How to Detect Hidden Cameras in Hotels and Changing Rooms

Three hotels in Goa. Two Airbnb apartments in Jaipur. A chain clothing store's trial room in Hyderabad. A homestay in Munnar. All in the first two months of 2026. All discovered to have hidden cameras pointed at guests in private spaces. Those are just the ones that made the news.

I've been following these cases for years now, and it still makes my blood boil that the hospitality industry treats this as a PR problem to be managed rather than a safety crisis to be solved. A hotel chain issues a statement expressing "deep concern." A retailer suspends the employee who installed the device. The police file an FIR. And nothing structurally changes. No mandatory inspection protocols. No standardized sweeps before check-in. No industry body stepping up with certification that a property is surveillance-free. Nothing. You're on your own.

So fine. If the industry won't protect you, you'll protect yourself. Here's everything I know about finding hidden cameras in spaces where you're supposed to have privacy.

The Devices You're Looking For

Spy cameras in 2026 are disturbingly small. We're talking about lenses the size of a pinhole — literally 1 to 2 millimeters in diameter — attached to circuit boards thinner than a credit card. Some run on built-in batteries that last 4 to 6 hours. Others draw power from the room's electrical wiring, which means they can record indefinitely. Some store footage on micro SD cards that the perpetrator retrieves later. Others connect to Wi-Fi and livestream to a remote server or phone.

The places where people hide them are predictable because the angle matters. A camera is useless unless it's pointing at the right spot — usually a bed, a shower, or a changing area. So the hiding places tend to be:

Smoke detectors and fire sprinklers on the ceiling. These are the classic spots. A camera behind the perforated cover of a smoke detector has a direct overhead view of the room. Hotels have these in every room, so they blend in perfectly. The thing is, if you look closely, a real smoke detector has a specific internal structure. A modified one might have a tiny dark spot — a lens — that shouldn't be there.

Electrical outlets and power adapters. Particularly the ones near beds or dressing tables. A camera can be embedded behind the face of a power socket or inside a phone charger that's plugged into the wall. I've seen cases where a regular-looking USB charging brick — the kind every hotel room has now — concealed a pinhole camera. If there's a charger or adapter in the room that you didn't bring, be suspicious.

Wall clocks, picture frames, and decorative objects. Anything hanging on a wall at roughly eye level and facing the bed or bathroom entrance. A small lens behind a decorative element is extremely hard to spot with a casual glance.

Bathroom fixtures. Shower heads, ventilation grills, towel hooks, and even soap dispensers. Bathroom cameras are often battery-powered because running wires in a wet area is harder, which means they tend to be slightly bulkier. That's your clue — if a fixture in the bathroom looks newer or different from the rest, or if it's positioned oddly, take a closer look.

TV bezels and set-top boxes. A camera embedded in the border of a flat-screen TV or inside a set-top box casing has a clear sightline to the bed. Since you expect those devices to be there, you don't question them.

Detection Method One: Your Eyes

The most basic sweep is a visual inspection, and it works better than you'd think if you know what to look for. When you enter a hotel room or changing space, spend five minutes before you settle in. Don't drop your bags and crash on the bed. Walk around first.

Look for anything that's slightly off. An outlet that's not quite flush with the wall. A screw that's a different color from the surrounding screws. A tiny dark spot on a smoke detector that looks like it could be a lens. Any object in the room that seems newly installed or different from similar objects (two towel hooks in the bathroom, but one looks newer — why?). Decorative items facing the bed at weird angles. Air fresheners or tissue boxes positioned in locations that seem chosen for sightlines rather than convenience.

Check mirrors. There's been a lot of social media advice about the "fingertip test" for two-way mirrors — you place your finger against the mirror, and if there's no gap between your fingertip and its reflection, it might be a two-way mirror. This test isn't perfectly reliable, but it's a reasonable first check. If you're genuinely concerned about a mirror, turn off the room lights, cup your hands around your eyes, and press against the glass to look through. If it's two-way, you might be able to see what's on the other side when the room behind is lit.

The Smartphone IR Trick

This is probably the single most useful detection technique, and it requires zero special equipment. Many hidden cameras use infrared LEDs for night vision — they need to illuminate the room without visible light to record in the dark. Your phone camera can see infrared light that your eyes can't.

