MPEG4 NETWORK IP CAMERA User’s Guide

Quality
: Set the quality of encoding images. Lower is the number higher is the quality. This option is
available when user selects the VBR rate control. Note that to achieve the set quality, the maximum bit
rate can be used in VBR mode. Thus, the higher the set quality is, the more bandwidth usage on network.
Bit rate:
Set the target bit rate of encoding video. This option is available in CBR mode only. You can set
the bit rate values from 30 kbps up to 5100 kbps at the interval of 30 kbps. The higher bit rate assures
higher quality of live video but on the expense of the more network bandwidth usage. Controlling the
maximum bit rate is the good idea for controlling the bandwidth used by Mpeg4 video stream.
As the bit rate is fixed, the frame rate and image quality can be affected adversely. That is, the frame rate
and image quality are traded off when the bit rate is fixed.
Resolution
Select the resolution for output video. Mpeg4 network IP camera support two type of image resolution,
D1[720x480] & CIF[352x240].
Frame rate
:
Select frame rate according to the choice. The higher value of frame rate assures smoother video. But the
more fps needs the more network-bandwidth.
GOP
Set the size of GOP (Group of Pictures). MPEG4 video stream consist continuous GOP and one GOP
consists of one I frame and P frames. This value equals to the period of I frame. The more GOP size is
given the little network-bandwidth will be occupied. Setting high value of GOP will save considerable
network bandwidth.
Display Name/Location Stamp
:
Select ‘On’ if you want to display camera name & location on the top of the transmitted images.
Display Time/Date Stamp :
Select ‘On’ if you want to display the camera time & date on the top of the transmitted images.
Brightness
Set the image brightness. The higher number means brighter image. (Input digits from 0 to 255)
De-Interlace
Select this filter if you want to monitor a de-interlaced video (a sequence of frame). The Mpeg4 Network
