Hidden cameras in hotel rooms follow a specific pattern. They're placed in spots that offer a continuous power source, a clear line of sight to beds or bathrooms, and a plausible everyday disguise. The good news: those patterns are well documented, and checking the right locations — methodically — takes under two minutes.
This guide covers the eight most common hiding spots identified in real reported cases, along with exactly what to look for at each one.
How hotel rooms differ from Airbnbs for detection
The detection approach for hotel rooms is slightly different from Airbnbs. Here's the key difference:
Wi-Fi network scans are less reliable in hotels. Most hotel networks use client isolation — a setting that prevents devices on the same network from seeing each other. This means a network scanner may not reveal a hidden camera even if it's connected to the hotel Wi-Fi. The technique that works well in Airbnbs has reduced effectiveness in hotels.
This makes the other two methods more important in hotels:
- Bluetooth detection — works regardless of network configuration
- Physical inspection — works on every camera, active or inactive, networked or not
The physical inspection is your most reliable tool in a hotel. It takes about 90 seconds and requires nothing but attention to the right locations.
The 8 most common hiding spots in hotel rooms
Smoke detectors
Highest riskThe most common location found in real cases. A smoke detector directly above the bed offers a bird's-eye view of the sleeping area, has a permanent power connection, and its position never seems unusual. Look for: a small hole or lens on the face that doesn't appear on a normal detector, unusual weight when handled, or a lens glint when you shine a torch at the unit from different angles.
Alarm clocks and clock radios
Highest riskBedside clock radios are a classic disguise. They face the bed by design, have a power outlet, and guests never think to move them. Check all four sides and the front face for small holes or lenses. A camera-equipped device is usually slightly heavier than a normal one. Also check: does the clock function normally? Non-functional electronics that are plugged in are a red flag.
USB chargers and power adapters
Highest riskSpy camera USB chargers look indistinguishable from standard phone chargers. They're sold openly online and are among the most affordable covert camera products available. Any USB charger or power adapter that was already plugged in when you arrived — and that you didn't bring — should be examined closely. Check the front face for a pinhole lens. Unplug and inspect from all sides.
Mirrors (particularly bathroom mirrors)
Medium riskTwo-way mirrors are real, and the test to identify them is straightforward. Press the tip of your fingernail against the glass surface. With a normal mirror, there is a visible gap between your fingernail and its reflection (because of the glass thickness). With a two-way mirror, there is no gap — your nail appears to touch its reflection directly. Use a torch to illuminate behind the mirror's surface from different angles.
Bathroom vents and exhaust fans
Highest riskBathroom vents offer a clear view of the most private area in the room while appearing completely unremarkable. Use a flashlight to illuminate inside the vent cover. Shine at different angles. A camera lens will produce a distinctive bright reflection — different from the surrounding plastic or metal. Most vent covers are removable with a gentle pull for a closer look.
Air purifiers and mini fans
Medium riskAny appliance with a grill or vent on the front face is a potential concealment point. Air purifiers are particularly common — the circular grill provides natural cover for a camera lens pointing outward. Inspect the front face closely. If the device produces no airflow or heat despite being plugged in, treat it as suspicious.
Picture frames and wall décor
Medium riskAny framed artwork or photo facing the bed is worth a second look, particularly if it has a dark border or a mount that could conceal a lens. Shine a torch at the frame from a few feet away — a lens will reflect the beam as a bright pinpoint glint distinctly different from the frame's surface. Check the back of the frame too — a camera module requires power, so look for a cable connection or battery compartment.
TVs and set-top boxes
Medium riskModern Smart TVs have built-in cameras and microphones — that's normal and expected. The concern is a separate device attached to or hidden behind the TV that shouldn't be there. Check the back of the TV unit and the connection panel for any device that wasn't factory-installed. Run a Bluetooth scan while standing near the TV — an unexpected BLE signal from the TV area is worth investigating.
Before you start the physical inspection, do a 30-second infrared check. Turn off the lights, switch to your phone's front-facing camera, and slowly pan across the room. Any device with active IR night vision will glow white or purple on screen. A TV remote pressed in front of the camera will show a glowing dot — that confirms the technique is working before you start.
How to check your hotel room systematically
-
1
Drop your bags, don't unpack yet
Do your sweep before settling in. It takes under 2 minutes and is easier when the room is still as you found it.
-
2
Run a Bluetooth scan
Open SafeRoom and run the BLE scan first. Any unexpected signals will appear within 30 seconds and give you a location to investigate during the physical check.
-
3
Dim the lights and do the IR sweep
Use your phone's front camera in a dark room to check for active IR emitters. Focus on smoke detectors, vents, and the TV area.
-
4
Follow the guided inspection
SafeRoom's 8-step checklist walks you through every location in order: smoke detector, mirrors, alarm clock, USB chargers, vents, picture frames, TV, and decorative items. Takes about 60 seconds once you're moving.
-
5
Save the scan report
SafeRoom automatically saves a timestamped report when the scan completes. If you find something later, the report documents your initial room state and is shareable with hotel management or authorities.
Do the full check in under 2 minutes.

What to do if you find something suspicious in a hotel room
Finding an unexpected device in a hotel room is alarming. Here's how to handle it without making the situation worse:
- Do not touch or move the device. Leave it exactly where it is for documentation and potential evidence.
- Photograph and video it from multiple angles, showing its location in the room and proximity to the bed or bathroom.
- Contact the front desk immediately and ask to change rooms. Request that management investigate. Document the name of the staff member you spoke with and the time.
- File a police report if you believe recording has taken place. Covert recording in a private space is a criminal offence in virtually every jurisdiction.
- Report to the booking platform if you booked through a third party. Include your SafeRoom scan report in the submission — it provides timestamped technical evidence of the device's presence.
Hotels, unlike Airbnb rentals, have different chain-of-command structures. If the front desk staff are unhelpful or dismissive, escalate to the duty manager and, if needed, go directly to local police. Do not leave the room until the device has been documented and witnesses have seen it.
