Inter-Packet Delay

VA GigE camera provides the Inter-packet delay feature to set the delay in ticks between the packets transmitted
by the camera.
Packet Size
The Gev SCPS Packet Size parameter sets the size of the packets that the camera will use when it sends the
data via the selected stream channel. This parameter should always be set to the maximum size that your
network components (Ethernet Adapter) can handle.
Setting the delay between packets
The Gev SCPD parameter sets the delay in ticks between the packets transmitted from the camera. Increasing
the delay will decrease the camera's effective data transmission rate and will thus decrease the network
bandwidth used by the camera.
In the VA GigE camera, one tick is 8 ㎱. To check the tick frequency, read the Gev Time stamp Tick Frequency
parameter value.
In case of multiple cameras or other devices working on the same physical network, it might be desirable to send
the packets of a camera's streaming channel with a certain inter-packet delay in order to allow multiple cameras
or devices to share a given network bandwidth.
