Bandwidth
As there are many factors affecting bandwidth, it is very difficult to predict the required amounts. The
settings that affect bandwidth are:
• the image resolution
• the image compression
•the frame rate
• the MPEG-4 object type
• the MPEG-4 GOV structure
• the audio settings
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.
