to add a video profile
You can add as many codecs as necessary so that a variety of profiles can be applied
according to the recording condition.
1. Select a profile number.
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.
• Resolution : Set the video size of the H.264 and MJPEG files.
• Framerate : Specify the frame rate.
M
`
The < Sensor > mode setup in Camera Setup changes the maximum configurable framerate.
Sensor 25 fps 30 fps
Framerate 1~25 fps 1~30 fps
• Compression : Specify the compression rate of the video.
• Bitrate control : You can select one from constant bit rate and variable bit rate for
compression. Constant bit rate (CBR) varies the video quality and fixes network
transfer bit rate, while variable bit rate emphasizes the quality by varying network
transfer bit rate.
• Maximum bitrate : Specify the maximum bit rate of the video. It can be set when
MJPEG is selected.
J `
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.
`
In the case of multiple connections, the maximum/target total beat rate to receive the
video/audio signal stably is 20Mbps.
For example, if 10 users are connected, the maximum/target beat rate must be set to
2Mbps(2048kbps) or less.
• Target bitrate : Specify the bit rate at which you will transfer the video.
• Encoding priority : You can set the video transfer method to Framerate or
Compression.
• GOV length : It specifies the distance (in terms of number of frames) between two
consecutive I-Frames in a video sequence when H.264 codec was selected. (One
I-Frame + 0~Several P-Frames)
