How to Check a Hotel Room for Hidden Cameras
To check a hotel room for hidden cameras, do a quick, structured sweep the moment you arrive: darken the room and look for lens reflections around the two highest-risk areas first — the bed and the bathroom — then physically inspect the handful of objects with a direct line of sight to them, such as smoke detectors, alarm clocks, TVs and air vents. The whole pass takes a few minutes, and the point is not suspicion but routine: you confirm the room is private, then you unpack and forget about it.
Hotel rooms are a particular case, different from sweeping your own home. You have limited time, you are unfamiliar with the space, and — the part that actually matters — you have no idea who had access before you or what was installed. That is exactly why a fast, repeatable method beats a one-off deep search. If you are checking a short-term rental rather than a hotel, the same method applies with a few differences. Below is the routine, the specific places cameras turn up in hotels, and what to do if you find one.
What to check first in a hotel room
Cameras are placed to capture something specific, and in a hotel that means two areas above all others: the bed and the bathroom or shower. Start there before anything else. Every hidden camera worth worrying about has a clear, head-on line of sight to one of those two places, so rather than searching the whole room at random, identify those sightlines and scrutinise the objects sitting along them.
For the bed, stand where your head would rest and look outward: what objects face you directly? An alarm clock on the nightstand, a smoke detector on the ceiling above or ahead, the television, a decorative item on the dresser, the air-conditioning unit, a USB charging hub. For the bathroom, the concern is anything with a view of the shower, toilet or sink — vents, toiletry baskets, hooks, tissue boxes, or fittings that seem oddly placed. If you check nothing else, check the items facing those two zones.
A three-minute hotel room sweep
The routine is the same in any room and gets faster every time you do it.
Darken the room. Draw the curtains and turn off the lights. Low light makes camera lenses easier to catch, because a lens reflects light back as a small bright glint.
Scan the high-value objects for a lens. Move slowly past the bed-facing and bathroom items, looking for a pinhole, a tiny reflection, or a glassy point where there should not be one. A dedicated lens finder makes this far more reliable — you look through it while sweeping and a lens lights up — but even a careful naked-eye pass in the dark catches the obvious ones.
Use your phone for two quick checks. In the dark, point your phone's front camera at the suspect objects: some night-vision cameras emit infrared light your eye cannot see but the camera screen sometimes can, appearing as a small white or purple glow. Then open your phone's Wi-Fi and look at the network for device names that suggest a camera — not foolproof, but occasionally it surfaces one hiding in plain sight.
Physically inspect the usual suspects. Pick up or look closely at the objects facing the bed and bathroom. Is anything warm, wired where it needn't be, angled deliberately, or positioned with no functional reason? A smoke detector directly over the bed, a clock aimed at it, a phone charger plugged in across from the shower — these are the patterns to notice.
Check the bathroom last and carefully. It is the highest-privacy area and a frequent target. Look at vents, any baskets or holders, and the underside or back of fittings facing the shower and toilet.
If you would rather be walked through this step by step the first few times, the Room Sweep Companion has a hotel sweep that guides you through each zone in order — it is free and built for exactly this.

Where hidden cameras are most often found in hotel rooms
Certain objects come up again and again, because they sit at the right height, face the right way, and can hide a small lens behind an aperture. In rough order of how often they are the culprit:
Smoke and motion detectors, especially any mounted to face the bed rather than centred on the ceiling. Alarm clocks and clock radios on the nightstand. Televisions and the boxes or soundbars beneath them. USB charging hubs and plug-in adapters, which now come pre-fitted with cameras and sit conveniently near the bed. Air-conditioning units and vents. Decorative objects — picture frames, fake plants, ornaments — positioned with a clean view of the bed. And in the bathroom: vents, toiletry baskets, hooks, and shelf items angled toward the shower.
