Noise Monitor
A decibel sensor that alerts you to a party without recording audio.
Why you care
It is the cheapest insurance against the one event that ends an STR: the neighbour complaint that becomes a code enforcement file.
Worked example
Minut or NoiseAware at $100–$200 plus a small subscription. They measure level only — no recording — which is what keeps them legal indoors.
