3.3.3. „Video Streaming” Menu
This tab allows to modify the settings of camera streams.
In the Video Streaming settings menu you can change the parameters for each of the available video
streams. The stream to configure is selected using the buttons at the top of the page.
Resolution - the resolution of configured video stream. Each of the video streams available in the
camera 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) - select the number of frames per second from the available range
Video 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)
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. If you select CBR, this list does not appear.
Bitrate Mode - allows to select bitrates from a list of available values (Predefined option), or manually
enter the desired bitrate, from the available 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.
Audio - enables or disables audio stream encoding.
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
bigger, but the image quality will become better.
