64 AXIS 223M - Technical Specifications
Frame rates - Motion JPEG and MPEG-4
Typical frame rates in frames/second (fps) for Motion JPEG and MPEG-4 video streams
from the AXIS 223M, specified with the parameter settings listed below. Note that these
values are guidelines only - actual values may vary.
• Normal 4:3 - 9 fps
• Widescreen 16:9 - 12 fps
Motion JPEG settings:
• Viewing in AMC
• Compression level = 30%
MPEG-4 settings:
• Viewing in AMC
• Compression level = 30%
• Video Object Type = Advanced Simple
• GOV length = 8
• GOV structure = IP*
*Note that setting the GOV structure to use “I-frames only” will increase the frame rate at the expense of
the bit rate.
Important!
•The figures displayed here are the values as delivered by the camera. If other restrictions are
currently in force, (e.g. bandwidth limitation) these values might not correspond to those actu-
ally received by the client.
•For Motion JPEG, these values will only be accurate as long as no frame rate limit has been
specified.
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 object type
• MPEG-4 GOV structure
• maximum exposure time
• audio