Here's how to do it properly. Close the curtains, turn off every light in the room, and wait a minute for your eyes to adjust. Open your phone's camera app and slowly scan the entire room through the screen. Infrared LEDs will show up as bright purple or white dots. Now — this is the bit most guides miss — use your front-facing camera, not the rear one. Most modern smartphone rear cameras have an IR filter that blocks infrared light. Front-facing cameras usually don't have this filter, or have a weaker one. Test yours right now: point your TV remote at your front camera, press a button, and see if you can see the IR emitter light up on screen. If yes, your front camera will work for this.

Scan everywhere. Ceiling fixtures, electrical outlets, any small device in the room, the TV area, bathroom vents. A single glowing dot where there shouldn't be one is a red flag. That said, some devices don't use IR, especially those designed only for daytime recording. So this technique isn't perfect.

The Flashlight Method

Camera lenses, no matter how tiny, reflect light in a specific way. Grab the brightest flashlight you have — your phone's torch works fine — and shine it slowly across every surface in the room. You're looking for a small, bright, pinpoint reflection that's different from the reflection off paint, metal, or glass. Lenses have a distinctive bluish or reddish glint. Sweep the beam across smoke detectors, outlets, shelves, any objects facing the bed or bathroom.

Do this with the room lights off for best results. The contrast between your flashlight and the dark room makes lens reflections stand out sharply. It's tedious, but it works. I've heard of people finding cameras in hotel rooms this way that they'd completely missed during their visual scan.

Wi-Fi Network Scanning

Lots of modern spy cameras connect to the room's Wi-Fi network to stream footage to the person monitoring them. That connection shows up on the network, and you can find it.

Download a network scanning app. Fing is the most popular one; it's free and available on both Android and iOS. Connect to the hotel's Wi-Fi, open Fing, and run a network scan. The app will list every device connected to that network — phones, laptops, smart TVs, and anything else. You're looking for devices that seem unusual: entries identified as "IP Camera," "ESP32" or "ESP8266" (common microcontroller boards used in cheap spy cameras), devices with manufacturer names you don't recognize, or devices with no hostname at all.

Limitations here. Not all cameras use Wi-Fi — SD card-based cameras operate offline and won't show up in a network scan. And in a hotel with shared Wi-Fi, you'll see lots of devices from other guests, which makes it harder to identify something suspicious. But if you're in a private Airbnb or homestay with a dedicated Wi-Fi network, a network scan can be very revealing.

There's another angle to this. Turn off your phone's Wi-Fi and open the list of available networks. Some cameras create their own Wi-Fi hotspot — you might see a network name like "CAMERA_001" or a random string that doesn't match any network the property has told you about. That's suspicious.

RF Detectors and Lens Finders

If you travel frequently — especially if you're a woman traveling solo in India, because let's be honest about who's most at risk here — it's worth investing in a radio frequency detector. These are small handheld devices that sense electromagnetic signals emitted by wireless cameras, microphones, and GPS trackers. You wave them around the room, and they beep or light up when they detect a transmitting device.

You can find basic RF detectors on Amazon India for Rs 500 to Rs 3,000. The cheap ones have limited sensitivity and produce a lot of false positives from legitimate Wi-Fi devices and cell signals. Better ones in the Rs 2,000 to 5,000 range have adjustable sensitivity and can differentiate between different signal types. A few models combine RF detection with a lens finder — a ring of red LEDs that you look through while scanning; camera lenses show up as bright reflective points through the lens finder even when the camera is powered off.

Are these foolproof? No. A camera recording to an SD card with no wireless connection won't emit RF signals. A wired camera powered off the room's electrical circuit might not either. But for the majority of devices that use Wi-Fi or Bluetooth to transmit footage, an RF detector gives you a solid chance of finding them.

Trial Rooms and Changing Areas

Retail store trial rooms are a separate category of risk. You've got less time, you can't turn off the lights, and the space is small. But the approach adapts. When you enter a trial room, do a quick scan of the walls and ceiling for anything that looks like a lens or sensor. Check hooks, air vents, and mirrors. Run the flashlight test if the lighting is dim enough. Look at any electrical fixtures — an exhaust fan in a trial room with a tiny dark spot in it is worth questioning.

