Network Related Camera Parameters and Managing Bandwidth
Note
If you increase the inter-packet delay to lower a camera's data output rate
there is something that you must keep in mind. When you lower the data
output rate, you increase the amount of time that the camera needs to transmit
an acquired frame (image). Increasing the frame transmission time can restrict
the camera's maximum allowed acquisition frame rate.
Step 6 - Check that the total bandwidth assigned is less than the network capacity.
1. For each camera, determine the current value of the Bandwidth Assigned parameter. The
value is in Byte/s. (Make sure that you determine the value of the Bandwidth Assigned param-
eter after you have made any adjustments described in the earlier steps.)
2. Find the sum of the current Bandwidth Assigned parameter values for all of the cameras.
If the sum of the Bandwidth Assigned values is less than 125 MByte/s for a Give network or 12.5
M/Byte/s for a 100 Bit/s network, the bandwidth management is OK.
If the sum of the Bandwidth Assigned values is greater than 125 MByte/s for a Give network or 12.5
M/Byte/s for a 100 Bit/s network, the cameras need more bandwidth than is available and you must
make adjustments. In essence, you must lower the data bandwidth needed by one or more of the
cameras and then adjust the data bandwidths assigned so that they reflect the lower bandwidth
needs.
You can lower the data bandwidth needed by a camera either by lowering its frame rate or by
decreasing the size of the area of interest (AOI). Once you have adjusted the frame rates and/or
AOI settings on the cameras, you should repeat steps 2 through 6.
For more information about the camera's maximum allowed frame transmission rate, see
Section 10.9 on page 137.
For more information about the AOI, see Section 13.5 on
96
page 185.
