Video Area
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 primary 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.
Audio Setup Area
Note These options apply to the primary stream only.
Enable Audio		Check this check box if you if you want the IP camera to transmit and receive
		audio.
Audio Compression		Choose the codec (G.711 A-Law, G.711 u-Law, or AAC) for audio that is
		transmitted from the IP camera.
		AAC provides highest quality audio and consumes the least bandwidth.
		The default value is G.711 A-law.
