It seems like they're saying you ring the bell when you see a fish, and that notifies the lock operator, who probably checks the same camera to verify it, then opens the locks if certain conditions are met. So, the advantage is that the operator can do other things besides watching the camera all the time, knowing that helpful people on the internet will alert him when needed. Does that work in practice, especially after the site goes viral? I'd assume there would be a ton of false positives, i.e. people ringing the bell for the lulz. If it's just a fun community thing, and the alert actually goes to the equivalent of /dev/null, that that's fine. Maybe a better metaphor would be those buttons on cross-walks that aren't attached to anything, but make you feel like you're influencing the light sequence when you press them. Anyway, I just don't get how this would work well in practice.
