4.2 GigE Vision
4.2.1 Network (TCP/IP)
Address Assignment
By default, the camera does not have a persistent IP address.
When forcing an IP address by using the PC internal network dialog, changes are
only valid until the next restart of the Camera.
For a peer-to-peer connection of a GigE camera to a PC a network address assign-
ment based on LLA (Local Link Address) is recommended. This involves a net-
work mask “255.255.0.0” as well as a fixed preamble “169.254.xxx.xxx” of the
network address range. A GigE camera will fall back to LLA when no DHCP
server is available and no fixed network address was assigned to the camera.

Jumbo frames
The transport efficiency in the streaming channel can be improved by using
“jumbo frames”. This will reduce overhead caused by maintaining header data
upon each data packet sent. Jumbo frames increase the data size per Ethernet
packet.

INFO Higher packet sizes require network cards that support jumbo packets.
Lost packets
In accordance with the TCP protocol, lost or corrupted packets will be resent.
NOTICE Resends result in higher consumption of bandwidths and will lead to drop
frames. High quality cables prevent resends.
Connecting multiple cameras
Multiple GigE cameras can be connected to a PC either via a switch or using dual
or quad port network interface connectors (NIC).
