[Name] Rename the video stream. To display the name of video stream on
the Live View window, see 6.2.9 Camera Name Display .
[Connection Template] Select the type of your network connection.
Unless you select Customized , this option will automatically bring up the
recommended video resolution, frame rate, bandwidth and GOP size.
[Video Signal Type] The GV-IPCAM H.264 provides three codec options:
MPEG4 , H.264 and MJPEG . And there are several options for selecting
image resolutions: 1280 x 1024 , 640 x 480 , 360 x 240 and 176 x 144 . The
frame rate to transmit images can reach 30 fps for all kinds of resolutions,
except the resolution of 1280 x 1024. The resolution of 1280 x 1024 can
only be applied to Streaming 1.
Most 3GPP mobile phone supports video streaming with MPEG4 video.
Due to the limitation of the bandwidth for 3GPP, only 176 x 144 and 360 x
240 video resolutions will be supported for mobile phone setting. To
change 3GPP port settings, see
7.3.7 3GPP .
[Bandwidth Management] When using H.264 or MPEG4 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 3 standards: Fair , Good , and
Excellent .
„
CBR (Constant Bitrate): CBR is used to achieve a specific bitrate by
varying the quality of the H.264 or MPEG4 stream. Select one of the
bitrates from the drop-down list.
[GOP Structure and Length] Set the maximum number of frames in a
GOP structure (the GOP size limit).
