Pentium D 3.0 GHz processor and an Intel PRO 1000 MT network card is an
example of a well equipped system.
NOTE
: All SVS GigE cameras can also be operated with computers of less
performance than the camera delivers at highest frame rate. In this case the
maximal available framerate will be below the camera’s maximum. This is a
valid operating mode, however one has to be aware of the limits.
HINT
:
Notebooks are in most cases not capable to operate data
streams at the maximum level that SVS GigE cameras deliver
. One has to
be aware that connecting a SVS GigE camera to an average notebook will not
allow for operating the camera at highest framerate but only on lower
framerates.

Connecting multiple cameras to a PC
Multiple GigE cameras can be connected to a PC either using a switch or using
dual or quad port network interface connectors (NIC). The following image
shows the basic connection schemes which may also be combined.
HINT: Highest performance requires connecting each camera to a
separate port of a NIC. If on the other hand multiple cameras are
connected to a single NIC using a switch, it might be necessary to
operate those cameras with an “inter packet delay” in order to make
the image data streams run smoothly on a single GigE line.
3.2.6
Multicast
When images from a single camera are to be delivered to multiple PCs the usual
way is to use multicast (RFC 2236). A switch receives an image data stream
from a camera and distributes it to multiple destinations in this mode.
