For short-term rental hosts
Occupancy alerts.
No cameras. Ever.
Protect your property, reassure your neighbors, and catch unusual activity before it becomes a problem. A small device plugs into any outlet and senses activity through your rental's ordinary WiFi. No camera. No microphone. No recording. Ever. A noise sensor still puts a mic in the room — this doesn't.
No cameras · No microphones · No recording · Privacy-first by design
Sustained high-activity period at Maple St — continuous elevated motion for the last 25 minutes.
Example alertHow it works
Three steps. Nothing pointed at your guests.
WiFi signals bounce off everything in a room. When people move, those reflections change. Eye of WiFi reads that change the way a thermometer reads heat — a signal, not a picture and not a sound. It measures activity in the room; it never watches or listens to it.
Plug it in
Put the device in an outlet and connect it to your rental's WiFi. That's the whole setup — no wiring, no cameras to mount.
It senses WiFi reflections
Your router already fills the space with WiFi. The device reads how those signals reflect off movement — presence, motion intensity, and unusual activity.
You get an activity alert
When it detects a sustained spike in activity — an unusual amount of activity or late-night motion — you get a heads-up on your phone. You decide what to do next.
Honest by design
What one device can — and can't — do
We'd rather tell you the physics than oversell. A single unit senses one WiFi link, so it reports activity, not a headcount.
A single unit does
- Detect presence and whether a space is occupied
- Read motion intensity — calm evening vs. a lot of activity
- Flag unusual or sustained high-activity periods, day or night
- Work in the dark, through the space, with no line of sight
It does not
- Count guests exactly — at any pack size, counting tops out at 0, 1, or 2+
- Pinpoint which room someone is in from one device
- See, hear, or record anything — there is no camera or mic
- Identify people or track individuals
Counting is 0, 1, or 2+ people — that ceiling doesn't change with more units, so don't buy a pack expecting an exact headcount. What expanding your coverage does buy: more rooms covered, multi-node confidence voting so a stray reflection doesn't trigger a false alert, and coarse zone awareness — a general sense of which part of the property has activity. That's why we sell in packs.
Planned pricing
Buy the hardware once. Skip the monthly-per-property bill.
Indicative pricing for the pilot. Most competitors charge a subscription for every property, every month — we're building hardware-forward, so your ongoing cost stays low. Waitlist members get first access and pilot pricing.
Starter
Indicative — pilot pricing
- Sustained-activity alerts
- Presence & motion intensity
- One rental, one coverage zone
3-Pack
Indicative — pilot pricing
- Everything in Starter
- Whole-property coverage across multiple rooms or floors
- Multi-node confidence voting — fewer false alerts
- Coarse zone awareness — which part of the property has activity
At the ~$20/mo per property that noise monitors typically charge, a Starter unit pays for itself in about six months — and there's no bill in month seven.
Why trust a product that isn't shipping yet?
- The sensing is built on proven WiFi-sensing physics (WiFi CSI on standard hardware) — established, peer-reviewed science, not a promise.
- Built by a technical founder turning that science into an honest, camera-free device.
- We're validating demand before manufacturing. Pilot units are expected late 2026. No fake photos, no fake reviews, no "in stock."

Questions
Straight answers
Does it have a camera or microphone?
No — and it never will. There is no lens, no microphone, and no way to add one. The device only reads how WiFi signals reflect off movement, the way a thermometer reads heat. It can't see or hear anything, so there is nothing to record.
Is this a surveillance product?
No — and it's worth being blunt about what it can't do. It doesn't watch, listen, record, identify anyone, follow a person around, or store any picture or sound of your guests. It reads a single signal — how busy the space is — and alerts you when activity spikes to a sustained, elevated level. That's the entire capability. It's an activity sensor, not a way to spy on people.
Is it legal to use in a rental? Do I have to disclose it?
Because there's no camera or microphone, Eye of WiFi avoids the biggest legal problem with rental monitoring — recording guests. Most platforms and jurisdictions still expect you to disclose any monitoring device, and disclosing it is also the smart move: it sets expectations and deters parties before they start. Disclosure rules vary, so check your local rules and platform policy. This isn't legal advice.
What exactly should I put in my listing?
Here's paste-ready copy you can adapt: "This home uses a WiFi-based activity sensor to help prevent unauthorized parties and protect the property and neighbors. It detects how busy the space is — it has no camera and no microphone, and it does not record any image, video, or audio." Disclosing the sensor up front is a host benefit: guests who intend to throw a party are the ones it discourages, and everyone else knows exactly what it does and doesn't do.
Does it help me stay compliant with house rules and local ordinances?
That's the point. Many STR permits, HOA agreements, and city rules cap occupancy or ban events, and a single noise complaint can put your license at risk. Activity alerts let you enforce your own house rules and step in before a gathering crosses your occupancy limit or your city's — so monitoring works in service of staying compliant, not snooping on guests.
How accurate is it? Will it false-alarm?
A single unit reliably distinguishes a quiet space from a busy one. It is tuned to flag sustained, elevated activity, not every footstep. It does not produce an exact headcount — even with multiple units, counting is 0, 1, or 2+, never an exact number. We'd rather under-promise than have you disappointed.
Can it tell me exactly how many guests are there?
No — honestly, at any pack size. What it can tell you is 0, 1, or 2+ people, which is enough to flag "more people than booked" without pretending to an exact headcount. Location is zone-level, not room-level — a general sense of where in the property activity is happening, not a precise room. More units buy wider coverage and fewer false alerts through multi-node confidence voting, not a higher counting ceiling.
Do I need special hardware or a particular router?
No. It joins your existing WiFi like any other device. Your router already provides the signal it senses. You just plug the unit into an outlet.
When can I actually buy one?
The product is in development. We're validating demand now and expect pilot units late 2026. The waitlist is how you get first access and pilot pricing — it is not a store, and nothing ships today.
