The party gets stopped before it becomes a renovation
Most short-term rental damage is not theft but the things nobody notices in time: a late-night party, more people than agreed, smoking indoors, air that goes bad. Anonymous sensors detect the early signs of these — a noise spike during quiet hours, a rise in the number of people, smoke, CO₂ and PM2.5 — and warn the guest first with an automatic message, then you, only if it continues. You are not watching anyone; you are catching a problem while it still costs euros, not a month of repairs.
What the property notices before you have to worry
Noise and parties — a warning from the earliest signs
The noise sensor watches the level, not the conversation, and notices a spike during quiet hours or a long loud stretch that points to a party. The system first sends the guest a polite automatic quiet-hours message and only alerts you if the noise continues. Most situations resolve on the first message — before the neighbours call or the party gets out of hand.
How many people, with no camera in the room
An anonymous occupancy sensor estimates how many people are in the room without photographing or identifying anyone. If you rented to one or two but there are ten inside, you — and optionally the guest — get an alert. It is the most common signal of a house party or overcrowding, and it comes as a number, not a privacy-invading image.
Smoking and air quality
The air sensor notices smoke, tobacco or other fumes and tracks CO₂, PM2.5 and TVOC levels. Smoking indoors — one of the most expensive and annoying violations — shows up immediately, not from the cleaner’s nose the next day. The same sensor also warns of stale air or humidity that, over time, feeds mould.
Outside: plate-based access and empty-property watch
Outdoors, AI cameras handle number-plate-based gate or car-park access and detect a person or animal when the property should be empty between visits. So you know, without driving over, that the property is clean, empty and intact between stays — and that nobody has been left inside where nobody should be right now.
Every event timestamped as evidence
Every reading and every door event is saved with a timestamp, so there is clear evidence if a deposit dispute ever comes up. You do not have to prove one word against another that there was a party or that someone smoked — the data shows when the level rose and when it fell. The goal is fewer night-time calls and fewer surprise repairs, not watching anyone.
Friday midnight, a noise spike — and a party that never got going
The old way, the owner learned of a party when the neighbour called on Saturday morning, and on the property they found a broken table, the smell of smoke and a deposit dispute. With sensors it went differently. At 00:40 on Friday the noise level rose above the quiet-hours limit and stayed there — the system was not listening to conversation, only to the level. The guest immediately got a polite automatic quiet-hours message. At the same time the occupancy sensor showed that a two-room flat rented to two people held considerably more, and the air sensor noticed a rise in smoke. A second, firmer message went to the guest; the owner got a text saying what was happening. Half an hour later the noise and the number of people fell back — the party was stopped before it became damage. In the morning the log showed the whole story with timestamps, and no deposit dispute arose, because it was all there in black and white.

Security — answers
Do you record guests or listen in?
No. The system is built to detect the problem, not the person. The noise sensor measures the level and pattern, not the words — it knows it is loud but does not listen to or record a conversation. The occupancy sensor estimates the number of people anonymously, without photographing or facially identifying anyone. Cameras are outdoors, for access and empty-property watch, not in living spaces. All indoor data is metrics — decibels, CO₂, PM2.5, temperature — not images or audio recordings. This is a deliberate choice: the goal is to give you enough information to prevent damage, and the guest the privacy they expect. Guests should also be told that the property has security sensors, without advertising their exact location.
Do I have to react to every alert myself?
No, and that is the whole point. The system resolves most situations itself before they reach you: a noise spike sends the guest an automatic quiet-hours message, and only if the noise continues do you get a nudge. That way you are not woken by every loud laugh, only by a pattern that genuinely points to a problem. You can set at what level, and for what, you are notified and what the system simply handles itself. Most owners set the automation to resolve recurring small things and keep for themselves only the cases that need a real person — a leak, a repeat party, something unexpected. Your attention stays free for those, not for every reading.
What can I actually do when a sensor detects a party?
The most effective step is an automatic message to the guest, and it works surprisingly well, because people behave differently when they know a violation has been noticed — most parties stop on the first polite quiet-hours message. If that does not help, you get an alert with a timestamp and can decide: call, send a firmer warning, or in exceptional cases end access. The data also gives you grounds to withhold a deposit, because you have evidence, not a guess. The point of the system is not to punish but to stop a small problem before it becomes an expensive one — and to give you a clear picture if something did break after all.
Do the sensors give false alarms?
Any sensor can be wrong, so the system does not react to a single moment but to a pattern. One loud bang is not a party; a sustained high level during quiet hours is. The same logic applies to the number of people and to air quality — what counts is the trend over time, not a single spike. The thresholds are adjustable, so a city flat and a rural cabin do not share the same norm, and the system learns what a given property’s normal baseline is. At first it is worth setting the thresholds cautiously and then tuning them over a week or two, once you see what is normal for that specific property. The goal is that an alert always means something — better rare and accurate than frequent and empty.
