Main
Terminal
Camera 1
1024 kbps/30 fps
H.264/QVGA
When the sum of the network camera bit rates
(1024 kbps + 512 kbps) does not exceed the main PCS's
LAN bandwidth (4 Mbps), cameras 1 and 2 operate using
the network camera setting values.
As shown above, a mixture of different bit rates, frame
rates, modes (H.264 or MPEG4) and image sizes (QVGA
or QQVGA) can be used.
1-b-1
Main
Terminal
Camera 1
2048 kbps/15 fps
When the sum of the network camera bit rates
(2048 kbps + 2048 kbps) exceeds the main PCS's LAN
bandwidth (4 Mbps) due to the connection of camera2
the bit rate is changed to the optimum value for cameras
1 and 2 regardless of the main PCS's network camera
settings.
1-b-2
Main
Terminal
Camera 1
2048 kbps/30 fps
H.264/QVGA
When the sum of the network camera bit rates
(2048 kbps + 2048 kbps) exceeds the main PCS's LAN
bandwidth (4 Mbps) due to the connection of camera 2
the mode changes to "Voice Only" for the terminal
(camera 2) that is exceeding the bandwidth. (Camera 1's
image is displayed.)
*2: If the network camera bit rate is configured as 2048kbps for both cameras 1 and 2, the sum exceeds the 4Mbps of the PCS's LAN
bandwidth because the network camera bit rate does not include audio (G.711 = 64kbps).
