10.2.6 Interrupt Moderation rate
If the Network Connection Properties list contains
a property called Interrupt Moderation Rate, then
it is possible to set the preferred value. When it is
changed from Minimal, to Medium, High and
Extreme, the number of interruptions is
decreased to get better performance. Set it to
“Extreme“.
Click “OK” to save the property.
10.2.7 Calculating and setting Inter-Packet Delay
When connecting several cameras to one network interface card via a switching hub, it is
important to optimize the Inter-Packet Delay of the cameras to avoid congestion in the switch.
A sure sign of congestion is the loss of packets.
Since increasing the inter-packet delay also adds overhead to the data transfer it is important
to calculate the optimal setting in order to make best use of the video bandwidth.
JAI Control Tool has a built in wizard for calculating Inter-Packet Delay.
When the Inter-Packet Delay function is activated, a button appears on the right hand side of
the bar.
Click the button to open the calculation wizard window.
