Video Stream Parameters
From the Maintenance menu, it is
possible to modify the video stream
parameters by selecting the Sensor >
Modules > Video page. Various
parameters that affect both image
quality and transmission bandwidth
are available.
The number of video streams that are
available will depend on the camera
model in use. Generally there will be
two or more streams for each video
source (thermal or daylight camera),
and typically the second of the two
video streams is used by the Live
Video web page.
For specific configuration information
about a particular camera model, refer
to the manual provided with the
camera.
On the PT-Series and D-Series cameras, the first two video streams (Video 0 and Video 1)
correspond to the thermal camera, and the other streams (Video 2 and Video 3) correspond to the
daylight camera (or the second thermal camera, when available).'
On the FC-Series camera, three video streams are enabled for the thermal (IR) camera: Video 0,
Video 1, and Video 3. The Video 3 stream is used by the web browser Live Video display. The Video
0 and Video 1 streams are available for viewing from a client program such as FSM, a stand-alone
video player, or a third-party VMS.
To modify parameters that affect a particular IP Video stream from the camera, select the appropriate
link at the top (for example, Video 0). For a video stream that is used by the Live Video web page, it is
only possible to change the frame rate and image size.
The default settings for each video stream generally provide high-quality, full frame-rate video. In
general, for most installations it will not be necessary to modify the default parameters. However in
some cases, such as when a video stream is sent over a wireless network, it may be useful to "tune"
the video stream to try to reduce the bandwidth requirements. In particular, the RTP Settings,
Network Options and the Settings parameters are described below.
There are some challenges with streaming video over an IP network, when compared to other
traditional IP applications which are less time-critical, such as email and web browsing. In particular,
there are requirements which must be fulfilled to ensure satisfactory video quality in professional
security environments. There are many parameters and factors related to network infrastructure,
protocols, codecs and so on that can affect the quality and bit rate of a video stream when it is
established between the camera and a client.
On some cameras it may be possible to add an additional video stream by selecting the "+" link;
however this is not recommended. Turning on additional video stream could place a higher load on
the microprocessor and could lead to poor performance overall if not done properly. If you have
problems or questions, contact your local FLIR representative or FLIR Technical Support.
