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 analog cameras connected to the video server

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.
