Network Related Camera
Parameters and Managing
Bandwidth
This section describes the camera parameters that are related to the camera’s performance on the
network. It also describes how to use the parameters to manage the available network bandwidth
when you are using multiple cameras.
B.1 Network Related
Parameters in the Camera
The camera includes several parameters that determine how it will use its network connection to
transmit data to the host PC. The list below describes each parameter and provides basic
information about how the parameter is used. The following section describes how you can use the
parameters to manage the bandwidth used by each camera on your network.
Payload Size (read only)
Indicates the total size in bytes of the image data plus any chunk data (if chunks are enabled) that
the camera will transmit. Packet headers are not included.
Stream Channel Selector (read/write)
The GigE Vision standard specifies a mechanism for establishing several separate stream channels
between the camera and the PC. This parameter selects the stream channel that will be affected
when the other network related parameters are changed.
Currently, the cameras support only one stream channel, i.e., stream channel 0.
Packet Size (read/write)
As specified in the GigE Vision standard, each acquired image will be fit into a data block. The block
contains three elements: a data leader consisting of one packet used to signal the beginning of a
data block, the data payload consisting of one or more packets containing the actual data for the
current block, and a data trailer consisting of one packet used to signal the end of the data block.
The packet size parameter sets the size of the packets that the camera will use when it sends the
data payload via the selected stream channel. The value is in bytes. The value does not affect the
