Option Description
Streaming Mode Choose the mode that the IP camera uses for video streaming:
• Single MPEG-4 Stream—Configures MPEG-4 for the primary stream.
The stream can be up to D1 resolution and 30 fps for NTSC or 25 fps for
PAL.
• Single MJPEG Stream—Configures MJPEG for the primary stream.
The stream can be up to D1 resolution and 15 fps.
• Dual MPEG-4 Streams—Configures MPEG-4 for the primary stream
and the secondary stream. The primary stream can be up to 4 CIF and 25
fps for NTSC or 20 fps for PAL. The secondary stream can be up to CIF
and 15 fps.
• Dual Streams (MPEG-4 + MJPEG)—Configures MPEG-4 for the
primary stream and MJPEG for the secondary stream. The primary
stream can be up to 4CIF and 25 fps for NTSC or 20 fps for PAL. The
secondary stream can be up to CIF and 15 fps.
MPEG-4 Settings 1
Note These MPEG-4 Settings options appear if you choose Single MPEG-4 Stream, Dual MPEG-4
Streams, or Dual Streams (MPEG-4 + MJPEG) from the Streaming Mode drop-down list.
Resolution Choose the desired video resolution format for the primary video stream
from the IP camera.
For the wired IP camera, the default resolution is 720 x 480 for NTSC or
720
x 576 for PAL. For the wireless IP camera, the default resolution is 4CIF.
Video Quality Control Choose an option for the video quality of the primary video stream from the
IP camera:
• Constant Bit Rate—Specifies that the video stream is output at or close
to the constant bit rate that you choose. The default value for the wired
IP camera is 4 Mbps. The default value for the wireless IP camera is
1
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 Very 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.
