A loud noise sounds
This, if you have a very isolated house. A friend of mine set up an extremely loud battery powered horn, fixed to the ceiling, so hard to reach, in his mostly uninhabited country house.

Can't use that method in an apt building though !

I don't think there's much possibility to hack the system since to only option you have is to agree or not. And if not I guess you need to file manually.
