Troubleshooting Tips

If help is needed during the installation process, contact your local FLIR representative. 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.

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.
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: 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.
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.
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.
