Troubleshooting Tips
If help is needed during the installation process, contact a local FLIR representative. FLIR Systems,
Inc. offers a selection of training courses to help get the best performance and value from the thermal
imaging camera.

No video:
Check the video connection at the camera and at the 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.
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).
Performance varies with time of day:
It may be possible to 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
higher-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.
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. Confirm that the IP
address for the PC is on the same network as the camera.
By default the camera will broadcast a discovery packet two times per second. Use the FLIR Discovery
Network Assistant (DNA)
or
a packet sniffer utility such as Wireshark and confirm the packets are
being received by the PC from the camera.
Determine if Windows Personal Firewall is blocking the packets. Turn off the firewall or add an
exception for the client program. Typically when a program runs for the first time, a pop-up notification
may ask for permission to communicate on the network. Select the check boxes (domain/private/
public) that are appropriate for the network.
Image too dark or too light:
By default the F-Series 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.
