•
Frame rate:
MPEG-4 images will be transmitted with the frame rate selected for “Frame rate*”.
•
Best effort:
In accordance with the network bandwidth, MPEG-4 images will be transmitted with the bit
rate varying between the maximum and minimum bit rates that are set for “Max bit rate (per client)*”.
•
Default:
Frame rate
Note
•
When “Frame rate” is set for “Transmission priority”, number of users who can access the camera may
be limited.
[Frame rate*]
Select a frame rate for MPEG-4 images from the following.
1fps/ 3fps/ 5fps*/ 7.5fps*/ 10fps*/ 12fps*/ 15fps*/ 20fps*/ 30fps*
•
Default:
30fps*
Note
•
When “Frame rate” is selected for “Transmission priority”, this setting is available.
•
“Frame rate*” is limited by “Max bit rate (per client)*”. For this reason, the frame rate may be lower than
the specified value when any value marked with an asterisk (*) is selected.
[Max bit rate (per client)*]
Select a MPEG-4 bit rate per a client from the following. When “Best effort” is selected for “Transmission
priority”, set the maximum and minimum bit rates.
64kbps/ 128kbps*/ 256kbps*/ 384kbps*/ 512kbps*/ 768kbps*/ 1024kbps*/ 1536kbps*/ 2048kbps*/ 3072kbps*/
4096kbps*/ Unlimited*
•
Default:
–
MPEG-4(1): 2048kbps*
–
MPEG-4(2): 2048kbps*
* “Unlimited*” is available only when “Frame rate” is selected for “Transmission priority”.
Note
•
The MPEG-4 bit rate is limited by “Bandwidth control(bit rate)” of [Network] tab on the “Network” page
(
®
page 166). For this reason, the bit rate may be lower than the value when any value with an asterisk
(*) on the right is selected.
•
When “Unlimited*” is selected, the number of users who can access MPEG-4 images will be limited to
“1”. (Only a single user can access MPEG-4 images.)
•
It is impossible to select “Unlimited*” for both “MPEG-4(1)” and “MPEG-4(2)”.
[Image quality]
Select the image quality of MPEG-4 images from the following.
Low(Motion priority)/ Normal/ Fine(Image quality priority)
•
Default:
Normal
Note
•
When “Constant bit rate” or “Best effort” is selected for “Transmission priority”, this setting is available.
[Refresh interval]
Select an interval (I-frame interval; 0.2–5 seconds) to refresh the displayed MPEG-4 images.
If using under a network environment with frequent error occurrences, shorten the refresh interval for
MPEG-4 to diminish image distortions. However, the refresh interval may be longer than the set value.
0.2s/ 0.25s/ 0.33s/ 0.5s/ 1s/ 2s/ 3s/ 4s/ 5s

Default:
