Chapter 3 Configuring and Managing the IP Camera

Audio/Video Windows

To display the Video window, access the configuration windows as described in the “Accessing the IP Camera Windows” section on page 2-6, click, Audio/Video, then click Video.

If you change any options in the Video window, you must click Save to save the changes. To discard the changes, click Cancel before clicking Save. These buttons appear at the bottom of the window. You may need to scroll down to see them.

Table 3-10describes the options in the Video window.

Table 3-10 Video Window Options

Option	Description
Streaming Mode	Choose the mode that the IP camera uses for video streaming:
	• Single MPEG-4Stream—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-4Streams—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)—ConfiguresMPEG-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.
