Description
Check this check box to send video data as a multicast stream.
When multicast is enabled, the IP camera sends video to the multicast
addresses that you designate. Multicast enables several devices to receive the
video signal from the IP camera simultaneously.
Enter the multicast IP address on which the IP camera sends a multicast
video stream.
Enter the port on which the IP camera sends a multicast video stream.
Valid values are even numbers 1024 through 65532.
Enter the port on which the IP camera sends a multicast audio stream.
Valid values are even numbers 1024 through 65532.
Note Audio is not supported in this release.
Enter the number of hops, which specifies the number of network devices
that an video stream can pass before arriving at its destination or being
dropped.
Valid values are 1 through 255.
Each video stream uses its own set of video options. The settings shown in the Video Area
apply to the currently selected stream only.
Choose the system for video transmission: NTSC or PAL.
The setting that you make affects each channel that is enabled.
Display only: Shows the codec for video transmission: H.264 for the primary
stream and MJPEG for the secondary stream.
Choose the resolution for video transmission. The resolutions in this
drop-down list depend on the video standard that you selected.
You can also change the resolution for video transmission by using the Video
Resolution drop-down list in the Camera Video & Control window, as
described in
Choose the maximum frame rate of the video stream.
Choose an option for the video quality of the video stream from the IP
camera:
Constant Bit Rate—Available for the primary stream only. Specifies
•
that the video stream is output at or close to the constant bit rate that you
choose. The default value is 4 Mbps. A higher bit rate provides better
video quality but consumes more bandwidth.
• Fixed Quality—Specifies that video is output at a fixed quality, which
ranges from Very High to Low. The bit rate may vary to maintain this
quality. The default fixed quality is Normal. A higher fixed quality
provides better video quality but consumes more bandwidth.
You can use these options to help manage bandwidth use in your network.
For example, if the IP camera is focused on an area with little movement,
such as an emergency exit, you can configure it with a low fixed quality.
