To check a hotel room for hidden cameras, run a quick four-part sweep with your phone the moment you walk in: a flashlight lens check in the dark, a WiFi scan, a Bluetooth scan, and a magnetic check. Together they take a couple of minutes and catch almost every hidden camera. Here's how, where to look in a hotel specifically, and what to do if you find one.
Are there really hidden cameras in hotels?
It happens, but it's rarer than in short-term rentals — and the reason is structural. A hotel room is cleaned by professional staff every day, turned over hundreds of times a year, and maintained by people who would notice an out-of-place gadget. A private host's apartment has none of that oversight.
So the realistic risk in a mainstream hotel is low. It rises with smaller, independent properties, and with rooms that have been rented short-term through a third party. Low risk isn't zero risk, and the check costs you two minutes — so it's worth doing, especially for a room you'll undress and sleep in.
Where hidden cameras hide in a hotel room
The disguises overlap with rentals, but a few spots are especially worth your attention in hotels:
1. The TV and cable/streaming box
Front-facing, mains-powered, pointed straight at the bed, and rarely questioned. The standby LED area is a natural place to tuck a lens.
2. Smoke and CO detectors
Ceiling-mounted and pointing down — the ideal surveillance angle. A glossy black dot that looks different from a real sensor is the flag.
3. Alarm clocks and bedside electronics
Bedside devices cover the bedroom, where privacy matters most. Be wary of a new-looking clock in an otherwise dated room, or a cord thicker than a clock needs.
4. The bathroom
The most serious place to check. Look at vents, the underside of shelves, toiletry baskets, and any decorative object with a clear line to the shower or toilet. A bathroom camera is never legitimate.
5. Air vents, AC units and thermostats
Grilles and louvers give natural cover for a lens while staying powered.

How to check a hotel room for hidden cameras: a 4-step sweep
Do this before you unpack. Each step takes about fifteen seconds.
Step 1 — Flashlight lens sweep
Turn off the lights, let your eyes adjust, and sweep your phone flashlight slowly across the room at eye and bed level. A camera lens is glass, and glass throws back a bright pinpoint glint along its line of sight. Move the beam side to side — lenses reflect only at certain angles, so a static light can miss them. This is the single most reliable check, because it works whether or not the camera has any wireless signal.

Step 2 — WiFi network scan
Join the room's WiFi and list every device on the network. Hidden IP cameras need a connection to stream, so they appear in the list. Look for camera brands — Hikvision, Reolink, Ezviz, Wyze, Tuya — and unbranded devices with unfamiliar MAC addresses.
The hotel caveat: big shared hotel networks are crowded, so a device list is noisier and harder to read than in an apartment. Some hotels also isolate each room, which hides other devices entirely. Treat WiFi as one signal of four here, not the deciding one. Bluewex's WiFi scanner labels the manufacturer for each device to cut through the noise.
Step 3 — Bluetooth scan
Scan for nearby Bluetooth Low Energy devices to surface BLE cameras and any stray trackers — the same scan finds an AirTag someone may have slipped into your bag. If that's a worry, see how to find an AirTag tracking you. Bluewex's BLE scanner shows live signal strength so you can locate the source.
Step 4 — Magnetic field check
Powered electronics give off a magnetic field, and your phone's compass sensor can detect it up close. Sweep slowly across the TV, smoke detector, alarm clock, and bathroom fixtures. A spike where there shouldn't be one is a sign of concealed electronics — and it catches local-recording cameras that the WiFi and Bluetooth scans miss entirely.
The two-minute checklist
In order, starting at the door:
- Lights off, curtains closed — flashlight sweep at bed and eye level.
- Bathroom next, same sweep. Vents, the undersides of shelves, anything facing the shower or toilet.
- Join the room WiFi and read the device list. Note anything carrying a camera brand name.
- Bluetooth scan from the middle of the room, then again beside the bed.
- Magnetic sweep over the TV, smoke detector, alarm clock and bathroom fixtures.
- Lights back on. Unpack.

