Chapter 3 Configuring and Managing the IP Camera
Feature Setup Windows
Enable Multicast Check this check box to send video and audio data as a multicast stream.
When multicast is enabled, the IP camera sends video and audio to the
multicast addresses that you designate. Multicast enables several devices to
receive the video signal from the IP camera simultaneously.
Multicast Address Enter the multicast IP address on which the IP camera sends a multicast
audio/video stream.
Multicast Video Port Enter the port on which the IP camera sends a multicast video stream.
Valid values are even numbers 1024 through 65532.
Multicast Audio Port Enter the port on which the IP camera sends a multicast audio stream.
Valid values are even numbers 1024 through 65532.
Time to Live Enter the number of hops, which specifies the number of network devices
that an audio/video stream can pass before arriving at its destination or being
dropped.
Valid values are 1 through 255.
Video Area
Note Each video stream uses its own set of video options. The settings shown in the Video Area
apply to the currently selected stream only.
Video Standard Choose the system for video transmission: NTSC or PAL.
The setting that you make affects each channel that is enabled.
Video Codec Display only: Shows the codec for video transmission: H.264 for the primary
stream and MJPEG for the secondary stream.
Video Resolution 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
Table 4-1.
Maximum Frame Rate Choose the maximum frame rate of the video stream.
Video Quality 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.
