There are 4 options for selecting image resolutions.
NTSC
704 x 480
704 x 480 de-interlace
352 x 240
176 x112
Several frame rates are available.
Format Frame Rate
NTSC 1, 2, 3, 5, 7.5, 10, 15, 30
PAL 1, 2.5, 5, 8, 12.5, 25
Note:
1. The GV-VS11 supports dual streams. By default, the GV-VS11 is in single stream.
2. For GV-VS11, four resolution options and three codec types are available for both
streaming 1 and 2.
3. The frame rate and the performance may vary depending on the number of
connections and data bitrates (different scenes).
[Bandwidth Management]
When using MPEG-4 or H.264, it is possible to control the bitrate, which in turn allows the
amount of bandwidth usage to be controlled.
VBR (Variable Bitrate): The quality of the video stream is kept as constant as
possible at the cost of a varying bitrate. The bandwidth is much more efficiently used
than a comparable CBR.
Set the image quality to one of the 5 standards: Poor, Fair, Good, Great and
Excellent.
CBR (Constant Bitrate): CBR is used to achieve a specific bitrate by varying the
quality of the stream. The bitrates available for selection depend on the image
resolution.
