Why a sensor rather than a report
An owner who isn't on site knows the business only through what people choose to tell them. The hotel register shows twelve rooms let; the till takes payment for nine. The warehouse guard insists the door was opened only for the morning delivery. The monthly report arrives clean, coherent, and thoroughly unverifiable.
The problem isn't dishonesty: most teams are honest. The problem is that a human report has nothing to be compared against. There is no second source to check it with, so there is no way to tell a mistake from a fraud, or either of them from a genuinely quiet night.
PTB Presence supplies that second source. A measured, timestamped reading that depends on nobody's account: the room was occupied or it was not. What you do next (cross-checking footfall against takings, explaining an energy bill, settling a dispute) stays your decision. The sensor doesn't judge, it records.
What the sensor measures, and what it cannot see
Presence detection works without a camera. The unit senses that a person is in the room; it produces no image, records no sound, and cannot identify anyone. That limitation is deliberate: it makes the device installable in a hotel room or an office without raising the question of consent to video surveillance.
Each unit also reports the room's temperature, humidity and air quality: volatile organic compounds, equivalent carbon dioxide, air quality index. Each of those has its own use: a room at 34 °C explains a complaint, sustained high humidity foretells damage to furniture, air degrading in a classroom is fixed by opening a window.
On top of that come a fire alert and a tamper alert. The first is sent without waiting for the next scheduled reading; the second reports that someone tried to open the device, which is information in itself.
The installation needs no cables and no sockets
A sensor runs for several months on its battery. When it reaches a critical level, PTB technicians come and replace it.
An internet outage doesn't interrupt the system's operation.
What you see, and when
The dashboard opens in a browser, on a phone or a computer, and installs to the home screen like an app. It shows the current state of every room, occupancy history over several months, and the conditions measured in each space.
Alerts (fire, tampering, thresholds crossed) reach the phone as they happen. The monthly report sums up the period and serves as evidence when a discussion starts.
What setting it up involves
Reckon on one sensor per room to be monitored, and one modem per site. The modem is configured from a phone over Bluetooth: you give it the local Wi-Fi and the customer identifier. There is no cabling to run, no drilling, and no work on the electrical installation.
PTB technicians install the hardware and check on site, room by room, that every sensor communicates properly with the modem. Alert thresholds and user accounts are then set from the dashboard, and our team stays on hand to help you adjust them.
Frequently asked questions
Is there a camera or a microphone in the sensor?
Neither. The PTB device detects that a person is present, but produces no image and records no sound. It cannot identify anyone.
How long does a sensor's battery last?
Several months. When the battery reaches a critical level, PTB technicians come and replace it.
What happens if the site loses internet?
Measurement continues. The modem keeps the last hundred readings in memory and sends them as soon as the link returns, leaving no gap in the history. On your side, the dashboard opened offline shows the last known situation and states its date.
Do you need to run cables or drill into walls?
No. The sensors run on battery and communicate wirelessly. Only the site modem needs a power socket and Wi-Fi access.
Does it work in a building without Wi-Fi in every room?
Yes. The sensors don't need internet: only the site's PTB modem has to be connected to Wi-Fi.
Who can see my site's data?
You, and the accounts you create yourself. Each customer is isolated from the others, and a site owner manages their own users and what each of them is allowed to see.
