When the LAN settings are changed and the Save button is clicked, a pop-up message will appear to 
indicate the network interface should be restarted. 
Once all the changes have been made and saved, scroll to the bottom of the page and click on the 
Restart Network button.
If the Hostname is changed, the new name may not show up in FSM until the camera is rebooted. To 
reboot the camera, save any configuration changes, then select Server Status and click the Reboot 
button.
Note
To reset the IP address to the factory default, refer to section 3.10 “Restoring the Factory Settings” on 
page 3-18.
The IP address is temporarily displayed on the video for a short while after the camera boots up. If 
you are unsure what the camera IP address is set to, it may useful to reboot the camera and watch 
for the IP Address information after the camera boots up.

2.8 Troubleshooting Tips
If you need help during the installation process, contact your local FLIR representative or, call 877-
773-3547 inside the US. FLIR Systems, Inc. offers a comprehensive selection of training courses to 
help you to get the best performance and value from your thermal imaging camera. Find out more at 
the FLIR training web page: 
http://www.flir.com/training.
2.8.1Image freezes momentarily
By design, the camera image will freeze momentarily on a periodic basis during the Flat Field 
Correction (FFC) cycle (also known as Non-Uniformity Correction or NUC). Every few minutes, the 
image will momentarily freeze for a fraction of a second while the camera performs a flat field 
correction. 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. 
Just prior to the FFC, a small green square will appear in the corner of the screen.
Using FSM, it is possible to adjust the frequency of how often the FFC operation occurs. Using the 
Advanced Sensor Control, it is possible to change the FFC interval or to disable the automatic FFC 
entirely by setting it to Manual mode. For the best possible image, it is recommended the factory 
settings are used.
2.8.2 No video
If the camera will not produce an image, check the video connection at the camera and at your 
display. If the connectors appear to be properly connected but the camera still does not produce an 
image, ensure that power has been properly applied to the camera and the circuit breaker is set 
properly. If a fuse was used, be sure the fuse is not blown. If the video cabling is suspected as a 
possible source of the problem, plug a monitor into the RCA connection inside the camera and 
determine if it produces an image. 
When the camera is powered on, it will do a NUC operation shortly after startup. If you are uncertain if 
the camera is receiving power, it may be useful to listen to the camera to hear if the click-click of the 
shutter mechanism can be heard. It may be only be possible to perform this test when the camera is 
on a work bench rather than in its installed position.
If the camera still does not produce an image, contact the FLIR dealer or reseller who provided the 
camera, or contact FLIR directly (contact information is provided on the rear cover of this manual).
2.8.3 Performance varies with time of day
You may observe differences in the way the camera performs at different times of the day, due to the 
diurnal cycle of the sun. Recall that the camera produces an image based on temperature 
differences. 
At certain times of the day, such as just before dawn, the objects in the image scene may all be 
roughly the same temperature, compared to other times of the day. Compare this to imagery right 
after sunset, when objects in the image may be radiating heat energy that has been absorbed during 
the day due to solar loading. Greater temperature differences in the scene generally will allow the 
camera to produce high-contrast imagery. 
Performance may also be affected when objects in the scene are wet rather than dry, such as on a 
foggy day or in the early morning when everything may be coated with dew. Under these conditions, it 
may be difficult for the camera to show the temperature the object itself, rather than of the water 
coating.

2.8.4 Unable To Communicate Over Ethernet
First check to ensure the physical connections are intact and that the camera is powered on and 
providing analog video to the monitor. When the camera is turned on, confirm the startup information 
is displayed on the analog monitor after approximately 90 seconds. For example:
S/N: 1234567
IP Addr: 192.168.250.116
Confirm that the IP address for the PC (for example, 192.168.250.1) is on the same network as the 
camera. 
Next determine if Windows Personal Firewall is blocking the packets. You can turn off the firewall or 
add an exception for the FSM program. Typically when FSM runs for the first time, a pop-up 
notification may ask for permission to allow the FLIR Sensors Manager (fsm.exe) to communicate on 
the network. Select the check boxes (domain/private/public) that are appropriate for your network. 
By default the camera will broadcast a “discovery” packet two times per second. When FSM starts up, 
it listens to the network for the discovery packets. If no cameras are listed in the Discovered Servers 
list, press the Refresh button. If the list is still empty, it indicates no discovery packets were received. 
This could be due to a wide variety of problems with the network, the PC, or the camera. 
If necessary, use a packet sniffer utility such as Wireshark to capture packets and confirm the packets 
are being received by the PC from the camera.

