Bandwidth
As there are many factors that affect bandwidth, it is very difficult to predict the required amounts. The settings
that affect bandwidth are:
• image resolution
• image compression
•frame rate
• MPEG-4 GOV settings
• bit rate control settings
• audio settings
There are also factors in the monitored scene that will affect the bandwidth. These are:
• amount of motion
• image complexity
• 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.
