Compression
When it is necessary to adjust a smooth transmission status according to network
situations, users can increase the compressibility to carry out the network transmission
stably. On the other hand, when it is necessary to maintain a detailed monitoring screen
by enhancing the image quality, users can do so by decreasing the compressibility. In
ease case, please adjust this function according to the network status and monitoring
purposes. The default is 2000(Kbps).

BCS Adjust
Brightness
The screen brightness can be adjusted from 0 to 255 stages, and the default is 128. The
brightness may differ depending on the equipment and PC monitor status.
Contrast
The screen contrast can be adjusted from 0 to 127 stages, and the
default is 73.
The contrast may differ depending on the equipment and PC monitor status.
Saturation
The screen saturation can be adjusted from 0 to 127 stages, and the
default is 64.
The saturation may differ depending on the equipment and PC monitor status.

MPEG4 Video Stream
Frame rate
Upon the real-time play, users should select a frame refresh rate per second. If the rate is
high, the image will become smooth. On the other hand, if the rate is low, the image will
not be natural but it can reduce a network load.
Bit-rate control
Variable bit rate (VBR) : It refers to the type of using a variable bit rate (VBR). Increase a
bit rate for the image with much motion, and decrease a bit rate for the image with little
motion. The basic setting value is a VBR type.
Constant bit rate (CBR) : Using a constant bit rate (CBR) may guarantee a stable play.
However, if a large amount of data is not required, it may cause the waste of a
transmission rate. If a large amount of data is required, it may cause the image quality to
be decreased.
Profile
SP (Simple Profile) is available up to the CIF resolution and 384kbit/s.
ASP (Advanced Simple Profile) is available up to the 4CIF resolution and 8000kbit/s.
GOV size
Enter the GOV (group of VOP) size. If users want to have a high quality of fast image one
by one, please decrease the value. For the purpose of general monitoring, please do not
change a basic value. Such act may cause a problem to the system performance. For the
details of GOV setting, please contact the service center.
