Traveling can be a thrilling experience, but it also comes with risks that might not be immediately obvious. One such risk is the possibility of hidden cameras. These devices can be placed in hotel rooms, rental properties, or even public spaces, capturing footage without your knowledge or consent. For travelers, it is essential to take precautions and remain aware of their surroundings.
Knowing how to protect yourself from hidden cameras while traveling is crucial for ensuring your privacy and safety. With technology advancing rapidly, it is becoming increasingly easier for these devices to blend in unnoticed. However, with a few simple steps and awareness, travelers can significantly reduce their risk of falling victim to such surveillance. Ready to protect your privacy? Here are 15 practical ways to keep yourself safe from hidden cameras on your next trip.
Scan the Room Upon Entry
When you first arrive, take a moment to settle in before unpacking. Walk around the room and pay close attention to objects that seem oddly placed, especially items that point toward beds, showers, or toilets. Look for tiny holes or black dots in clocks, picture frames, or vents. If something feels out of place or unnecessary, like a motion detector in the corner of a small bedroom, take a closer look. Trust your sense of space and symmetry. Most rental units have consistent decor—one oddly placed object should stand out. A slow, observant walk-through is your first layer of protection.
Turn Off the Lights and Use Your Phone’s Flashlight
Hidden lenses reflect light differently from regular surfaces. Turn off all the lights in the room at night, then slowly shine your phone’s flashlight across surfaces. Watch for tiny flashes or glints in objects like fire alarms, smoke detectors, or framed mirrors. A tiny glint may indicate the presence of a lens. This method is especially useful in bathrooms and bedrooms, where hidden cameras are often placed. Move your light source from different angles to catch any reflections that don’t belong. It’s a simple trick that takes less than five minutes and can reveal things not visible in normal lighting.
Use Your Phone’s Camera to Detect Infrared
Infrared (IR) lights, commonly used in night-vision cameras, are invisible to the naked eye but appear on digital screens. Switch your smartphone to video mode and scan the room in the dark. Slowly wave the camera across electronics, ceilings, and vents. Look for small pulsing lights or steady dots that glow white or purple on screen—these may be infrared signals. Try both front and rear cameras, as some are more sensitive to IR. While this method doesn’t detect every camera, it is particularly useful for spotting those that operate silently in low-light conditions.
Inspect Smoke Detectors, Clocks, and USB Chargers
Common objects, such as alarm clocks, wall chargers, or smoke detectors, are often used to conceal hidden cameras. If there’s more than one detector in a small space, or a clock is oddly angled toward the bed, take a closer look. Examine vents, screw holes, or areas where glass or plastic covers a small dot. Look for anything that points directly at high-privacy areas, such as the bed, shower, or toilet. If you can safely unplug a suspicious item, do so. Most hosts won’t mind a cautious guest, but if you see wires where they shouldn’t be, it’s worth asking questions.
Listen for Humming or Clicking Sounds
Some hidden cameras make faint operational sounds. Once the room is completely quiet—no AC, no TV—stop and listen. A soft hum, a subtle click, or a high-pitched buzz might be more than background noise. Check suspicious devices nearby. This method is especially helpful when trying to locate something in plain sight that is disguised as a charger, air purifier, or lamp. You won’t always hear anything, but in quieter areas with older or poorly disguised equipment, microphones or wireless components may emit slight noise. Trust your ears. If it doesn’t sound right, it may not belong there.
Check Mirrors for Two-Way Glass
A classic test can help identify whether a mirror might be see-through from the other side. Place your fingertip directly against the glass—if there’s a visible gap between your finger and its reflection, it’s likely a standard mirror. If the reflection touches your finger with no gap, it could be a two-way mirror. While rare, these have been used in inappropriate surveillance cases. Also, examine how the mirror is mounted. If it’s deeply set into the wall or placed where it seems unnecessary, it may be worth further inspection. Trust spatial logic—mirrors don’t usually face toilets withouta purpose.
Scan Wi-Fi Networks for Suspicious Devices
Hidden cameras often connect to local Wi-Fi to stream footage. Using a network scanner app like Fing, you can scan all devices connected to the same network. Look for unfamiliar items labeled as "IP Camera," "Cam," or with odd manufacturer names. Even unnamed devices may be suspicious if the number exceeds what you expect. If you see something connected that doesn’t match your phone, laptop, or TV, it’s worth investigating. While some devices may belong to the host, unrecognized entries can suggest hidden tech. Note down MAC addresses or take screenshots—you may need them for a report.