2.8.5 Unable to control the camera
If the camera does not respond to commands from the web interface (for example, the camera does 
not zoom when the zoom in button is clicked), you may not have control of the camera. By default the 
web tool will automatically request control of the camera when a command is issued, but if another 
user has control of the camera, that user may refuse to release control. Ensure the Control light 
indication is green to confirm if you have control of the camera.
If the camera does not respond to commands from FSM, the camera may not be the “Active” camera, 
or you may not have control of the camera. By default FSM will automatically request control of the 
camera and make it active, but if there are multiple cameras and/or multiple FSM clients, it may be 
necessary to manually make the camera active and take control of it. 
In the Sensors Panel, if the camera is the active sensor, there will be an “(Active)” 
notification next to the name of the camera. Only one camera or sensor can be 
active at a time. To make the camera active, right click on the icon to the left of the 
camera name and select “Set Active”, or simply double-click on the icon.
The icon to the left of the camera name indicates the status of the sensor. The following is a list of the 
possible icons and the meaning of each one.
Connected and Controlled
This icon indicates the camera has been discovered and added to the list of active servers, and the 
camera is actively “connected” to the FSM client and receiving status updates. The joystick in the icon 
indicates the user has control of the camera. To release control of the camera, right click on the icon 
and select “Release Control”. 
Discovered
This icon indicates the camera has been discovered and added to the list of 
active servers, but the camera is not actively “connected” to FSM, and 
therefore FSM is not receiving status updates. To connect to the camera, right 
click on the icon and select “Connect”. Alternatively, it is possible to double-
click the icon to connect.
Connected
This icon indicates the camera has been discovered and added to the list of 
active servers, and the camera is actively “connected” to FSM and receiving 
status updates. To take control of the camera, right click on the icon and 
select “Request Control”. Alternatively, it is possible to double-click the icon to 
take control.
Not Connected
This icon indicates the camera has been discovered and added to the list of 
active servers, and FSM is trying to connect to the camera, but some kind of problem is preventing 
FSM from receiving status updates the camera. This could be do to a wide variety of problems in the 
camera, network or PC. Most often this situation occurs when a firewall allows certain packets (such 
as the discovery packets) but not others (the packets needed for a “connection”).

2.8.6 General Errors
In the status bar at the bottom of the screen there may be an indication that an error has occurred. 
When you position the cursor over the error icon (exclamation mark), the error will be displayed in a 
temporary pop-up. It is possible to view all the error messages by selecting the Tools tab at the top of 
he screen, and then select the Log button to the left.
2.8.7 Unable to View Video Stream
If the video stream from the camera is not displayed in FSM, it could be that the packets are blocked 
by the firewall, or there could be a conflict with video codecs that are installed for other video 
programs.
When displaying video with FSM for the first time, the Windows Personal Firewall may ask for 
permission to allow the FLIR Video Player (vp.exe) to communicate on the network. Select the check 
boxes (domain/private/public) that are appropriate for your network. 
If necessary, test to make sure the video from the camera can be viewed by a generic video player 
such as VLC media player (http://www.videolan.org/vlc/).To view the video stream, specify RTSP port 
554 and the appropriate stream name such as “ch0”. For example:
rtsp://192.168.250.116:554/ch0 
Refer to section 3.8.1 “RTP Settings” on page 3-14 for additional information on RTP and stream 
names.

2.8.8 Noisy image
With the analog video signal, a noisy image is usually attributed to a cable problem (too long or 
inferior quality) or the cable is picking up electromagnetic interference (EMI) from another device. 
Although coax cable has built-in losses, the longer the cable is (or the smaller the wire gauge/
thickness), the more severe the losses become; and the higher the signal frequency, the more 
pronounced the losses. Unfortunately this is one of the most common and unnecessary problems 
that plagues video systems in general.
Cable characteristics are determined by a number of factors (core material, dielectric material and 
shield construction, among others) and must be carefully matched to the specific application. 
Moreover, the transmission characteristics of the cable will be influenced by the physical environment 
through which the cable is run and the method of installation. Use only high quality cable and ensure 
the cable is suitable to the marine environment.
Check cable connector terminations. Inferior quality connections may use multiple adapters which 
can cause unacceptable noise. Use a high-quality video distribution amplifier when splitting the signal 
to multiple monitors.
2.8.9 Image too dark or too light
By default the FC-Series S thermal camera uses an Automatic Gain Control (AGC) setting that has 
proven to be superior for most applications, and the camera will respond to varying conditions 
automatically. The installer should keep in mind that the sky is quite cold and can strongly affect the 
overall image. It may be possible to avoid a problem by slightly moving the camera up or down to 
include (or exclude) items with hot or cold temperatures that influence the overall image. For example, 
a very cold background (such as the sky) could cause the camera to use a wider temperature range 
than appropriate.
There are five Scene Presets that use a combination of settings to produce different configurations 
that could improve the video image for a given set of conditions. The presets can be toggled with the 
Scene Presets button on the Live Video page.
The presets can also be selected from the Scene Presets in the Setup page. Refer to section 3.1 
“Thermal Image Setup” on page 3-1

2.8.10 Eastern or Western Exposure
Once installed, the camera may point directly east or west, and this may cause the sun to be in the 
field of view during certain portions of the day. We do not recommend intentionally viewing the sun, 
but looking at the sun will not permanently damage the sensor. In fact the thermal imaging camera 
often provides a considerable advantage over a conventional camera in this type of back-lit situation. 
However, the sun may introduce image artifacts that will eventually correct out. and it may take some 
time for the camera to recover. The amount of time needed for recovery will depend on how long the 
camera was exposed to the sun. The longer the exposure, the longer the recovery time needed.
