Camera web interface

When an alarm is triggered, the camera can perform one or more tasks, e.g. save an im-
age or video sequence to camera memory, or send the image/video by e-mail to prede-
fined recipients or to an FTP site. The camera can also further trigger a variety of
external devices, using the digital output.
All active alarms are listed in the Active alarms section. A triggered alarm turns red in the
Active alarms section. Also, the label of the measurement tool in the image turns red.
11.4.2.1 Setting an alarm based on a measurement result
To configure an alarm based on the measurement result from a spot, box, or delta meas-
urement tool, follow this procedure:
1. In the Active Measurements section, click the plus sign under Add alarm next to the
measurement result to be used for the alarm. The Add alarm dialog box appears.
2. In the Alarm label section, type an Alarm name.
3. In the Trigger section, select the Condition and temperatures that will trigger this
alarm:
Below Triggers an alarm when the temperature is below the specified Thresh-
old value. Also type a Hysteresis value.
Above Triggers an alarm when the temperature is above the specified Thresh-
old value. Also type a Hysteresis value.
Interval Triggers an alarm when the temperature is within the specified Min val-
ue and Max value.
Hysteresis is the interval within which the temperature value is allowed to vary without
causing a change in the trigger. If the threshold is set above 30.0°C and the hystere-
sis is set at 2.0°C, the trigger goes high when the temperature rises above 30.0°C
and stays high until the temperature drops below 28.0°C. In contrast, if the threshold
is set below 30.0°C, and the same hysteresis value is kept, the trigger goes high if
the temperature drops below 30.0°C and stays high until the temperature rises above
32.0°C.
4. In the Threshold time box, type the amount of time that has to pass before an alarm
is triggered. This can be used to avoid false alarms.
5. In the Action section, select which actions the camera will perform when an alarm is
triggered:
Digital OUT Outputs a digital pulse. Also, type a pulse length (in millisec-
onds) in the Pulse time box.
E-mail Automatically sends the captured Image, Result, or Video to the
recipients defined in Settings > Alarm recipients.
Send to FTP
Automatically sends the captured Image or Video to the FTP
site defined in Settings > Alarm recipients.
Save to camera
Automatically saves the captured Image or Video to the memo-
ry of the camera.
During alarm
Temporarily disables the periodic calibration while the image/
video is being captured.
The image/video can later be viewed and managed under the Library tab:
• the captured image frame that triggered the alarm,
• the 5 second video sequence when the alarm was triggered.
6. When completed, click Set alarm. The alarm is now listed under Active alarms.
