5.1.4 Video : Configure profile
This device provides 2 modes of video profile. The first one is Mega-pixel mode which
supports video resolution up to Mega-pixel. However the maximum frame rate of this mode
is up to 15fps only. The second one is VGA mode which supports video resolution up to
VGA but frame rate can be up to 30fps. User only can select either Mega-pixel or VGA
mode to operate the camera. Switching Mega-pixel and VGA, the device will take time to
reboot system.
Common
Text Overlay Setting:
There are some important information can be embedded into image, including date, time,
and/or text.
Video Profile:
User can only choose either VGA Multi-profile or Mega Multi-profile mode. VGA Multi-profile
mode can serve H.264, MPEG4, and JPEG streams up to VGA resolution simultaneously.
On the other hand, Mega-pixel mode, in addition to VGA resolution, it can serve
H.264/Mega and JPEG/Mega two more streams simultaneously.
H264
It’s H.264 encoder mode in this profile.
Resolution:
There are four resolutions in this profile: SXGA, VGA, QVGA and QQVGA.
Rate Control:
Defines the rate control method of this profile. There are two options: Constant Bit Rate
(CBR) or Variable Bit Rate (VBR). For CBR, the video bit rate is between low to high
bandwidth based on different resolutions. User can set the desired bit rate to match the
limitation of bandwidth. For VBR, user should choose the quality level to set the video
quality rather than bit rate. The quality level is between 1 and 100. The higher value can
reach the better quality but of course will consume higher bandwidth.
