What is the difference between Wired Sync and OptiSync?
Wired sync provides camera-to-camera sync using an extra set of cables in a daisy chain arrangement in addition to the USB cables. Wired sync is available for FLEX:V100, SLIM:V100, FLEX:V100R2 and V120:SLIM cameras. See FAQ entry 2-17 for information about which cameras can be used together in the same sync chain. OptiSync is NaturalPoint’s custom synchronization system, which sends and receives sync signals over the USB cable. No extra sync cable is required. OptiSync is only available when using FLEX:V100R2 cameras connected to OptiHubs.
