How to Detect Hidden Cameras in Your Airbnb or Holiday Rental (Singapore Guide 2026)
The fastest way to find a hidden camera in your Airbnb is to turn off all the lights, use a lens detector (or your phone's front camera) to sweep the room, and check any object with a USB port or a small hole facing the bed or bathroom. In Singapore, the Voyeurism Act 2019 carries up to 2 years' jail — but that doesn't help you if the footage was already taken. Detection takes 10 minutes. It's worth those 10 minutes.
Over 1.5 million Singaporeans travel abroad every quarter. That's a lot of people checking into unfamiliar rooms — Airbnb apartments in Tokyo, guesthouses in Bali, service apartments in Bangkok, hotels in Batam that cost SGD 35 a night and come with suspicious wall clocks.
The Voyeurism Act 2019 made Singapore one of the toughest jurisdictions in Southeast Asia on this offence. Up to 2 years in prison, fines, and a sex offender registry listing. Great. But that law only helps you after the fact, and only if the perpetrator is caught. The footage still exists.
So let's talk about what actually protects you: knowing what to look for before you unpack.
Why Holiday Rentals Are Higher Risk Than Hotels
Hotels have guests checking in and out under CCTV, with staff who can be held accountable. A private Airbnb listing? The host has unsupervised access to the entire unit before your arrival.
Singapore's Airbnb market is heavily regulated — hosts need URA approval, and short-term rentals under 3 months in private residential properties were only recently permitted under strict conditions. That regulatory environment weeds out some bad actors. But once you cross the Causeway into JB, fly budget to Batam on Batam Fast, or board a Scoot flight to anywhere in the region, you're in jurisdictions with very different enforcement landscapes.
Japan has had multiple arrest cases involving Airbnb hosts installing cameras in bathrooms. Indonesia, Thailand, and Vietnam have all seen high-profile incidents. Even within Singapore, there have been cases of cameras found in rented rooms.
It's not paranoia. It's pattern recognition.
The Gear: What Actually Works
You don't need to spend a lot. But you do need the right tools.
RF (Radio Frequency) Detectors
Wireless cameras transmit footage via WiFi or RF. An RF detector picks up that signal. The catch: modern cameras increasingly use local storage (SD cards) and don't transmit anything — so RF alone isn't enough. Still worth having. A decent one runs SGD 40–80.
Lens Detectors (Optical / IR)
These are the more reliable option. They work by shining a patterned infrared light and picking up the characteristic reflection from a camera lens — even one that's completely powered off and not transmitting anything. The lens reflection is distinctive. A good lens detector in the SGD 60–120 range will catch lenses hidden inside smoke detectors, clock radios, USB chargers, and wall sockets.
Combined RF + Lens Detectors
If you're buying one tool, buy a combination unit. You get RF detection for transmitting cameras and optical detection for passive/storage-only cameras. This is what we'd recommend for frequent travellers — especially if you're doing 4–6 trips a year, which is not unusual for Singaporeans.
Your Smartphone (Free, Limited)
iPhone front cameras don't have IR filters — point your front camera at a TV remote and press a button; you'll see the IR LED flash. This works for very basic IR-emitting cameras. It won't catch lens reflections or RF signals. It's a backup, not a method.
The 10-Minute Check-In Sweep
Do this before you put your bag down. Seriously — before.
Step 1: Don't connect to the WiFi yet.
Some cameras activate when they detect a new device on the network. Connect to mobile data for this step.
Step 2: Look for anything with a small hole or lens-sized opening.
Clock faces. Smoke detectors. Air purifiers. USB wall chargers. Power banks on shelves. Picture frames facing the bed. Tissue boxes. Books with their spines facing the room. Anything plugged in that doesn't have an obvious function.
In Airbnb specifically, look for objects that seem slightly out of place — a smoke detector in a bedroom (unusual in many countries), a phone charger that wasn't in the listing photos, a plant pot facing the shower.
Step 3: Turn off all the lights.
Scan with your lens detector. Move slowly. Pay particular attention to anything at eye level or above — cameras placed high have wider field of view.
Step 4: Run your RF detector.
Walk around the room. Hold it near objects on your sweep list. An active transmission will spike the meter.
Step 5: Check the bathroom separately.