Can you find a hidden camera with just your phone?
Mostly, yes — and it is worth being precise about where the line falls, because a lot of advice online oversells it.
What your phone catches well:
- Any lens with a clear line of sight to you. The flashlight glint test is optical, not electronic. It does not care whether the camera is networked, battery-powered, or recording to a memory card.
- Networked cameras. A WiFi scan lists devices streaming over the room network, usually with a manufacturer name attached.
- BLE cameras and trackers. A Bluetooth scan surfaces anything broadcasting nearby, with signal strength to walk you toward the source.
- Concealed powered electronics. The magnetometer picks up the field from a device hidden inside an ordinary object, even one that is offline.
What it will not catch:
- A wired camera on the building's own network, which never touches the guest WiFi at all.
- A camera that is fully powered down while you scan. The lens test still works on it; the three electronic checks do not.
- Anything with no sight line to you — which is the reassuring half of the trade-off: a camera positioned to film you is also positioned to reflect your flashlight back.
The infrared myth. You will read that you can spot a hidden camera by looking for glowing IR LEDs through your phone camera in a dark room. It is half true. Most rear cameras have an infrared filter that blocks exactly this. Many front-facing cameras do not, so the selfie camera is the one to try — and even then it only reveals cameras using active IR illumination at night. Treat it as a bonus check, never as a replacement for the flashlight sweep.
No phone can run a true radio-frequency sweep the way a dedicated RF detector does. For a traveller that gap rarely matters: the four checks above cover the cameras people actually plant in hotel rooms.
Is it a camera, or a false alarm?
Most things that look alarming on a first sweep turn out to be nothing. Before you call the front desk, rule these out:
- A glint that smears when you move. Polished screw heads, plastic trim and varnished wood all throw light back. A lens glint stays a tight, bright pinpoint and appears only from a narrow angle; a surface reflection spreads and slides as you shift position.
- A real smoke detector. Genuine optical detectors have a visible dark chamber opening. The tell for a fake is a smooth glossy dome, or a pinhole sitting off-centre from the sensor housing — plus a unit that looks noticeably newer than everything else on the ceiling.
- Unknown WiFi devices. On a hotel network, most unfamiliar entries are other guests' phones, smart TVs, printers and access points. A device is only interesting if its manufacturer maps to a camera vendor.
- A magnetic spike near the TV or air conditioner. Those are large powered appliances and will always register. What matters is a spike coming from an object that should contain no electronics at all — a book, a tissue box, a decorative ornament.
The threshold worth acting on is two independent checks pointing at the same object. A lens glint plus a magnetic spike from the same alarm clock is worth a phone call; either one on its own usually is not.
What to do if you find a camera in a hotel
- Document it — photo and video showing the device and its location. Screenshot any app result that flagged it.
- Don't disturb it. Don't unplug or cover it yet; in an investigation it matters in place. Assume it may capture audio.
- Leave the room before you make decisions or discuss anything.
- Report it. Go to the front desk first; if they're dismissive, escalate to a manager and ask for a different room or property. For anything that looks intentionally hidden — especially in a bathroom — file a police report. Hidden surveillance in private spaces is illegal in most US states and EU countries.
What to say at the front desk. Keep it short and factual: the room number, the object, where it sits, and what you want to happen. Something like — "There is a device in room 412 that I believe contains a camera. It is on the shelf facing the bed. I have photographed it and left it in place. I would like to speak to a manager and be moved to a different room." Naming the object and confirming you have already documented it moves the conversation past a shrug. If you are told the device is simply "part of the room", ask for that in writing.
Hotels vs Airbnbs
If you stay in both, the method is the same but the odds differ: lower in professionally run hotels, higher in private short-term rentals. For the rental side — including how common this actually is — see do Airbnbs have hidden cameras? and the full Airbnb safety scan.
Frequently asked questions
How do I check a hotel room for hidden cameras?
Run four checks on arrival, before unpacking: a lights-off flashlight sweep for lens glints, a WiFi network scan, a Bluetooth scan, and a magnetic field check with your phone's compass sensor. Each takes about fifteen seconds, and together they catch almost every hidden camera.
Are hidden cameras common in hotels?
Less common than in short-term rentals. Hotels are cleaned and maintained daily by staff who would notice odd devices, which lowers the risk — but it isn't zero, especially in smaller independent properties. A two-minute check is still worth it.
Do hotel rooms have cameras?
Hotels can legally use cameras in public areas — lobbies, corridors, parking. Inside guest rooms and bathrooms, cameras are illegal in most US states and EU countries, full stop. So a camera in your room is never "hotel policy"; if you find one, report it.
Where should I look first in a hotel room?
The TV and cable box, ceiling smoke detectors, bedside alarm clocks, air vents, and — most importantly — the bathroom. Any object with a clear line of sight to the bed or shower deserves a closer look.
Can I detect a hidden camera on hotel WiFi?
Sometimes. A WiFi scan lists networked cameras, but large shared hotel networks are noisy and some isolate each room, so a camera may not appear. Use the WiFi scan alongside the flashlight and magnetic checks rather than on its own.
What do I do if I find a camera in my hotel room?
Document it, leave it in place, step out of the room, and report it to the front desk and then management. File a police report if it appears intentionally hidden, particularly in a bathroom. Hidden surveillance in private spaces is illegal in most US states and EU countries.
Can you detect hidden cameras with your phone?
Yes, for the great majority of them. Your flashlight reveals lens reflections, a WiFi scan lists networked cameras, a Bluetooth scan surfaces BLE devices, and the compass sensor detects concealed powered electronics. A phone cannot run a true radio-frequency sweep like a dedicated RF detector, but those four checks cover the cameras realistically found in hotel rooms.
Do you need an app to check a hotel room for cameras?
No. The flashlight sweep needs nothing but the torch, and both WiFi and Bluetooth device lists are reachable from your phone settings. An app mainly saves time by naming the manufacturer behind each device and running the four checks in sequence instead of one at a time.
Can a hidden camera record without WiFi?
Yes — plenty record locally to a memory card and never join any network, which is exactly why a WiFi scan alone is not enough. The flashlight lens sweep and the magnetic field check are the two that still find an offline camera.
The bottom line
Hidden cameras in hotels are uncommon, but a four-part sweep with your phone settles the question in a couple of minutes — and the bathroom check alone is worth the time. Do it on arrival and you can relax for the rest of the stay.
If you want help running the sweep, that's exactly what Bluewex does — free on iOS and Android.
