Use the Camera Control > Video Settings page to set video parameters. When 
you complete the video configuration, click Save to save the settings; otherwise 
click Cancel to discard the changes. 

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.

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.
