AXIS 216FD - Technical Specifications
Frame rates - Motion JPEG and MPEG-4
The following table show typical frame rates in frames/second (fps) for Motion JPEG and
MPEG-4 video streams from the AXIS 216FD.
Note that these values are guidelines only - actual values may vary.
Motion JPEG settings:
Frame rates
Motion JPEG MPEG-4
640x480 30 30
480x360 30 30
320x240 30 30
160x120 30 30
• Viewing in AMC
• Compression level = 30%
MPEG-4 settings:
• Viewing in AMC
• Compression level = 30%
• GOV length = 132
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
There are also factors in the monitored scene that will affect the bandwidth. These are:
• amount of motion
• image’s 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.
