Knowing how to check if a room has cameras using a phone can help you identify visible or potentially hidden recording devices when you are concerned about your privacy. A phone can help detect some cameras, but it cannot reliably identify every hidden camera. Some devices may be switched off, use wired connections, or be designed to avoid detection.
Look Around the Room Carefully
Start with a visual inspection before using your phone.
Pay particular attention to objects positioned where a camera could have a clear view of the room, such as smoke detectors, clocks, chargers, light fittings, air vents, or decorative objects.
Check unusual or unfamiliar objects
Look for tiny holes or lenses
Examine objects facing beds, bathrooms, or other private areas
Look for recently installed devices
Use Your Phone’s Camera to Look for Infrared Light
Some night-vision cameras use infrared LEDs that may be visible to a smartphone camera.
In a darkened room, open your phone’s camera and slowly scan suspicious areas. Some infrared lights may appear as small bright or purplish spots on the screen.
Turn off or reduce the room lighting
Open your phone’s camera
Scan suspicious objects
Look for unusual points of light
Not all phones can detect infrared light, and not every hidden camera uses infrared illumination.
Check for Unusual Reflections
A camera lens can sometimes create a small, distinctive reflection when light is directed toward it.
Use your phone’s flashlight and slowly inspect suspicious objects from different angles.
Turn on your phone’s flashlight
Shine it towards suspicious areas
Look for small lens-like reflections
Inspect anything that appears unusual
A reflection alone does not prove that a camera is present.
Check the Wi-Fi Network
If you have permission to access the room’s Wi-Fi network, you can use a network-scanning app to see which devices are connected.
Look for unfamiliar devices, although identifying a camera from a device name alone can be difficult. A camera may also use a different network, mobile data, or a wired connection.
Connect to the room’s Wi-Fi
Review connected devices
Look for unfamiliar devices
Investigate suspicious devices carefully
Use a Hidden-Camera Detection App Carefully
Some phone apps claim to detect hidden cameras using the phone’s magnetic sensors, network information, or camera.
These apps can sometimes be useful for an initial inspection, but their results are not always reliable. Avoid treating every alert as proof that a camera exists.
Use reputable apps
Check what detection method the app uses
Treat alerts as indications rather than confirmation
Inspect Suspicious Devices Without Damaging Them
If you notice an unfamiliar device, avoid breaking, disconnecting, or dismantling it.
Take photographs of the object and note where you found it. If you are in rented accommodation, a hotel, workplace, or another property you do not own, damaging equipment could create additional problems.
Photograph suspicious objects
Record their location
Avoid damaging property
Report serious concerns through the appropriate channel
Protect Your Privacy
If you discover what appears to be a hidden camera in a private area such as a bedroom or bathroom, prioritize your safety and privacy.
If appropriate, leave the area and report the suspected device to the property manager, accommodation provider, security personnel, or relevant authorities.
