WARNING - EAR Controlled Technical Data
Configuration
Performance of thermal sensor varies with time of day
There may be differences in the way the thermal sensor performs at different times of the day, due to
the diurnal cycle of the sun. Recall that the thermal sensor produces an image based on
temperature differences.
At certain times of the day, such as just before dawn, the object
s in the scene may all be roughly the
same temperature. Compare this to imagery right after sunset, when objects in the scene may be
radiating heat energy that has been absorbed during the day due to solar loading. Greater
temperature differences in the scene will allow the thermal sensor to produce high-contrast imagery.
Performance may also be affected w
hen 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 thermal sensor to detect the temperature of the object itself, rather than of
the water coating.
Unable To Communicate Over Ethernet
First check to ensure the physical connections are intact and th
at the camera is powered on and
providing analog video to the monitor.
By default the camera will broadc
ast 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.
Unable to View Video Stream
If the video stream from the camera is
not displayed, 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 a VMS for the first time, the Windows Pe
rsonal Firewall may ask for
permission to allow the video player to communicate on the network. Select the check boxes
(domain/private/public) that are appropriate for the network.
If necessary, test to ma
ke 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. For example:
rtsp://192.168.0.250:554/stream1 for
Visible 1,
rtsp://192.168.0.250:554/stream2 for
Visible 2, and 
rtsp://192.168.0.250:554/stream3 for
Thermal/Unified
Authentication is required when lo
gging into the camera stream using any of the user/passwords
setup by an administrator (admin level login). Refer to Users Page.
Refer to Network Options for additional information on RTP settings and stream names.
