In the Video Streaming menu, can be changed the stream parameters for each video stream. The stream
for configuration is selected by buttons at the top of the page.
Resolution - the resolution of configured video stream. The camera supports three video streams
simultaneously and each can be individually configured. This allows e.g. to set a high-quality stream
for archival video and a second stream in lower quality, to displaying "live" video.
FPS (frames per second) - a maximum of 20fps for 2048x1520 resolution or maximum 25fps for PAL
(30fps for NTSC) for lower resolutions.
Vide o Code Type - a choice of standard encoding the video stream. Available options H264 and H265
Video Code Level - allows to set one of the available profiles ( Baseline , Main Profile , High Profile )
*
Audio - enable/disable audio stream

I Frame Interval - time interval between key frames. For higher bitrates, key frames interval should be
smaller. Smaller frame interval is recommended to increase position accuracy of return video and
advantageous to the network video. If frame interval become small, the video streaming will become
big, but the image quality will become better.
Bitrate Control - there are two types of bit rates: CBR (constant bit rate) and VBR (variable bit rate).
When the VBR is selected, from the drop-down list below you can choose the level of quality of the
video stream (options from Lowest to Best ). If you select CBR , this list does not appear.
Bitrate - allows to select bitrates from a list of available values ( Pre_Defined option), or manually enter
the desired bitrate, from the acceptable range ( User_defined option).
Bitrate parameter has a different function, depending on the option selected in position Bitrate Control :
when the VBR is selected sets the maximum size of the data stream with a variable bit rates, while the
CBR is selected, sets the specific size of the data stream with a constant bit rates.
All of the above options are available for each of the three streams generated by the camera.
