Why is the IEEE 1394 Standard for digital cameras difficult to synchronize/trigger with other devices?

[Zschocke]

In the knowlege base, it generally says under "analog and digital cameras: advantages and disadvantags" that the IEEE 1394 is difficult to synchronize and trigger. Why is that exactly so and how can you solve that problem in DIAdem 8.0 when you would like to trigger your measurement inputs (accelerometers etc) together with a camera.

I would guess it is difficult to synchronize because it provides a software trigger. Latencies in the communication would make it difficult to perfectly synchronize two separate events.

Many firewire cameras also have a hardware trigger. If you were to use this with your other hardware, you would probably be able to get much better synchronization.
