For short-term rental hosts
Occupancy alerts.
No cameras. Ever.
Protect your property, reassure your neighbors, and catch a party before the noise starts. 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
How 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 party-level activity — a sudden crowd, sustained 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. crowded party
- Flag unusual or party-level activity, day or night
- Work in the dark, through the space, with no line of sight
It does not
- Count exactly how many guests are present (that needs 2–3 units)
- 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
Precise counting and room-level location come from expanding your coverage. Adding a second or third unit turns one link into intersecting coverage zones, and those zones are what make counting and location possible. It's a law of geometry, not a missing feature — the same reason zone-based monitors sell a sensor per zone. 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
- Party-level activity alerts
- Presence & motion intensity
- One rental, one coverage zone
3-Pack
Indicative — pilot pricing
- Everything in Starter
- Person counting via intersecting coverage zones
- Room-level location across a unit
Why trust a product that isn't shipping yet?
- The sensing runs on a real, open-source stack (WiFi CSI on ESP32 hardware) — the physics is proven and public, not a promise.
- Built by a technical founder productizing that open stack 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 party 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. Party-level 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, party-level one. It is tuned to flag sustained crowd-level activity, not every footstep. It does not produce an exact headcount — that requires 2–3 units working together. We'd rather under-promise than have you disappointed.
Can it tell me exactly how many guests are there?
Not from one device — honestly. Like other zone-based monitors, one sensor tells you the space went from calm to crowded, not whether there are 2 people versus 3. Counting people and locating them by room needs 2–3 units so their coverage zones intersect. That's a law of geometry, not a software update. One unit gives you activity alerts; a 3-pack gives you counting and room-level location.
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.
