This section is provided to familiarize the user with the 
setup tools. Intuitive options are not explained in detail.
All the changes on Setup Tools take effect immediately. 
These settings will be global, affecting the view of all 
users currently logged on.
All settings are always saved in the Network Smart Dome 
Camera even when you close the viewer program or you 
turn off the Power of the Network Smart Dome Camera.
VIDEO & AUDIO 
CONFIGURATION
Image Control
You can adjust the brightness and contrast from 1 
to 100.
Resolution
Select a video size from D1, VGA and CIF. 
NTSC : D1(720x480), VGA(640x480), CIF(352x240)
PAL : D1(720x576), VGA(640x480), CIF(352x288)
Image Quality
Select a video quality level between 1 and 10.
Frame Rate
Select a frame rate.
NTSC : 30fps, 15fps, 8fps, 3fps, 1fps
PAL : 25fps, 13fps, 6fps, 3fps, 1fps
Target Bitrate
Adjust it from 1 to 10 according to the network 
environment. If you select 10, the video quality is 
much improved, but the network connection may 
be lost depending on the network environment, as 
your setting will increase network traffi c.
Compression
Set the compression ratio of an image in MPEG4 
format. Adjust it from 5 to 100, where closing to 
100 will increase the compression ratio.
GOP Size
You can select a GOP size between 1 and 15.
The default is 15, and if set to 15, one I-Frame will 
be output per 15 frames as one I-Frame and 14 
P-Frames constitute the GOP.
The lower the GOP size is, the better the quality 
is; however, the bitrate as well as the data size will 
increase, causing a lower of the fps.
De-Interlace
You will view a sharper image when controlling the 
PTZ operation of a camera.
Input Gain
Select the audio amplifi cation level between 0 and 
10.
(* You will not be able to hear the audio data if the 
audio input gain is at zero.)
Output Gain
Adjust the audio output amplifi cation strength from 
0 and 10.
What is GOP?
GOP(Group of Pictures) is a collection of video frames 
between the initial I-Frame (key frame) and the next 
I-Frame for MPEG4 video compression.
GOP contains three types of frames: I-Frame, 
P-Frame, B-Frame.
(SNC-C6225, C7225 uses only I-Frame and P-Frame.)
I-Frame is the default frame for video compression, 
also known as key frame, which contains one 
complete frame of an image.
P-Frame is a frame that contains data of only 
changes (removed portion) to the I-Frame.
