What to do about a sanitation summons on a 3 family?

[Johann Jells]

So I just received a summon in the mail for an infraction 10 days earlier: the recycling was put out too early in the day. It appears to be for $110.  I could pay it, or go to court and see what happens. I'm sure when I tell my tenants about it they will be compliant and not do it again, they're decent high functioning people. 

What I'm trying to figure out is what the authorities would expect me to do about it if I had a non-compliant or vindictive tenant, or even a vindictive neighbor?  I once got a summons for the neighbor placing his trash in front of where I live and it making a mess. This is NJ, where even if I knew for sure which tenant was doing it, there's no way I could get them evicted for premature trash. But I have no idea who it is, I don't live there!  Would I be simply liable indefinitely for whatever they did?  What does the city expect me to do, be there all day, or have a webcam on the sidewalk to run over there in case someone puts their recycling out too early?  Seems to me a law needs to have a practical way to comply, no?
