to add/change the video profile
The profile setup can be added or modified to accommodate various profiles depending on
the recording conditions.
1. Select one from the < video profile > options.
2. Provide the name and select a codec.
3. Specify the conditions under which the codec will be applied.
4. Specify the details of the selected codec including resolution and frame rate.
Click < advanced > to display the context menu.
• Resolution : Set the video size of the H.264 and MJPEG files.
• Framerate : Set the max number of video frames per sec.
M
`
The < Sensor > mode setup in Camera Setup changes the maximum configurable framerate.
Sensor 25 fps 30 fps 50 fps 60 fps
Framerate 1~25 fps 1~30 fps 1~50 fps 1~60 fps
• Compression : Specify the compression rate of the video.
• Maximum bitrate : Set the max bit rate of video when the bit rate control is set to
VBR.

` As the bit rate can be adjusted limitedly according to the resolution, frame rate and screen
complexity, the actual bit rate can be greater than the maximum bit rate. So you must
consider the use conditions when setting the value.
• Target bitrate : Set the target bit rate when the bit rate control is set to CBR.
• Bitrate control : You can select one from constant bit rate and variable bit rate for
compression. Fixed bitrate means that the network transmission bitrate is fixed
while varying the video quality or frame rate, variable bitrate means that a higher
priority is placed on the video quality while varying the bitrate.

`
After setting the fixed bit rate for bit control, if you select the video quality priority mode,
depending on the complexity of the screen, the actual transmitted frame rate may differ from
the frame rate setup in order to guarantee the optimal video quality for the given bit rate.
