NOTE
Frame rate (frames per second) is determined by the resolution, image data size (bit rate), and transmission
traffic status. The Administrator and
users can check the frame rate status in the FPS Status on the VPort’s web
homepage.
Video Quality Control
Video Quality Control is used to optimize the bandwidth of the video stream. There are 2 modes for video
quality control.
Setting Description Default
Fixed bit rate
(Only for H.264)
The administrator can fix the bandwidth to tune the video
quality and FPS (frames per second) to the optimum
combination.
Different resolutions have
different bandwidth parameters. The
VPort will tune the video performance according to the
bandwidth. A higher bandwidth means better quality.
600Kbps in Full D1
resolution
Fixed Quality The administrator can set the image quality to one of 5
standards: Medium, Standard, Good, Detailed, or Excellent.
The VPort will tune the bandwidth and FPS automatically to the
optimum combination.

NOTE
The image quality, FPS, and bandwidth are influenced significantly by network throughput, system network
bandwidth management, applications the
VPort runs (such as VMD), how complicated the image is, and the
performance of your PC or notebook when displaying images. The administrator should take into consideration
all of these variables when designing the video over IP system, and when specifying the requirements for the
video system.
Camera Control
Four cameras can be connected to the VPort 364A. To setup the PTZ control, administrators need to configure
the parameters of each video channel.
