What is the maximum number of DV cameras I can have connected to my machine?
If you have a desktop machine with available PCI slots, then you can have as many cameras as you have card slots free for. We recommend using a separate FireWire PCI card per camera for compatibility reasons. You may find that multiple cameras will work fine when connected to the same card (bus), but this is not a configuration we support. Generally speaking, it’s older cameras that have problems working together on the same bus. If you want to use multiple devices on a laptop, you can add an additional FireWire PC card (PCMCIA). On Mac hardware, please be aware that the FireWire 800 and 400 buses are actually connected together and so can’t offer the additional camera support that multiple buses afford.
