ROI
The camera adjustments under the ROI 
heading allow the user to make changes 
to the Region Of Interest. The ROI 
determines what portion of the image is 
considered by the Automatic Gain 
Control (AGC) algorithm. By default all 
of the pixels in the image are 
considered; in some cases it may 
provide an improved image if a portion 
of the image is excluded. For example, 
the sky is generally very cold, so if the ROI excludes the sky it may...

Flat Field Correction (FFC)
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...

3.3 Maintenance Mode
When Maintenance is selected at the top of the page, the configuration changes that are allowed are 
grouped according to the primary buttons on the left: Server, Sensor, and Files. In the previous 
chapter, the Server settings (LAN Settings, Services, and Security Options) were described. The 
following paragraphs describe additional Sensor configuration options available under the 
Maintenance mode that are used in some...

The message at the bottom of the page indicates the 
saved configuration is different than the active 
(running) configuration, and it is necessary to restart 
the server. 
3.3.2 Restarting the Server
After changes have been saved, it is possible to return to the Server Status page and click on the 
Stop button. However, it is even easier to simply click on the green light at the lower left next to “Server 
Running” to stop the server. 
It may...

3.4 Serial Communications (Serial Remote)
In some installations, a serial device such as a keyboard, joystick, or other device is used to control 
camera functions such as pan/tilt or zoom. A serial device can also be used to access functions that 
are specific to thermal cameras, such as changing the polarity from white hot to black hot. Refer to 
section 3.4.1 “AutoPan Function” on page 3-9 for additional information.
The Serial Remote...

If the Pelco D protocol is to be used, select SerialRemote 1 and wait for the page to refresh, and then 
configure the Remote Port Settings such as Speed (baud rate), Data Bits, Parity and Stop Bits. Set the 
Address parameter to the appropriate Pelco address. It may be necessary to use the scroll bar on the 
right side of the page to access the settings.
When Use Preset Map File is set to Yes (the default), then presets (and special functions...

In the Joystick settings, the Mode parameter, when set to FOV Dependant, allows a pan/tilt camera to 
adjust the pan speed automatically, depending on the current field of view (FOV). For a narrow FOV, 
the camera moves more slowly. If you do not want to limit the pan speed according to the FOV, set the 
parameter to Absolute.
The Pilot Mode parameter controls the direction of tilt when the joystick is moved forward or 
backward. When Pilot Mode...

Bits. Select the appropriate Hardware Protocol (RS-422 or RS-232), and set the Address parameter 
to the appropriate Bosch address. If necessary, click Save to save the changes.
Note
Typical Bosch systems operate over a biphase connection and the FLIR cameras do not accept 
biphase signals directly. It may be necessary to install a biphase converter in order to use the Bosch 
protocol.

3.4.2 Serial Extensions
In addition to the set of standard commands that would be used on an ordinary CCTV camera, control 
commands that allow access to more advanced features, or features that are specific to a particular 
type of equipment, are available through extensions to the serial protocol. These extended 
commands are quite useful when controlling features that are specific to FLIR thermal cameras. 
In the Pelco D protocol, these...
