Room check
How to find hidden cameras in a hotel room or rental
To find hidden cameras, check the network first and the objects second. Scan the Wi-Fi for devices that offer video, darken the room and sweep slowly with a flashlight to catch the glint of a lens, look for faint infrared dots through your phone’s camera, then inspect anything that faces the bed, the shower or where you change. In a typical hotel room the whole check takes about 15 minutes.
Hidden cameras sold online are usually dressed up as ordinary things: USB chargers, alarm clocks, smoke detectors, picture frames. Each one still needs a lens with a clear view, a power source and, in most cases, a way to send video. Those needs are what you check for.
Quick steps
- Scan the Wi-Fi network. Join the room’s Wi-Fi and list the connected devices. Look for unfamiliar names, camera brands and devices that offer video streaming.
- Check nearby Bluetooth devices. Walk the room with a Bluetooth scan open and watch for a device whose signal rises as you approach one object.
- Sweep the dark room with light. Close the curtains, switch off the lights, hold your phone’s flashlight close to your eyes and move it slowly across each object. A lens returns a small, steady pinpoint.
- Look for infrared lights. Through your phone’s camera, look for faint purple or white dots in the dark, often arranged in a ring around a lens.
- Inspect objects that face private areas. Check smoke detectors, clocks, chargers, speakers, plants and frames that point at the bed, shower or changing area.
- Record what you find. Photograph anything suspicious before touching it and note where it is and the time.
Start with the network
Most cheap hidden cameras stream to an app over Wi-Fi, so the network is the fastest place to start. Connect to the room’s Wi-Fi and run a scan. You are looking for three things: names you don’t recognize, brands that make cameras, and devices that offer video streaming services such as RTSP or ONVIF.
Hotel networks often isolate guests from each other, which hides everything, including a camera. A rental’s home Wi-Fi usually doesn’t, so in an Airbnb you will see the host’s TV, speakers and router. That is normal. An unnamed device that offers video, in a flat with no disclosed cameras, is not.
Sweep the room with light
A camera lens is a small curved piece of glass behind a dark opening, and it reflects light straight back at its source. Close the curtains and switch the lights off. Hold your phone’s flashlight next to your eyes, not at arm’s length, so the reflection comes back toward you.
Move slowly across every surface at bed height and above. A lens shows as a tiny blue or white pinpoint that stays put as you shift your head slightly. Glitter, screws and glossy plastic sparkle too, so check each hit from a second angle and up close before deciding anything.
Check for infrared in the dark
Cameras that see in the dark use infrared LEDs, usually in a ring around the lens. Your eyes can’t see them, but many phone cameras can. Point a TV remote at your phone’s camera and press a button. If the screen shows a flashing light, your phone works for this check.
With the room still dark, scan slowly through the camera and look for faint purple, pink or white dots that don’t appear when you look directly. Try the front camera if the rear one shows nothing. Some phones filter infrared on one camera only.
Where to look in a hotel room
Put your time into objects with a view of the bed, the shower or where you would change. A camera pointed at a wall or a door is far less likely to be there for the reasons you are worried about.
- Smoke detectors, especially a second one in a small room or one mounted on a wall facing the bed
- Alarm clocks and speakers with glossy black fronts that can hide a lens
- USB chargers and adapters you didn’t bring, plugged in and facing the bed
- Picture frames, plants and shelves at bed height
- TVs, set-top boxes and routers, which already have power and a network
- Air vents and mirrors in bathrooms and changing areas
What to do if you find a hidden camera
Don’t pull it apart. Photograph it where it sits, note the time and, if you can, the device name from the Wi-Fi scan. Cover it or move to another room while you sort things out.
In a hotel, ask for the duty manager and request a different room. In a rental, contact the booking platform through its app, since recording inside a listing breaks both Airbnb and Vrbo rules. If the camera points at a bedroom or bathroom, call the local police. A dated record of what you saw, such as a PDF export of your room findings, helps with all three.
Questions
How long does it take to check a room for cameras?
About 15 minutes for a hotel room and 20 to 30 for a rental with several rooms. The Wi-Fi scan takes about 30 seconds; most of the time goes into sweeping each object with light in the dark.
Should I unplug a device I think is a camera?
Photograph it first, then unplugging is fine for a charger or clock you did not bring. Leave smoke detectors alone, because they are safety equipment. Ask staff or the host to inspect those instead.
