Select Video Stream to record video stream only. Select Video&Audio to
record both video and audio streams.
Note
: Video&Audio is only available for those camera models that support
audio.
Resolution
: Specifies the recording resolution. A higher image resolution
provides a higher image quality but also requires a higher bit rate. The
resolution options listed depend on the type of camera and on whether main
sub or third stream is being used.
Note
: Resolutions can vary depending on the camera model.
Bitrate Type
: Specifies whether variable or fixed bit rate is used. Variable
produces higher quality results suitable for video downloads and streaming.
Default is Constant.
Video Quality
: Specifies the quality level of the image. It can be set when
variable bit rate is selected. Options include: Lowest, Lower, Medium, Higher
and Highest.
Frame Rate
: Specifies the frame rate for the selected resolution.
The frame rate is the number of video frames that are shown or sent per
second.
Note
: The maximum frame rate depends on the camera model and selected
resolution. Please check the camera specifications in its datasheet.
Max bit rate
: Specifies the maximum allowed bit rate. A high image
resolution requires that a high bit rate must also be selected.
Video Encoding
: Specifies the video encoder used.
Profile
