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.
58 – 10x Network Mini Smart Dome Camera
❖
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.
