FAQ
Frequently asked questions
Earthquake products are easy to oversell. We try to keep the device's limits visible. If your question isn't answered here, write to info@sismosmart.com.
Will this device warn me before an earthquake?
We're talking seconds, not minutes. If the earthquake comes from a distance, the device can catch the fast-moving P wave and send a notification before the destructive S wave arrives. If the epicenter is close, that window shrinks to almost nothing. We don't market this as an early warning system, because it won't work for every earthquake.
Can a single device tell me my building is safe?
It can't. The person who gets to call a building safe or unsafe is an engineer, not a device. What the device does is leave that engineer something solid to work from.
What data do you collect?
Vibration readings, temperature, humidity, pressure and the device's own operating status. We don't link personal information to your device and we don't sell your data to anyone. The Privacy page has the details.
Is my exact location exposed?
We know your device's location at neighborhood level, because we need it to match an event against nearby devices. Anything more precise is only shared under an explicit pilot agreement.
Can researchers access my data?
Only once the data is anonymized and only under a separate agreement with you. That flow doesn't exist yet; it's on the roadmap.
How is this different from Google's earthquake alerts?
Google uses the accelerometer in people's phones. It's free, it's already on every handset, and it works well. But what it measures is the source of the earthquake, not your building. We do the opposite: how your building vibrates, how that changes with the season, what state it's in after an earthquake. A phone can't answer those questions.
What happens when the internet goes down?
The device keeps measuring and saves the event to its own memory. It can't send a notification, because that needs a connection. When the internet comes back, it uploads whatever is waiting.
What happens during a power cut?
There's a small supercapacitor inside. It gives about 30 to 60 seconds of bridge power, which is enough to send the last event to the cloud. A longer outage shuts the device down.
How hard is installation?
You plug the USB-C cable into a socket, stick the device to the wall with the adhesive on the back, and pair it from the app. No drill and no technician. It takes five minutes.
How many devices should one building have?
One will do the job. But with two or three on different floors you can see how the floors move relative to each other, and that's far more valuable for structural health tracking. In apartment pilots we aim for at least three per building.
What do PGA, PGV and MMI mean?
PGA is the peak acceleration the ground reaches during an earthquake, in m/s². PGV is the peak velocity, in cm/s. MMI is the Modified Mercalli intensity scale, which describes how the shaking felt on a range from I to XII. The device reports all three after an event.
What does natural frequency tell you?
Every building has a frequency it tends to sway at. For a five-storey reinforced concrete building that's typically around 2 to 4 Hz. Structural damage drags that frequency down. Because we track it regularly, we can catch a signal while the damage is still early.
Which way should the device face?
There's an upward arrow on the back; point it at the ceiling. Try to align the device's X and Y axes with the building's horizontal directions. Mounted 90 degrees off, the data is still usable, though it carries a little less information.
Does the device record sound?
No. There's no microphone inside, only an accelerometer that measures ground vibration. Recording speech or ambient sound would take an entirely different sensor.
Does my data leave Turkey?
No. We use cloud infrastructure that complies with Turkish regulation. Data is processed in AWS's Turkey and Europe regions and isn't transferred elsewhere.
When does it go on sale?
Pilots start in summer 2026. We're aiming for broad availability by the end of 2026 or early 2027. Certification and manufacturing could push that back. Sign up for the newsletter and you'll hear the firm date first.
