Flat Field Correction (Ffc); Save Settings; Surveillance (Auto Scan / Scan List); Auto Scan - FLIR Nexus Configuration Manual

3 Advanced Configuration
3.1.5
A Flat Field Correction operation can be used to correct for non-uniform responsivity within the pixel
array. A shutter activates inside the camera and provides a target of uniform temperature, allowing the
camera to correct for ambient temperature changes and provide the best possible image. The camera
performs FFC at regular intervals or when the ambient temperature changes, but can also be
performed as desired and may cause an overall image improvement. Refer to section 2.8.1 "Image
freezes momentarily" on page 2-17.
3.1.6
All of the IR-0 settings in the Setup page are dynamic and
have an immediate effect, similar to the Advance Sensor
Panel of FSM. When the Save Settings button at the bottom
of the page is selected, the camera will use the saved
settings whenever the power is cycled. To restore the IR camera to the original settings, select the
Factory Defaults button and then click on Save Settings.
3.2
The Setup page also provides access to two convenient Surveillance features, Auto Scan and Scan
List. The web interface can be used to start or stop an Auto Scan or Scan List, and provides limited
configuration and management options. For greater flexibility, the FSM program is especially useful
for setting up and managing Auto Scan, Scan Lists and Presets.
3.2.1
It is possible to operate the camera in a simple back-and-forth (left-right) scan mode. To use the Auto
Scan feature (also known as AutoPan when using serial communications), set the scan width (narrow,
medium, or wide) relative to the current position and the scan speed (fast, medium, or slow) and then
click Start. It is also possible to set absolute left and right limits (in degrees) and the pan speed, and
then start the Auto Scan mode.
3.2.2
In many cases with a pan/tilt camera, it may be useful to designate certain commonly-used pan/tilt
locations as Presets, and to put the camera in Scan List mode where it automatically moves from one
Preset to the next sequentially and repeats the pattern continuously. It may be useful to have several
Scan Lists available, for different times of the day or for different circumstances.
It may be more convenient to use FSM to set up the Presets and Scan Lists, since it allows viewing of
the video at the same time. However, the web interface can be used to add/change a particular Preset
or to set up a simple Scan List.
To create a Scan List with the browser, point the camera toward a preferred location/scene, select a
Preset ID from the pull-down list, and then click on Set. To add a new preset, move the camera to the
next location, select a new Preset ID, and click Set again. Up to 128 Preset locations can be used in a
Scan List. If more than one Scan List has been created using FSM, a particular Scan List can be
loaded from the browser and started.
