Hidden Cameras in Hotels and Changing Rooms: Simple Ways to Protect Your Privacy
Privacy Alert: A hotel room, rental accommodation or changing room is supposed to be a private space. Yet the growing availability of extremely small surveillance devices has created a new concern for travellers and shoppers: hidden cameras placed inside ordinary-looking objects.
A camera can be difficult to notice when it is concealed inside a clock, smoke detector, decorative item, electrical fitting or another object. Recent reports have again highlighted why people should remain alert without becoming unnecessarily suspicious of every device around them.
Why Hidden Cameras Are Difficult to Spot
Modern miniature cameras can be remarkably small. Some may operate through Wi-Fi, while others can store recordings locally. Certain models can also use infrared illumination, which may not be visible to the naked eye.
The biggest warning sign is not necessarily the size of an object but its position and purpose. An unfamiliar device that has a direct view of a bed, shower, dressing area or changing space deserves particular attention.
Common places worth visually checking include:
- Smoke detectors
- Wall clocks and alarm clocks
- Lamps
- Photo frames
- Air vents
- Television units
- Electrical sockets and adapters
- Decorative objects
- Unfamiliar electronic equipment
These locations are not proof of surveillance by themselves; they are simply places where a person can perform a reasonable privacy check.
The Flashlight Test
One of the simplest checks involves a phone’s flashlight.
Turn off unnecessary lights and slowly move the flashlight across suspicious objects. A camera lens can reflect incoming light and may appear as a tiny bright spot.
This technique is useful as an initial inspection, but it cannot guarantee that a room is camera-free. A camera may be positioned differently, switched off, or designed in a way that makes detection more difficult.
Your Smartphone Can Also Help
A smartphone camera can sometimes reveal infrared light produced by certain cameras. In a darker room, slowly point the phone’s camera toward suspicious areas and watch for unusual bright spots.
However, smartphone cameras differ considerably. Some phones filter infrared light more effectively than others, so this should be regarded as an additional check rather than definitive proof.
Check Unfamiliar Network Devices
Some surveillance cameras connect to Wi-Fi. If you are using a property’s network, examining connected devices can occasionally reveal unfamiliar equipment.
A device identified as an IP camera or another unexpected network device may deserve investigation.
But an unknown device does not automatically mean there is a hidden camera. Hotels and rental properties can have many legitimate connected devices, including routers, smart televisions, printers and security equipment.
Don’t Rely Completely on the Mirror Test
The so-called fingertip test is often recommended for checking mirrors. It involves touching a finger to the glass and examining the reflection.
While it may encourage people to inspect a suspicious mirror more carefully, it is not a scientifically reliable way to establish whether a mirror is two-way. The construction of the mirror and the distance between its reflective surface and the glass can affect what you see.
If a mirror appears unusual or has unexplained equipment behind it, a closer physical inspection by the property manager or authorities is more meaningful.
What If You Actually Find Something Suspicious?
This is where people should be particularly careful.
Do not immediately dismantle, destroy or repeatedly handle the device. If it could be evidence of unlawful surveillance, disturbing it may complicate an investigation.
Instead:
- Move yourself to a safe location if necessary.
- Photograph the suspicious object and its surroundings.
- Note exactly where it was located and what direction it was facing.
- Inform hotel or property management.
- If you believe someone may have been secretly recorded, contact the police or appropriate authorities.
- Preserve booking records, messages and other relevant information.
The important distinction is between something that looks unusual and something that has actually been established as a camera. Let qualified personnel determine what the device is.
Changing Rooms Require Extra Vigilance
Changing rooms and trial areas deserve particular attention because people have an especially strong expectation of privacy there.
Before changing, take a few seconds to look around. Check unusual holes, unfamiliar fixtures, newly installed objects and anything apparently positioned to obtain a direct view of the changing area.
A quick inspection does not need to become an elaborate investigation. The goal is simply to notice something genuinely out of place.
Technology Is Evolving Too
Detection technology is advancing alongside miniature surveillance technology. In 2026, researchers demonstrated SweepLED, a prototype designed to use multiple LEDs and AI-based processing to identify hidden-camera lens reflections. Its researchers reported finding test cameras 94% of the time within five seconds per object, although the technology is currently a research prototype rather than a universally available consumer solution.
That development illustrates an important point: detecting tiny cameras is becoming a technological challenge of its own.
A Practical Privacy Routine for Travellers
You don’t need to spend hours inspecting every hotel room.
A sensible routine can be:
First: Look around the room when you arrive.
Second: Pay attention to unfamiliar objects facing private areas.
Third: Use a flashlight to inspect suspicious holes and surfaces.
Fourth: In a dark room, try the phone-camera infrared check if your phone supports it.
Fifth: If something genuinely suspicious appears, document it rather than immediately touching it.
Sixth: Report the matter to management and authorities when appropriate.
This approach provides a balance between privacy awareness and common sense.
Privacy Should Come Before Convenience
People should be able to change clothes, sleep, bathe and stay in temporary accommodation without fearing that their private activities are being secretly recorded.
At the same time, not every smoke detector, router or electronic device is evidence of surveillance. The safest approach is therefore awareness without panic.
A few minutes of sensible checking when entering an unfamiliar private space can provide additional peace of mind. And if something truly suspicious is discovered, preserving evidence and involving the appropriate authorities is far more effective than attempting to investigate or dismantle the device yourself.
Final Takeaway
Hidden-camera concerns are fundamentally about privacy and personal safety. Visual inspection, flashlight checks and appropriate smartphone tools can help identify suspicious equipment, but no single technique is guaranteed to find every device.
The strongest protection is awareness: know what belongs in the room, notice what looks out of place, and take suspicious discoveries seriously without jumping to conclusions.
