15.3 Configure the settings relating to the priority stream [System]
Click the [System] tab on the “User mng.” page. (→9.1 How to display the setup menu, 9.2 How to operate the setup menu)
The description below is the configuration of the priority stream that can transmit images without deteriorating the image quality and refresh interval even when multiple users access concurrently.
Priority stream
[Activation]
Select “On” or “Off” to determine whether or not to use the priority stream.
•
Default: Off
Note
•
When “On” is selected for “Activation” of “Priority stream”, number of users who can access the camera may be limited.
[Destination IP address(1)]
Enter the first destination IP address.
[Destination IP address(2)]
Enter the second destination IP address.
[Stream type]
Select either “JPEG”, “H.264(1)” or “H.264(2)”.
•
JPEG: JPEG images will be transmitted.
•
H.264(1): H.264(1) images will be transmitted.
•
H.264(2): H.264(2) images will be transmitted.
•
Default: JPEG
Note
•
When “H.264(1)” is selected with “Recording format” of the SD memory card, because “H.264(1)” images are not transferred, images are not transmitted with priority stream.
In the same manner, when “H.264(2)” is selected with “Recording format” of the SD memory card, because “H.264(2)” images are not transferred, images are not transmitted with priority stream.
•
When “Best effort” is selected for “Transmission priority” of “H.264”, bit rate will vary between the maximum and minimum rates while images are being transmitted.
[Refresh interval*]
Select the refresh interval from the following.
This setting is validated only when “JPEG” is selected for “Stream type”.
0.1fps/ 0.2fps/ 0.33fps/ 0.5fps/ 1fps/ 2fps/ 3fps/ 5fps/ 6fps*/ 10fps*/ 12fps*/ 15fps*/ 30fps*
•
Default: 1fps
Note
•
When “On” is selected for “H.264 transmission”, the transmission interval may be longer than the set value when any value with an asterisk (*) on the right is selected.
[Image capture size]
Select the image capture size from the following.
When “2 mega pixel [16:9]” is selected for “Image capture mode”
1920x1080/640x360/320x180
When “1.3 mega pixel [16:9]” is selected for “Image capture mode”
1280x720/640x360/320x180
When “1.3 mega pixel [4:3]” is selected for “Image capture mode”
1280x960/VGA/QVGA
•
Default: 1920x1080
Note
•
When “3 mega pixel [4:3]” is selected for “Image capture mode”, “Priority stream” cannot be used.
