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 MPEG-4, H.264, and MJPEG files.
• Framerate : Specify the frame rate.
• 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.
As the bit rate can be adjusted limitedly according to the resolution, frame rate and screen
J
`
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.
• GOP size : Select a GOP size between 1 and 150.
• Profile : You can select the H.264 profiling method.
• Entropy coding : Reduce the possible compression loss due to encoding.
• Multicast(VNP) : Specify the use of the VNP protocol.
- IPv4 : Enter an IPv4 address with which you can connect to the IPv4 network.
- Port : Specify the video communication port.
- TTL : Set the TTL for the VNP packet.
• Multicast(RTP) : Specify the use of the RTP protocol.
- IPv4 : Enter an IPv4 address with which you can connect to the IPv4 network.
- Port : Specify the video communication port.
- TTL : You can set the TTL for the RTP packet.
