How to Find Hidden Cameras in Your House
To find hidden cameras in your house, work room by room in low light and check the objects with a clear view of the places you would least want recorded — bedrooms, bathrooms and anywhere you undress or speak privately. Look for the small bright reflection a lens gives back, inspect the objects that plausibly hide one, and use an RF detector to catch any camera that is transmitting. A lens finder makes the optical check far more reliable, because a lens reflects light whether or not the camera is switched on.
Unlike a hotel or a rental, your home is a space you control — which changes both who might have placed a camera and where they would have had the opportunity.
Who places cameras in a home, and when
Motive and access are what turn a worry into a reason to check. In a home, a camera is almost always placed by someone who had legitimate entry at some point: a former partner during or after a relationship, a landlord or letting agent with a key, a contractor, cleaner or houseguest, or someone who visited once with a gift or an object they left behind. Occasionally the opportunity is an actual break-in — one where, tellingly, nothing was taken.
If none of that applies, the odds are low, and it is worth saying so plainly: most people who worry about this find nothing, because there was never an opportunity. If some of it does apply — a bad separation, a period when keys were out of your control, an unexplained object — then a check is a reasonable, proportionate response rather than paranoia.
The rooms and sightlines that matter
Cameras are placed to see something specific, so search by sightline rather than sweeping every square metre evenly.
Bedrooms are the most common target. Stand where you sleep and dress, and look outward: what objects face you directly? Bathrooms are next, and the concern is anything with a view of the shower, bath or toilet. Living areas and home offices matter if the interest is in conversations, visitors or what you work on. Entrances and hallways are usually about comings and goings rather than privacy.
Work each room from the point of view of the person who would want to watch it. Whatever they would need to see, something must face it.
Where hidden cameras are actually concealed
The recurring hiding places are recurring because they sit at the right height, face the right way, and hide a lens behind a small aperture without looking odd.
Smoke and carbon-monoxide detectors, especially any mounted to face a bed rather than centred on a ceiling. Alarm clocks and clock radios on a bedside table. USB chargers, plug adapters and power strips, which solve the battery problem by sitting permanently powered. Air purifiers and air-conditioning units. Televisions and the boxes or soundbars beneath them. Picture frames, ornaments, artificial plants and books on a shelf with a clean view of the room. Vents. And in bathrooms: extractor vents, toiletry baskets, hooks, shelf items and fittings angled toward the shower.
The tell is always the same combination — an object with a private sightline it has no reason to have, or an item that is newer, warmer, more wired or more deliberately angled than it should be. Anything that arrived as a gift, or that you cannot account for, deserves particular attention.
A room-by-room method
Darken the room. Close curtains, turn off the lights. Lenses are easiest to catch in low light.
Do the lens sweep. Move slowly past the objects facing the bed, the shower, or wherever matters, watching for a small bright pinpoint of reflected light. A lens finder — a ring of LEDs around a viewport — makes the glint far easier to see, and works whether or not the camera is powered. With bare eyes and a torch held beside your head, you can do a rougher version of the same thing. Move slowly and look from a few angles; a lens only glints at the right one.
Check for infrared. In the dark, pan the room with your phone''s front camera and look for a small white or purple glow invisible to the naked eye — some night-vision cameras give themselves away this way. We cover the phone methods, and their limits, in finding a hidden camera with your phone.
Run an RF sweep. Turn off your own wireless devices first — phones, laptops, smart speakers, the router if practical — then move an RF detector slowly through the room and watch for the signal strengthening toward a source. This catches cameras that are actively transmitting; it will not catch one recording to a memory card or currently powered off, which is exactly why the optical and physical checks are not optional.
Inspect physically. Pick up and look closely at the objects on your list. Is anything unfamiliar, warm, wired where it needn''t be, or angled deliberately? Check behind and beneath furniture, and inside anything that arrived without clear provenance.

Cameras and listening devices are different problems
A camera has a lens, which is why optical detection works. A listening device does not, and is found differently — by RF sweep if it transmits, or by physical search if it merely records. If your concern is audio rather than video, or both, the method and the hiding places differ enough to be worth their own walkthrough: see how to tell if your house is bugged, and the complete detection guide for how the layers fit together.
If you find one
Do not pull it out. Photograph it exactly where it is, note what it could see, and do not announce the find aloud if a microphone may be live. Recording someone in their own home without consent is unlawful across Switzerland and the EU, so this is very likely a matter for the police rather than something to resolve privately — and an undisturbed device is far better evidence. If the situation involves someone who may become dangerous, prioritise leaving and reporting from somewhere safe over investigating further.
Checking your own home is entirely legal
Worth stating plainly: you are free to inspect a space you live in for devices, and no permission is required. What the law restricts is the covert recording of others — which is the thing being done to you, not by you. The field guides lay out the home sweep as a printable reference, and the lens finders and RF detectors that make it thorough are on our counter-surveillance equipment page.
Your home is the one place you should never have to perform. A methodical check is how you confirm you do not.
Frequently asked questions
How do I check my house for hidden cameras? Work room by room in low light, prioritising bedrooms and bathrooms. Look for the bright pinpoint reflection of a lens on objects facing the bed or shower, pan the dark room with your phone''s front camera for infrared glows, run an RF detector to catch transmitting cameras, and physically inspect anything unfamiliar or oddly angled.
Where are hidden cameras usually placed in a house? In objects with a direct view of private areas: smoke detectors, alarm clocks, USB chargers and plug adapters, air purifiers, televisions, picture frames, ornaments and vents. In bathrooms, check extractor vents, baskets, hooks and fittings facing the shower. Unexplained gifts deserve particular attention.
Can a hidden camera be found if it is switched off? Not by an RF detector, which only finds devices that are transmitting. But a lens reflects light whether the camera is powered or not, so an optical check with a lens finder — and a careful physical search — will find a camera that a radio sweep misses.
Is it legal to check my own home for cameras? Yes. Inspecting a space you live in for surveillance devices is entirely lawful. What is restricted across Switzerland and the EU is covertly recording other people without their consent, which is the offence being committed against you if you find one.
