Note: Other Series 2 OAK PoE cameras require some creativity and an external signal generator (documentation here) to be hardware synchronized. Y-adapter provides true hardware frame sync capability syncing frames on multiple cameras precisely. 2x female-to-male cables need to be used with the FSync Y-adapter; 1. cable connecting the Y-adapter to the OAK's M8 connector 2. cable connecting to the next Y-adapter in the chain, so it can be daisy-chained
