Video Quality Settings For Stream 1 and 2
You can set two streams for the Cisco VC 220 network camera for different
viewing devices. For example, set one stream of the Cisco VC 220 network
camera to a smaller frame size and a lower bit rate for viewing on mobile phones.
Then set the other stream to a larger video size and a higher bit rate for viewing on
web browsers.

NOTE
Apple QuickTime Player supports only HTTP and UDP media streams. If you have
trouble viewing video using a Firefox browser with the QuickTime plug-in, set
Stream 1 and Stream 2 to MJPEG.

Mode—The Cisco VC 220 network camera offers two choices of video
compression standards for real-time viewing: MPEG-4 and MJPEG. If
MPEG-4 is selected, it is streamed in RTP encapsulation over UDP. There
are four dependent parameters provided in MPEG-4 mode for video
performance adjustment.

•
Resolution—The video resolutions are selectable at the following settings:
640x480, 320x240, and 176x144. A larger frame resolution takes up more
bandwidth.

Video quality—A complex scene generally produces larger file size,
meaning that higher bandwidth will be needed for data transmission.
Therefore, if Constant Bit Rate is selected, the bandwidth usage is fixed at
a selected level, resulting in varying video quality performances. The bit
rates are selectable at the following rates: 40Kbps, 50Kbps, 64Kbps,
128Kbps, 256Kbps, 512Kbps, 768Kbps, 1Mbps, 1.5 Mbps, 2Mbps,
3Mbps, and 4Mbps.

If Fixed Quality is selected, all frames are transmitted with the same quality
and bandwidth usage is unpredictable. Select the video quality from the
following choices: Medium, Standard, Good, Detailed, and Excellent.
