Quick Answer: Do a dark-room flashlight sweep for lens glint, check your phone’s Wi-Fi settings for unfamiliar device names on the network, and use your phone’s camera in a darkened room to spot the faint infrared glow of an active night-vision LED — together these three free checks catch most wireless hidden cameras in a rental. A dedicated RF detector adds a fourth layer for wireless transmitters specifically, but nothing catches a camera that only records locally with no wireless signal at all, so combining methods matters more than any single trick. According to a 2025 IPX1031 survey, 47% of renters say they’ve found a hidden camera in a rental property — nearly double the 25% who said the same in 2023 — which is why a five-minute check is worth doing on arrival.
Published September 21, 2026.
Nearly half of renters surveyed in 2025 say they’ve found a hidden camera somewhere in a vacation rental, up sharply from just a quarter of renters two years earlier, according to IPX1031’s annual surveillance study — and separately, 58% of Americans say they’re now actively worried about it before booking. Whether that jump reflects more cameras or just more people knowing to look for them, the practical takeaway is the same: a quick check on arrival costs nothing and takes about five minutes.
The four checks, in order of speed
| Method | What it catches | What it misses | Time |
|---|---|---|---|
| Flashlight glint sweep | Any lens, wired or wireless | Lenses hidden behind opaque covers or angled away from your sweep | ~2 min |
| Wi-Fi network check | Wi-Fi-connected cameras on the same network | Cellular cameras, local-only cameras, cameras on a separate hidden network | ~1 min |
| Phone-camera IR check | Active night-vision IR LEDs, in the dark | Cameras that are off, have no IR, or are behind a cover | ~2 min |
| RF detector sweep | Any actively transmitting wireless signal (Wi-Fi/Bluetooth/cellular) | Locally-recording cameras with no wireless transmission | ~5-10 min |
1. The flashlight glint sweep. Turn off every light and use your phone’s flashlight (or a small handheld one) held close to your eye, sweeping it slowly across shelves, vents, smoke detectors, picture frames, and clocks at a low angle. A camera lens reflects light differently than the surface around it — you’re looking for a small, sharp glint rather than the object itself. Smoke detectors, alarm clocks, power outlets, USB wall chargers, and picture frames are the hiding spots that come up most often across hidden-camera-detection guides, so give those specific objects extra attention in the bedroom and bathroom first.
2. The Wi-Fi network check. Open your phone’s Wi-Fi settings and look at the list of devices connected to the property’s router if the app or router admin page exposes it — most mesh-router apps and some phones will show connected device names. An unfamiliar device named something like “IPCAM” or a string of random characters is worth investigating further. This only catches cameras sharing the same network you’re on; a camera transmitting over its own cellular connection or a separate hidden network won’t show up here.
RF (radio frequency) hidden camera detector
- Catches wireless hidden cameras a flashlight sweep alone would miss, especially ones tucked behind covers.
- Blind to cameras recording locally to a microSD card with no wireless transmission — pair it with the flashlight sweep, not instead of it.
- Compact enough to pack in a carry-on for hotel and Airbnb trips.
Traveling for work and staying in a lot of short-term rentals this year? A free Amazon Business account makes it easy to keep a detector and a few other travel-security basics on a recurring restock without juggling a personal cart.
3. The phone-camera infrared check. Many hidden cameras use infrared (IR) LEDs for night vision, invisible to the naked eye but often visible to a phone’s camera sensor. In a fully dark room, hold your phone up and slowly scan around — an active IR LED typically shows up on screen as a small purple or white dot that isn’t visible in person. This only works if the camera’s IR night vision is currently active, so it’s a useful extra pass rather than something to rely on alone.
4. The full RF detector sweep. For the most thorough check — especially useful in a space you’ll be staying in for more than a night or two — walk the room slowly with a dedicated RF detector, paying closer attention near outlets, smoke detectors, and any object that seems slightly out of place for the room. Turn off your own phone’s Wi-Fi and Bluetooth first so the detector isn’t picking up your own device’s signal.
Why this matters more in 2026 than it used to
What changed: Airbnb's indoor camera ban
- Airbnb now bans all indoor security cameras and recording devices globally — visible or hidden, on or off — even if a host discloses them in the listing.
- Outdoor cameras are still allowed but must be disclosed and can't point indoors or into private outdoor spaces like a shower or sauna.
- Despite the ban, the same 2025 IPX1031 survey found 55% of hosts admit to still using an indoor camera somewhere in their property.
That gap between the policy and reality is exactly why the check-on-arrival habit is worth keeping even though Airbnb technically prohibits indoor cameras outright. A hotel room carries a different legal backstop rather than a platform policy: secretly recording a guest in a space where they have a reasonable expectation of privacy — a bedroom or bathroom — is a criminal offense in nearly every U.S. state, not just a terms-of-service violation, regardless of who owns the property. Our security camera privacy laws guide covers the broader legal line between lawful recording and unlawful surveillance in detail.
If you actually find one
Don’t unplug or damage it right away — a camera you’ve disabled is also a camera you’ve destroyed evidence on. Photograph it in place, note the exact location, and if you’re comfortable doing so, leave the immediate area. For an Airbnb, report it through the app’s Safety Line rather than messaging the host directly; because indoor cameras are an automatic policy violation as of the 2024 ban, Airbnb doesn’t need you to prove intent, only that a camera was there. For a hotel, report it to management and consider involving local police, since it may constitute a criminal act rather than a policy breach.
The other side of this: securing your own home
Everything above is about spaces you don’t control. If you’re setting up cameras in your own home and want to place one more discreetly without crossing into someone else’s privacy, our how to hide a security camera guide covers camouflage and placement — including why hiding your only camera can actually reduce its deterrent effect against burglars. And if you’re weighing a hidden-style camera as an actual purchase rather than trying to spot someone else’s, our best hidden camera guide ranks the top covert and disguised picks for legitimate home and business use.
The bottom line
No single method catches every hidden camera, but a flashlight sweep, a Wi-Fi device check, and a phone-camera IR scan together take under five minutes and catch the large majority of wireless hidden cameras reported in rentals. An RF detector is worth packing if you travel often or are staying somewhere longer-term. And if you do find something, document it before you touch it — for an Airbnb, Airbnb’s 2024 indoor-camera ban means you don’t have to argue about disclosure, just report it.
