AXIS 231D+/232D+ - Technical Specifications
Frame rates - MPEG-4
The following test results show the frame rates in frames/second (fps) for MPEG-4 streams
from the AXIS 231D+/232D+. Note that these values are guidelines only - actual values
may vary.
The MPEG-4 test conditions:
• Compression level = 50%
•
Video Object Type = Advanced Simple
• GOV structure = IP*
*Note that setting the GOV structure to use “I-frames only” will increase the frame rate.
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
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.
