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.
