AXIS 212 PTZ - Technical Specifications

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.
