Performance optimization
The video data from the camera is (like all other data in the network) transferred
in packets. The default value for this packet size is 1440 bytes. In some cases it
can be an advantage to increase this packet size because then fewer packets are
needed to transfer the image data. This results in less overhead and better per-
formance. But these oversized packets are not standardized so not every net-
work card / device supports it. To determine if your network card supports it fol-
low these steps:
1. Open the device manager
2. Open the properties of the network card. Try to find a value called Jumbo
Frames, Jumbo Packets or Packet Size and change it to the maximum,
e.g. 9014 Bytes.
If the camera is not connected directly to the PC but over a switched network, it
is important to know that also the switches must support jumbo frames.
The following illustration shows an example for a network with several
switches. The maximum packet size between the PC and the camera in this
example is 4088 bytes.
Refer to the technical data of the switches to determine if Jumbo Frames are
supported.
If you have determined the maximum size of a packet you can modify the used
packet size in your application.

The maximum packet size the iPORT protocol can use is 8128
bytes.
