To do this, special format strings are added as part
of a text overlay. Simply add #r (average frame
rate in fps) and/or #b (average bandwidth in kbps)
to the overlay.
For detailed instructions, please see the online help
for Video & Image > Overlay Settings, and the
help for File Naming & Date/Time Formats.
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 actually received by the client.
For Motion JPEG, these values are accurate as long as no frame rate limit has been specified.
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 210A/211A.
Note that these values are guidelines only - actual values may vary.
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:
Setting the GOV structure to use "I-frames only" will increase the frame rate at the expense of the bit rate.
* The GOV structure can take two different forms; I and IP. The I-structure sends complete images
(I-images) whereas the IP-structure mostly sends the differences compared with the previous image
(P-images) and only a few I-images. The IP-structure requires much less bandwidth than the I-structure.
