an alarm has been triggered in will stay active for the time
set before the Alarm Off time expires (2 seconds in the illustration shown).
FevIR Cam automatically saves an infrared and visible image when an alarm is
triggered. When “Timed Save (seconds)” is set to zero (the default) only one image
pair is saved. If you set a value for this field then an image will be saved periodically
during an alarm condition at the set time interval.
7.7.4
Saved Image folder
The Saved Image Folder field allows you to store the images in different folder to the
default. This can be to a network drive if appropriately connected and configured.
7.7.5
Alarm Sound
The Alarm sound field allows you to select a different alarm sound to play when an
alarm is triggered. Browse to the appropriate directory and select an alternative
sound file.
