Some cameras include features that add more latency than you would expect. For
instance, image stabilization (by definition) adds one field of latency and sometimes
more. Disable anything of that sort that you can.
Latency may be slightly lower for progressive sessions, so for lowest latency, (genlocked)
720p cameras and session are theoretically ideal.