The unifying tell is sightline plus oddity: an object that both faces a private area and seems slightly out of place — too angled, too new, too conveniently positioned — earns a closer look. We go deeper on the full list of concealment spots in the complete detection guide.
Can you check a hotel room with just your phone?
Up to a point, and it is worth being honest about the limit so you are not falsely reassured. A phone does two useful things: its front camera can sometimes reveal a night-vision camera's infrared LEDs in a dark room, and a Wi-Fi scan can occasionally list a camera on the network. That is a reasonable first pass, and better than nothing when you are travelling light.
But a phone cannot see a camera that records to a local memory card, one that is powered off, or one on its own separate network — and those are common. So a phone is a screen, not a sweep. A compact lens finder and a small RF detector — both of which fit in a wash bag — do what a phone structurally cannot, which is why frequent travellers carry them. We cover the phone-only method in detail in a dedicated phone-method walkthrough, and the travel-sized equipment that closes its gaps on the counter-surveillance equipment page.
What to do if you find a camera in your hotel room
Stop and act deliberately rather than on impulse. Do not pull the device out or unplug it — its position and storage may matter, and a disturbed device is weaker as evidence. Photograph it exactly where it is and note what it could see. If you believe it may have a live microphone, do not discuss what you have found out loud in the room.
Then escalate appropriately. Contact the front desk or hotel management and request a different room or to check out — and ask for the find to be documented. Depending on the seriousness and your location, this may also be a matter for the police; covertly recording guests in private accommodation is a criminal offence in Switzerland and across the EU, not a service complaint. If you booked through a platform, report it to them as well, with your photographs. Prioritise your own safety over investigating the device yourself, and if anything feels threatening, leave first and report from somewhere else.
Is it legal for a hotel to film inside a room?
No — and the distinction is clear and on your side. Hotels and hosts may use cameras in genuinely public areas such as lobbies and corridors, but recording inside a private guest room, and anywhere with an expectation of privacy like a bathroom, is unlawful across Switzerland and the EU. Just as importantly, checking your own room is entirely lawful: you are free to inspect a space you are occupying for devices. The thing the law restricts is the covert recording of people without consent — which is precisely what you are protecting yourself against, not doing.
Do this in three minutes on your next trip
The reassuring part of this is that it becomes second nature. Once the routine is familiar, checking a room costs a few minutes at check-in and buys you the rest of the stay without a second thought. If you want it guided, run the free hotel sweep in the Room Sweep Companion. If you would like the procedure as a printable reference to carry, the travel field guide lays it out step by step. And if you travel often enough to want the equipment that turns a good check into a thorough one, the compact lens finder and RF detector in the travel kit on our counter-surveillance page are made to fit a carry-on.
A private room should be private. Now you can confirm it is — and get on with your trip.
Frequently asked questions
How do I check a hotel room for hidden cameras quickly? Darken the room, then look for lens reflections around the bed and bathroom first — those are the two areas cameras target. Inspect the objects facing them, such as smoke detectors, alarm clocks, TVs and USB chargers, and use your phone's front camera in the dark to spot any infrared night-vision lights. The pass takes a few minutes.
Where are hidden cameras usually placed in hotels? Most often in objects with a direct line of sight to the bed or shower: smoke and motion detectors, alarm clocks, televisions, USB charging hubs, air vents, and decorative items. In bathrooms, check vents, baskets and fittings facing the shower.
Can a phone detect a hidden camera in a hotel room? Partly. A phone's front camera can sometimes reveal a night-vision camera's infrared lights in a dark room, and a Wi-Fi scan may list a networked camera. But a phone misses cameras that record locally or are powered off, so it is a first pass rather than a reliable sweep.
Is it illegal for a hotel to have a camera in the room? Yes. Recording guests inside a private hotel room, and anywhere with an expectation of privacy such as a bathroom, is unlawful in Switzerland and across the EU. Cameras are only permitted in genuinely public areas like lobbies. Checking your own room for devices is entirely legal.
