str market mapShort-term rental hosts need to prevent unauthorised parties and protect properties and neighbours from noise complaints, but many jurisdictions restrict or prohibit audio and video recording inside rentals.
RentEye is a Polish hardware-and-software company making a subscription-free noise monitoring device for short-term rental properties. The product is a physical sensor that plugs into a wall socket, connects via Wi-Fi, and measures ambient sound in decibels without recording audio content. It ships with a companion iOS and Android app.
The sensor monitors sound intensity in real time and sends instant push notifications when noise levels exceed configurable thresholds. Hosts set quiet-hour windows and decibel limits, and the system flags party-level events for immediate intervention. Automated daily PDF reports summarise 24-hour sound history as incident evidence. Tamper detection alerts hosts if someone tries to disconnect or cover the sensor. Differentiators include a one-time purchase model with no recurring subscription after the initial hardware cost of 129 euros (139 USD), and strict privacy compliance: only decibel readings are captured, never audio. The device is registered in Bialystok, Poland.
