Hidden Cameras in Bedrooms and Bathrooms: The 15 Spots to Check in Every Rental

If someone hides a camera in a rental, a hotel room, or even a changing area, it goes where people are most private. Bedrooms and bathrooms are the two rooms that matter most in a sweep — and they are also the rooms where a quick, calm check finds most problems. Here are the hiding spots that show up again and again, plus a five-minute routine for checking them.

Start with the obvious: anything with a lens

Hidden cameras need a line of sight. Stand where a person would be most exposed — the bed, the shower — and ask: what is looking back at me? Anything with a dark dot, a pinhole, or an odd glossy circle on a matte surface deserves a closer look.

The 15 spots to check

1. Smoke detectors and CO alarms. The most cited hiding spot for a reason: they sit high, face the whole room, and nobody questions one. Compare it to detectors in other rooms of the same property — the odd one out is worth a photo.

2. Alarm clocks and bedside radios. A camera lens can hide inside the dark speaker grille or the display. If the clock looks bulkier than it needs to be, take a closer look from the side.

3. USB chargers and power adapters. Oversized chargers, especially ones with a glossy front face that has no business being there, can hold a pinhole lens. Unplug and inspect any charger that feels heavier than it should.

4. Bedside lamps and reading lights. Check the base and any decorative elements facing the bed — a lens can hide in a screw cap or ornament.

5. Air vents and wall vents. Shine your phone flashlight through the slats; a lens will glint.

6. Bathroom exhaust fans. Same trick through the grille. They face the shower, which makes them high-value.

7. Shower heads and faucets. Uncommon, but hollow fixtures have been documented as hiding spots. Look for a lens behind the spray plate.

8. Shampoo, soap, and lotion dispensers. Wall-mounted dispensers with a facing side can conceal a lens in the cap or body. Pick them up and look from the side they face.

9. Mirrors. The old "fingertip test" — press a fingertip to the glass; if there is no visible gap between your finger and its reflection, it may be a two-way mirror with a camera behind it. Treat this as a screening test, not proof: lighting and mirror type affect the result, so a suspicious mirror deserves a physical check behind it if you can.

10. TV and set-top boxes. A camera can sit behind the TV's bottom bezel facing the room, or inside a fake cable box. TVs also conveniently justify a power cable.

11. Picture frames and wall art. Check anything hanging at bed or shower height, especially frames with thick backing or unusual glass.

12. Bookshelves and shelves. Cluttered shelves hide pinhole lenses easily. Run your eyes along each shelf edge at bed height.

13. Thermostats. A bulky thermostat with an extra dark window can house a lens alongside the temperature sensor.

14. Outlets and light switches. Replacement outlet covers with pinholes exist and look almost identical to real ones. Look at outlets facing the bed or shower, not the floor.

15. Plants and decorative objects. Fake plants, vases, and knickknacks pointed at the bed get a second look — a real plant in a weird position is more suspicious than a tidy one.

The five-minute routine

1. Lights-off lens sweep. Turn off the lights, close the curtains, and slowly sweep your phone flashlight across the room. Camera lenses often glint with a blue or green reflection. This catches the low-hanging fruit.

2. Magnetometer pass. A magnetic-field scan (the kind built into Hidden Camera Detector Pro) can flag electronics hidden inside objects that look inert — a "detector" that shows an anomaly deserves a visual check. Remember the limit: no app can guarantee finding every device, and some cameras emit no detectable signal at all.

3. Network scan. A Bluetooth and Wi-Fi scan shows every wireless device nearby. Your own phone, the TV, and the smart speaker are noise — the question is what you cannot account for. Anything unknown with a strong signal right next to you is worth identifying.

4. Physical check of the top five. Pick the five highest-value spots above — smoke detector, alarm clock, USB chargers, bathroom fan, mirror — and inspect them hands-on.

If you find something

Don't pull it down. Photograph and video it from several angles first, note the time, and leave the room. Then report it: to the property's management or the booking platform, and to local police. Documenting before touching matters — the device may be evidence.

Check before you relax

A bedroom and bathroom sweep takes five minutes and gets easier every time you do it. Make it part of your arrival routine, right after you lock the door.
