Know Common Hiding Places for Hidden Cameras

Many hidden cameras are placed where they can capture the most activity discreetly. When inspecting, pay attention to:

  • Smoke detectors: Often mounted on ceilings with a good view of the room.
  • Clocks: Cameras can be hidden inside digital alarm clocks or wall clocks.
  • Air purifiers or speakers: These appliances have vents, providing room for tiny cameras.
  • Mirrors: A two-way mirror might have a camera behind it.
  • Lamps and light fixtures: Look inside lampshades or floor lamps.
  • Bookshelves or houseplants: Cameras can be tucked between decorations or leaves.

Physically Inspect Suspicious Items

Get up close to objects in the room. Some cameras may have:

  • Small lenses or glassy reflections: Shine a flashlight and look for reflective surfaces indicating a lens.
  • Wires that seem out of place: Hidden cameras need power or storage connections.
  • Holes in unexpected places: Look for pinhole-sized openings that could be camera lenses.

Pro tip: Take down objects like clocks or wall decorations to inspect behind them if they seem suspicious.

Use Your Smartphone Camera

Some cameras emit infrared (IR) light thatโ€™s invisible to the naked eye but detectable through a smartphone camera.

How to check:

  • Turn off the lights in the room.
  • Open the camera app on your smartphone.
  • Slowly pan the camera across the room. If a hidden camera is present, you may notice a small blinking light or glow.

Tip: For some phones, only the front-facing camera can detect IR light.

Scan for Wireless Signals

Most hidden cameras use Wi-Fi to transmit footage. You can use apps or scanning tools to detect unfamiliar wireless devices.

  • Wi-Fi Scanning Apps:
    Download network scanning apps like Fing or Wireshark to identify strange devices on your network.
  • How to Use:
    • Connect your phone to the same Wi-Fi network.
    • Run a scan to see all connected devices. Look for suspicious names or unfamiliar IP addresses.

Note: Hidden cameras might use standalone networks. Try disconnecting from Wi-Fi and scanning for Bluetooth signals too.

How to Use a Detector:

  • Turn on the RF scanner mode and move it around the room.
  • The detector will alert you if it finds a hidden camera signal.
  • In optical detection mode, the device can help you visually scan for camera lenses using red LED light.

Test Mirrors for Two-Way Glass

Some hidden cameras are placed behind mirrors that function as two-way glass. Hereโ€™s how to check if a mirror is suspicious:

Finger Test:
Place your fingertip against the mirror. If there is a gap between your finger and its reflection, the mirror is likely normal.
If no gap exists, the mirror could be two-way glass with a camera behind it.

Listen for Unusual Noises

Some hidden cameras make faint sounds when operating, especially those with mechanical parts like rotating lenses or servos.

How to check:

  • Turn off any noisy appliances and listen carefully.
  • Move through the room slowly and note any unusual sounds.

Turn Off the Lights to Spot LEDs

Many hidden cameras have tiny indicator lights. In a dark room, even small LEDs can be more noticeable.

How to check:

  • Turn off all lights and close the curtains.
  • Slowly scan the room for tiny, unusual lights or glows.

Check for Warm Spots

Some cameras, especially wireless ones, emit heat. You can use your hand or an infrared thermometer to feel for warmth in places where no heat source should be present.

Where to check:

  • Electrical outlets
  • Bookshelves
  • Air vents

Contact Authorities if You Find a Camera

If you do discover a hidden camera in a rental property, hotel, or public space, itโ€™s essential to document your findings.

  • Do not disturb the device more than necessary to gather evidence.
  • Take photos or videos of the camera and its location.
  • Report the incident to the appropriate authorities (hotel management, local law enforcement, etc.).
  • If staying at an Airbnb or rental property, contact the platform to file a report.

Final Thoughts

Hidden cameras are becoming harder to detect, but with the right tools and vigilance, you can protect your privacy. Knowing where to look, how to inspect devices, and using smartphone and network scanners can help you uncover even the most discreet surveillance equipment.

Being proactive in finding hidden cameras will ensure peace of mind, whether youโ€™re at home or traveling. Stay alert, stay safe, and act promptly if you find anything suspicious.
