Option		Description
Streaming Mode		Choose the mode that the IP camera uses for video streaming:
		• Single H.264 Stream—Configures H.264 for the primary stream. The
		stream can be up to D1 resolution and 30 fps.
		• 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 30 fps.
		• Dual H.264 Streams—Configures H.264 for the primary stream and the
		secondary stream. The primary stream can be up to 4 CIF and 30 fps for
		NTSC or 25 fps for PAL. The secondary stream can be up to CIF 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 30
		fps for NTSC or 25 fps for PAL. The secondary stream can be up to CIF
		and 15 fps.
		• Dual Streams (H.264 + MJPEG)—Configures H.264 for the primary
		stream and MJPEG for the secondary stream. The primary stream can be
		up to 4CIF and 30 fps for NTSC or 25 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 30 fps for NTSC or 25 fps for PAL. The
		secondary stream can be up to CIF and 15 fps.
H.264 Settings 1

Note These H.264 Settings options appear if you choose Single H.264 Stream, Dual H.264 Streams, or Dual Streams (H.264 + MJPEG) from the Streaming Mode drop-down list.

	Resolution	Choose the desired video resolution format for the primary video stream
		from the IP camera.
		The default resolution is 720 x 480 for NTSC or 720 x 576 for PAL.
	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 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 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.
