Bit Rate
Set the target bit rate of the encoding video. This option is available in CBR mode only. You can set
the bit rate values from 30 kbps up to 9000 kbps at an interval of 300 kbps. A higher bit rate ensures
higher quality of the live video at the expense of more network bandwidth usage. Controlling the
maximum bit rate is good for controlling the bandwidth used by the MPEG4 video stream. As the bit
rate is fixed, the frame rate and image quality can be affected adversely. The image quality can be
reduced if complex image material requires more bandwidth than allowed by the bit rate settings.
Lowest Bit Rate/Quality -> smallest network bandwidth usage
Above image illustrates the effects of lowering the video quality. You have full control over the amount
of bandwidth the camera can use, to the point where it becomes difficult to identify any objects in the
image due to heavy compression damage.
The effects of compression are minimal at the best image quality settings. The bandwidth usage of the
camera at this setting can be up to 8 Mbps.
Resolution
Select the resolution for output video. Pro Series CCD Network Cameras support three types of image
resolution. NTSC: D1 (720x480), VGA (640x480) and CIF (352x240); PAL: D1 (720x576), VGA
(640x576) and CIF (352x288). The Digital PTZ CMOS camera supports 720x480, 640x480, 352x240
and 320x240 pixel image resolution.
