3 Advanced Configuration
Note, the image size for FC-Series cameras with 320 resolution is expanded to be equivalent to the
image size for 640 cameras.
As a rule of thumb, if the video will be viewed on its own and on a reasonably large screen, a large
image size setting may look better. On the other hand, if the video is shown as a tile in a video wall, a
smaller image size may look as good and consume less bandwidth.
MJPEG Codec Type
The video stream for the Live Video web page uses the MJPEG codec type. With this codec type, it
possible to change the qFactor, Image Size and Frame Rate parameters. The qFactor parameter
provides a relative balance of quality and bandwidth, similar to a percentage (25=low quality/
bandwidth - 75=high quality/bandwidth).
