AXIS 231D+/232D+ - Technical Specifications

Frame rates - Motion JPEG

The following test results show the frame rates in frames/second (fps) for Motion JPEG
streams from the AXIS 231D+/232D+, using a compression level of 50%. Note that these
values are guidelines only - actual values may vary.

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