The most vulnerable trial rooms are the ones with poor construction — gaps in wall panels, exposed ceiling tiles, or mirrors that aren't flush-mounted. If the trial room feels flimsy or has obvious places where a device could be concealed, consider whether you actually need to try on that outfit here, or whether you'd rather take it home and return it if it doesn't fit.

Airbnbs, Homestays, and the Trust Problem

The rise of Airbnb, OYO, and homestay platforms across India has created a new dimension to the hidden camera problem. In a branded hotel, there's at least a corporate entity you can hold accountable. In a privately listed Airbnb or a homestay where the owner lives in the adjacent building, the accountability chain is shorter and less formal. Airbnb banned indoor cameras globally in April 2024, which is something. But the enforcement relies entirely on guests discovering cameras and reporting them. The platform doesn't conduct physical inspections. They can't. They've got millions of listings worldwide, and the entire business model is built on hosts managing their own properties.

OYO properties present their own challenge. Many OYO-listed rooms are in budget hotels and guesthouses that have minimal security oversight. The branding gives an impression of standardization that the underlying property may not actually deliver. An OYO-branded room in a tier-2 city is typically a locally owned hotel room with a fresh coat of paint and a branded pillow cover. The technology infrastructure — whether the room has been swept for surveillance devices — is entirely up to the local operator.

Homestays in tourist areas — Goa, Kerala, Himachal, Rajasthan — operate in an even more informal space. The host might be a retiree renting out a spare room, or a property investor running multiple units through a management company. Regulations around homestay accommodations vary by state, and surveillance device inspection isn't part of any state's homestay certification process that I'm aware of. You're relying entirely on the host's integrity and your own vigilance.

For any non-hotel accommodation, the network scanning approach becomes especially useful. In a hotel with shared Wi-Fi, suspicious devices might be harder to identify in a crowd of connections. In a homestay with a single router and five to ten connected devices, a hidden camera's network signature stands out much more clearly. Make the Fing scan your standard check-in routine for any non-hotel stay.

If You Find Something

Don't touch it. Don't remove it. Don't unplug it. I can't stress this enough. Your instinct will be to rip it off the wall. Resist. The device is evidence. If you disturb it, you make prosecution harder.

Take photos and video of the device in place, from multiple angles, with something in the frame for scale (your hand, a coin). Note the exact location. Then leave the room and call the police. Dial 100 or go directly to the nearest police station and file an FIR. Under Section 354C of the IPC (voyeurism), the act of watching or capturing images of a woman in a private space is punishable with up to 3 years imprisonment for a first offense and up to 7 years for a repeat offense. The IT Act's Section 66E covers capturing and publishing private images without consent.

If you're in a hotel, alert the management only after you've documented the evidence yourself. Don't let them "handle it internally" — that's code for making it disappear. There have been cases where hotel staff removed cameras before police arrived, and without physical evidence, the case collapsed.

File a complaint on the National Cyber Crime Reporting Portal at cybercrime.gov.in as well. If you believe footage may have been recorded or distributed, consult a lawyer about your options under the DPDP Act and the IT Act. Some victims have successfully obtained injunctions against the distribution of recorded material.

An Industry That Refuses to Self-Regulate

The Federation of Hotel and Restaurant Associations of India has, to my knowledge, issued zero binding guidelines to its members about mandatory camera sweeps of guest rooms. Zero standardized protocols for inspection. Zero certification program that a guest can look for. The Ministry of Tourism hasn't mandated it either. Neither has any state tourism body.

We have safety certifications for fire, food hygiene, and structural integrity. We inspect elevators and swimming pools. But a hotel room where people undress, sleep, and have intimate moments? No inspection requirement for surveillance devices. Not one.

Airbnb added a global ban on indoor cameras in April 2024. That's a start. But enforcement depends on guests reporting violations, which means the burden is right back on you, the person paying for privacy you're not guaranteed to get.

I keep thinking about a case from December 2025 in Uttarakhand — a couple found a camera in a ceiling light fixture in a midrange hotel they'd booked for an anniversary trip. The hotel owner's response was that a "maintenance worker" must have placed it without management's knowledge. The police made an arrest. The hotel is still operating. Still listed on booking platforms. Still taking guests into that same room, presumably without the camera now but who actually verified that.

Nobody's coming to fix this. Take the five minutes and check the room yourself.
