VS3102 uses MPEG4 codec compression for best streaming solution. The compressed video
data is far less than JPEG in normal cases but it still depends on the level of difference between
every two sequential images. There are three dependent parameters provided for adjustment.
" Maximum Frame Rate " limits the maximal refresh frame rate that can be combined with the
" Video Quality Control " to optimize the bandwidth utilization and video quality. If users want
to fix the bandwidth utilization regardless of the video quality, choose "Fix Bit Rate" and select
the desired bandwidth. The video quality may be poor in order to send maximal frames within
the limited bandwidth when images change drastically. Consequently to ensure the video
quantization rate regardless of the bandwidth, it will utilize more bandwidth to send the maximal
frames when images change drastically.
The option " Enable Motion Detection " will control the event of motion detection on the
application page. If this option is enabled, the preset windows framed by red lines will appear in
the video window even if no option is checked on the application page. If this option is disabled,
then any settings related to motion detection will have no effect. Motion detection will increase
system load. Enter the motion detection option page for advanced configuration.
To adjust video from external cameras, use " Flip " to map the video vertically and " Mirror " to
map the video horizontally.
