There are also factors in the monitored scene that will affect the bandwidth. These are:
• the amount of motion
• the image’s complexity
• the lighting conditions.
For MPEG-4, if there is only limited bandwidth available, and if this is more important
than the image quality, using a constant bit rate (CBR) is recommended. Use a variable bit
rate (VBR) if the image quality needs to be maintained at a higher level. If supported on the
network, consider also using MPEG-4 multicasting, as the bandwidth consumption will be
much lower.
