It happens in a split second. You’re in a stall at a rest stop or a mall, and you see a tiny, unnatural glint of light reflecting off a coat hook. Or maybe it’s a smoke detector that looks just a little too "new" for a building this old. That sinking feeling in your gut isn't just paranoia anymore; it’s a rational response to the very real rise of the spy cam in public toilets. Honestly, it's a nightmare scenario that has moved from the realm of urban legends into police blotters worldwide.
Technology has gotten scary small. You can go on any major e-commerce site right now and buy a 1080p camera disguised as a screw head for under $30. Because these devices are so cheap and accessible, voyeurism has become a digital-age epidemic. But before you vow to never use a public restroom again, you need to know how these things actually work and where people hide them. It’s not about living in fear. It’s about being observant enough to reclaim your privacy.
Where the Spy Cam in Public Toilets is Usually Hiding
People are predictable, even the creeps. They want the "best" angle, which usually means eye-level or pointing directly at the toilet. If you’re looking for a spy cam in public toilets, don’t just glance at the floor. Check the "utilities."
I’m talking about things that belong in a bathroom but look slightly off. A common one is the dual-hook clothes hanger. You’ve seen them—the plastic ones that stick to the back of the door. If there’s a tiny hole at the top of the plastic molding, that’s where the lens sits. Another favorite for bad actors is the "dummy" air freshener. These are often battery-powered and can record for hours on a single charge.
Then there’s the high-tech stuff. Motion sensors and smoke detectors are perfect covers because we’re trained to ignore them. In 2023, there were several high-profile cases in South Korea—a country that has struggled immensely with molka (hidden camera filming)—where cameras were found inside the heads of tiny screws holding the stall partitions together. It sounds like a Bond movie, but it's just a cheap CMOS sensor and a microSD card.
The Physical Search: A Quick Checklist
Don't spend twenty minutes sweeping the room like a forensic investigator. Just do a five-second scan. Look for wires where they shouldn’t be. Most "spy" gear is wireless now, but some still need power if they're meant to stay there long-term. Look for asymmetrical holes. If a device has two small holes and one looks like a lens while the other looks like a microphone, that’s a red flag.

Touch things. If a plastic hook feels loose or wobbly, or if an air freshener doesn't actually smell like anything and feels heavy for its size, investigate. Some people use the "fingernail test" on mirrors to see if they are two-way, though in public toilets, it's much more common to have a physical camera hidden in an object than a complex two-way mirror setup.
The Tech You Can Use to Fight Back
You’ve probably heard that you can find a spy cam in public toilets just by using your phone’s flashlight. That's mostly true. Camera lenses are made of glass, and glass reflects light differently than plastic. If you turn off the lights—which isn't always possible in a public restroom—and shine a light around, a lens will often give off a blue or purple glint.
But let’s talk about apps. There are "hidden camera detector" apps that claim to use your phone's magnetometer to find electromagnetic fields (EMF). They're hit or miss. Mostly miss. Most small cameras don't put off enough EMF to trigger a phone sensor unless you're practically touching it.
A better way is checking the Wi-Fi. If you’re in a private or semi-private bathroom (like a single-stall "family" restroom), pull up your Wi-Fi settings. If you see a weird string of numbers and letters like "IPC-7722-X," that might be the camera’s local broadcast ID. Many of these devices create their own mini-network so the owner can download footage from nearby without touching the camera.
- Turn off the lights if possible.
- Use a dedicated RF (Radio Frequency) detector if you’re a frequent traveler; these handheld devices beep when they pick up a transmitting signal.
- Use your phone's front-facing camera (which often lacks an IR filter) to look for the tiny red glow of infrared lights used for night vision.
The Legal Reality: It's a Felony, Mostly
If you find a spy cam in public toilets, you are looking at a crime scene. In the United States, video voyeurism is covered under both state laws and the Federal Video Voyeurism Prevention Act of 2004. This law specifically prohibits the intentional capture of an image of a private area of an individual without their consent, under circumstances where the individual has a reasonable expectation of privacy.

And let’s be clear: a toilet stall is the gold standard of "reasonable expectation of privacy."
In the UK, the "upskirting" law passed in 2019 expanded protections, but general voyeurism has been a serious offense under the Sexual Offences Act 2003 for a long time. The penalties aren't just a slap on the wrist. We're talking jail time and being placed on a sex offender registry.
The problem is the "who." Finding the camera is easy compared to finding the person who put it there. Often, the footage is stored locally on an SD card, meaning the person has to come back to get it. If it's streaming to the cloud, the digital trail is better, but many of these devices use cheap, offshore servers that don't cooperate with local police.
What to Actually Do if You Find One
Stop. Don't touch it. I know your instinct is to rip it down and smash it or take it with you. Don't. You'll smudge fingerprints that might be on the casing or the SD card inside.
First, take your own phone out and take photos and video of the device in situ. Show exactly where it is hidden. Then, leave the stall and find a manager or security. If you’re in a government building or a park, call the non-emergency police line immediately.

Whatever you do, don't just walk away and post it on TikTok. While the "clout" might feel good, you’re potentially alerting the perpetrator to go and retrieve the evidence before the police get there. Treat it like a serious crime, because it is.
Real-World Cases That Changed Things
We saw a massive shift in public awareness after the 2018 scandals in various hotel chains and the 2021 reports of "hook cameras" in Florida beach restrooms. These weren't isolated incidents; they were organized efforts. In many cases, the perpetrators were caught because they were "regulars" who the staff eventually noticed hanging around the restrooms too often.
It’s also worth noting that this isn't just a "creep in the bushes" thing anymore. Sometimes, it’s employees. In a few documented cases, janitorial staff or maintenance workers used their access to install long-term surveillance. This is why many corporations have started implementing "sweeps" of their restrooms as part of their standard security protocol.
Actionable Steps for Your Safety
- Trust your "ick" factor. If a bathroom looks like it has too many gadgets, or if there’s a random USB wall charger plugged into an outlet near the floor, leave. There is no reason for a USB charger to be in a public toilet stall.
- The "Cover-Up" Method. If you suspect a hole might have a camera but you aren't 100% sure and just need to use the facilities, hang your coat or bag over it. Drape a piece of toilet paper over any suspicious "sensors."
- Report the small stuff. If you see a small hole drilled into a partition between stalls (the classic "glory hole" or just a peephole), report it to management. These are often precursors to or substitutes for cameras.
- Travel with a small flashlight. A high-lumen LED flashlight is better at catching lens reflections than your phone's weak LED.
- Spread awareness, not panic. Tell your friends what to look for—specifically the "clothes hook" and "smoke detector" models. The more people know what these look like, the less effective they become.
If you encounter a device, the most important thing is to maintain the integrity of the evidence. Call the authorities. Your discovery could prevent dozens of other people from being victimized by the same person. Privacy is a right, not a luxury, and keeping an eye out for a spy cam in public toilets is unfortunately a necessary part of modern life.
Stay observant. Check the hooks. If it looks like a lens, it probably is.
