If an Airbnb host were to list their biggest fears, “guests throwing a party and creating thousands of dollars of damage” would probably be featured at the top. NoiseAware’s line of internet-connected noise sensors is an attempt to assuage these fears. The company just released an updated third-generation lineup that offers an outdoor sensor for the first time, via The Next Web.

Leaving internet-connected microphones in your house probably isn’t a great idea if you have even the most basic level of respect for the privacy of your guests, which is why NoiseAware’s sensors are only capable of tracking overall noise levels. When the decibel level reaches a certain level for a sustained period of time, the host will get an app notification to tell them that things are awry. The big addition for the updated lineup is a battery-powered outdoor model to presumably help you keep an ear out for any aspiring pool parties. The indoor version that plugs into a standard wall socket also makes a return from previous generations, and it’s now able to detect when a guest might be trying to tamper with it.

Earlier this year, the UK-based Hive released the Hub 360, a smart speaker-sized device that’s able to listen for specific sounds, including glass smashing and smoke alarms. The most common listening device people have set up in their homes is the Amazon Echo. Alexa Guard, Amazon’s attempt at offering sound security for your home, is expected to launch before the end of the year. Similar to the Hub 360, Amazon’s software is designed to listen for specific warning sounds like alarms or smashing glass.

The NoiseAware Gen 3 available to preorder directly from the company now, and it will start shipping next month. The indoor sensor is available for $199 (after an introductory price of $149), while the outdoor sensor is available bundled with the indoor version for $298 (although it’ll initially be available for $223). You’ll also need to factor in a subscription to the monitoring service, which will cost you $99 a year after an introductory price of $79.
