In a network with a DHCP server the camera will obtain its IP address automatically
and the settings shown in the screenshot above will be on “Obtain an IP address au-
tomatically.

Network address assignment
The main components of a network address are the IP (Internet Protocol) address and
the network mask. The usually applied network mask “255.255.255.0” for small net-
works up to 254 PCs represents a 32 Bit long bit mask where the first 24 bits are set
to 1 and the last 8 bits are set to 0. This network mask instructs the network hard-
ware to let those devices exchange information with each other where the first 24 bits
of the IP addresses match for all devices.
Thus the variable range of addresses is made from all possible combinations of the
last 8 bits for which the network mask is set to 0. Exceptions are the first address 0
and the last address 255 which have special meanings for network management func-
tions. All other 254 combinations are usually free for assigning them to network de-
vices.
For a peer-to-peer connection of a GigE camera to a PC a network address assignment
based on LLA (Local Link Address) is recommended. This involves a network mask
“255.255.0.0” as well as a fixed first part “169.254.xxx.xxx” of the network address
range. A GigE camera will fall back to LLA soon after recognizing that no DHCP server
is available and that no fixed network address was assigned to the camera.
In case a camera can not be reached by the SVCapture application a dialog will appear
that allows for adjusting a camera’s network parameters. The simplest way is to click
