Advanced Configuration
3.1.2 Video Page
By default, two video streams are enabled for the camera: Video 0 and Video 1. Both video streams
are available for viewing from a client program such as FLIR Latitude, a stand-alone video player, or
a third-party VMS (including ONVIF systems).
By default, Video 0 uses MJPEG encoding and Video 1 uses H.264 encoding. To modify parameters
that affect a particular IP Video stream from the camera, select the appropriate link (for example,
Video - 0).
With the factory configuration, the default parameters provide high-quality full frame-rate video
streams with reasonable bandwidth usage. 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.
After making adjustments, scroll down to save the changes through power cycles.
Caution!
Encoding: The parameters in the Encoding section will
have a significant impact on the quality and bandwidth
requirements of the video stream. In general it is
recommended that the default values are used initially, and
then individual parameters can be modified and tested
incrementally to determine if the bandwidth and quality
requirements are met.
For the video streams, the Codec options are MPEG4
RTSP, H.264 or MJPEG. MPEG4 RTSP requires the least
amount of processing, and MJPEG requires the most.
The Bit Rate parameter is only used when the Rate Control
parameter is set to CBR (Constant Bit Rate). With the CBR setting, the system attempts to keep the
video at or near the target bit rate.
Adjustments to these settings should only be made by someone trained with thermal cameras
and a thorough understanding of how the various settings affect the image.
Haphazard changes can lead to image problems including a complete loss of video.
