Active Silicon LFG4

This card offers four independent inputs. You can connect up to sixteen cameras to this card by adding adapters sold by the manufacturer, although this will significantly reduce the frame rate of each input. Alternatively, you can install more than one of these cards at once.

PCI and PCI Express versions of this card are available. We would only recommend using the PCI version of this card in a Mac with PCI-X slots, as older PCI slots do not have enough bandwidth to reliably support all four inputs of this card.

Miglia AlchemyTV DVR

This card offers good quality video and sound input at a very reasonable price. You can install more than one of these cards at once.

There is no PCI Express version of this card, so it is not compatible with the dual-core PowerMac G5 or the Mac Pro.