This gets its own step because it's the highest-risk space and people rush through it. Check the showerhead, soap dispensers, shampoo bottles (yes, really), wall vents, and any fixture that faces the shower or toilet directly.
Step 6: Check network devices.
If the host has a router or smart home hub in the unit, note the make and model. Some cheap "router" housings are camera enclosures. A legitimate router doesn't need to face the bedroom.
Objects That Have Hidden Cameras More Often Than You'd Think
Let's be specific, because "any household object" is useless advice.
- Alarm clocks — particularly digital ones with a small circular vent. This is probably the most common housing.
- USB wall chargers — pinhole lens in the charging port area. They charge your phone normally. They also record you.
- Smoke detectors — especially ones mounted in bedrooms. Check if it's actually hardwired or just sitting there with a USB cable running behind it.
- Air fresheners — the plug-in kind. Small, ignored, usually positioned at mid-room height.
- TV remote controls left on the table — rare but documented.
- Stuffed toys or decorative items — more common in family-listing Airbnbs, unfortunately.
- Mirrors — specifically, check if any mirror seems slightly further from the wall than usual. A two-way mirror will show your reflection and a dark room behind it. Hold a lit torch flat against the mirror surface; if you see a clear gap between your finger and its reflection, it may be two-way.
If You Find Something
Stay calm. Don't touch it.
Document everything first — photograph the object in situ, photograph its position in the room, note the time. This is evidence.
Do not move it, remove it, or confront the host directly at this point.
Leave the unit with your belongings. Contact Airbnb immediately through the app — use the Safety Issue category. If you're in Singapore, file a report with the Singapore Police Force (SPF). If you're overseas, contact the local police and the Singapore Embassy.
Under the Voyeurism Act 2019, filming someone in a private act without consent carries up to 2 years' imprisonment or a fine, or both. If you're the victim, you have legal standing to pursue this. Document everything for that purpose.
Airbnb's policy is to remove listings involved in confirmed camera incidents and issue refunds. Push for this through their resolution centre.
Travelling from Changi: A Word on Risk by Destination
Singapore's aviation hub status means we travel widely, and risk varies significantly by destination.
Japan: High standards, but there have been arrest cases specifically involving Airbnb hosts in Tokyo and Osaka. Japan also has issues with cameras in public spaces — onsen changing rooms, train station toilets. Vigilance in both.
Thailand (Bangkok, Phuket, Chiang Mai): Multiple documented incidents in short-term rentals. Budget accommodation in tourist areas carries higher risk. Always sweep.
Bali/Indonesia: Growing Airbnb market with variable quality control. The more budget the listing, the less scrutiny it's had.
Malaysia (JB, KL, Penang): Proximity means many Singaporeans treat JB as a weekend destination. It's close, but it's a different legal environment. Sweep anyway.
Vietnam: Rapidly growing tourism sector, less regulatory oversight on short-term rentals. Higher vigilance warranted.
South Korea: K-drama tourism is real and so are incidents in goshiwons and some Airbnb units. Don't skip the sweep because the neighbourhood looks upscale.
What to Buy, and What Not to Waste Money On
A few things to avoid:
Don't buy the SGD 10–15 "camera detectors" on Lazada. They pick up almost any IR source (including your TV remote, your phone charger brick, sunlight). They generate false positives constantly, which means you either trust them and find nothing, or you panic at everything. Neither is useful.
Don't rely on phone apps. "Hidden camera detector" apps that claim to use your phone's magnetometer to find cameras are largely ineffective. A camera lens is not magnetic. A WiFi-transmitting camera might show up on a network scan app, but that only catches one type.
What to buy:
A combination RF + optical lens detector in the SGD 80–150 range. Look for units from JMDHKK, Wicam, or similar dedicated security detection brands. We stock several at xxscam.com — the ones we carry have been tested against actual pinhole cameras, not just listed as "detects cameras."
If you travel more than 4–5 times a year, the investment pays for itself the first time you find something — or the first time you don't find anything and can actually sleep properly.
One Last Thing
Airbnb has a policy against security cameras in private spaces. Hosts are allowed to disclose outdoor cameras but cannot have any cameras in bedrooms, bathrooms, or sleeping areas. That's the policy.
Policy and practice aren't the same thing. The sweep is your practice.
Ten minutes per check-in. That's all it takes.