Cover Suspicious or Unused Devices
If you’re unsure about a device—be it a smoke detector, USB hub, alarm clock, or TV remote—cover it with a towel, shirt, sticky note, or tissue box. A covered camera can’t see. Use common sense: anything that seems overly positioned toward the bed, shower, or toilet might be worth blocking temporarily. Just be careful not to damage anything, especially in rentals. You’re not tampering—you’re shielding yourself. If you uncover something suspicious, document it. Take photos and alert the host or platform. It’s your right to set physical boundaries in the space where you’re expected to rest.
Unplug or Power Down Non-Essential Electronics

If you’re not using a TV, Bluetooth speaker, or oddly placed air purifier, go ahead and unplug it. Electronics that aren’t necessary for comfort or function don’t need to stay connected. You can also face devices toward a wall or slide them inside a drawer. If a clock appears oddly angled or a light fixture has ports you don’t recognize, turning it off eliminates any potential hidden recording. Make sure to take photos before unplugging if you’re worried about being charged. Most hosts won’t object to you unplugging something, especially if you plug it back in when you leave.
Use a Personal Hidden Camera Detector
Compact handheld detectors can help identify hidden lenses or radio frequencies emitted by surveillance devices. Some methods involve scanning for wireless signals, while others utilize red light reflection to locate hidden lenses. Sweep the room slowly, paying particular attention to areas around outlets, shelves, vents, and electronics. While these tools aren’t foolproof, they add an extra layer of confidence, especially in places where privacy feels uncertain. Many travelers keep one in their bag for peace of mind. If you plan to stay in Airbnb or budget accommodations frequently, a small investment in this tool can help you feel more secure in unfamiliar spaces.
Check Ceiling Vents and Wall Décor
Ceiling vents, fake plants, framed art, or hanging decorations can conceal tiny cameras if someone has tampered with the space. Pay attention to anything angled toward the bed, bathroom, or shower. A vent that looks out of place, has a shiny center, or appears oddly positioned may warrant a closer inspection. Some picture frames or clocks have hidden compartments or pinhole lenses. If you can safely move an item or shine a light into its surface, do it. Most decor is harmless, but items that appear freshly mounted or overly directed at private areas deserve extra attention.
Block the View With a Scarf or Towel
If you can’t remove or inspect a suspicious object, block its view. A scarf, hat, jacket, tissue box, or even furniture can help shield high-privacy zones, such as beds or showers. This can reduce your exposure while you investigate or decide on the next course of action. You don’t need special tools—just use what’s around you to obstruct any direct line of sight. Don’t worry about being overcautious. A camera can’t record what it can’t see. And if you find that the item in question isn’t a camera after all, no harm done—just remove the cover when you’re finished.
Use White Noise to Disrupt Microphones
Some surveillance devices include microphones, and while they’re harder to detect, you can take steps to reduce what they pick up. Use a phone app, fan, or white noise machine to create a steady background sound during private conversations. This won’t cancel everything, but it can reduce clarity and limit what’s understandable. Bathrooms, living rooms, and even changing areas are common spots where hidden audio might be placed. If you're especially concerned, speak outdoors or near a running faucet. In short-term rentals, especially those without clear security policies, it’s safer to assume that sound could also be recorded.
Review Host or Hotel Reviews Carefully
Before you book a room or rental, take a close look at past guest reviews—not just the five-star ones, but the two- and three-star comments. Scan for keywords like “privacy,” “camera,” “strange devices,” or “felt watched.” Sometimes, repeated complaints go unnoticed until they’re viewed together. People may also refer to suspicious clocks, alarms, or motion sensors. While one review may not be significant, three or more reviews that note similar concerns should raise concerns. Guests often pick up on patterns that hosts won’t advertise. Doing a little reading beforehand can spare you from walking into an uncomfortable or invasive situation.
Trust Your Instincts
If something feels wrong—whether it’s a light that won’t turn off, a device you didn’t notice before, or a lingering sense that you're being watched—don’t ignore it. Your surroundings and past experiences shape instincts for a reason. If your comfort drops or your awareness rises, listen to that. Take steps to recheck the space, move to a new room, or contact the host or front desk. If necessary, leave the property altogether and document the reason. You don’t need proof to make a change—you just need to feel safe. That’s always worth protecting.
Privacy First, Wherever You Go
Hidden cameras are an unsettling reality, but with the right precautions, they don’t have to ruin your travel experience. Staying vigilant, checking your surroundings, and using basic tools can go a long way in maintaining your privacy. Whether you're staying in a hotel, renting a vacation home, or simply visiting a new city, knowing how to spot and avoid these devices can ensure your personal space remains protected.
While it’s impossible to fully eliminate every risk, taking these steps can help you feel more secure while exploring the world. Don’t let hidden cameras compromise your peace of mind—be proactive, stay vigilant, and enjoy your travels knowing you’ve taken the necessary measures to protect yourself. Your privacy is worth the effort.
