1.10 Installing Two Cards
You can install two video capture cards of the same model for a total of 32 channels. For
example, 2 x GV-650A Cards (16 channels) = 32 channels.
It is also possible to implement two video capture cards of different channels. For example,
GV-650A Card (12 channels) + GV-650A Card (16 channels) = 28 channels.
Note:
Besides GV-804A Card and GV-600B / 650B / 800B Card with PCI interface, all GV
video capture cards support two-card mode.
Rules to Use Two Cards
GV video capture cards have two interface types: PCI and PCI Express (PCI-E). When you
install two video capture cards, ensure they are installed in the right slots as instructed in the
following tables.
