How to Detect a Hidden Camera Using Android Camera

If you suspect you're being watched via a hidden camera somewhere in your house or private space, your Android phone is a useful tool for detecting certain types of surveillance equipment. Although not foolproof, it's possible to use your Android phone's camera and magnetometer sensor to detect hidden cameras and microphones or other listening devices.

Some hidden cameras emit IR (infrared radiation) light, which isn't visible to the naked eye. The camera lens on your Android phone will pick up infrared light if you hold your device close enough. If you find a hidden camera that emits IR, it will appear in your camera's display as bright blue-white light.

Launch your phone's camera app.
Go around the room and point your phone's camera in areas you suspect spy equipment is hidden.
If you spot any small, bright-whitish light, set your phone down and investigate further. It may be a hidden camera.

How to Detect Hidden Cameras and Listening Devices by Scanning Wi-Fi

It's possible for some lower-end spy cameras and listening devices to show up in your phone's list of Wi-Fi connections. Refresh your network list as you walk around the room and look for any odd-looking connections or devices.

Your phone will most likely pick up several wireless devices and networks. Look for specific brand names or the word cam, camera, or similar.

Open the Settings app and then tap Network & internet.
Tap Wi-Fi.
Move your phone around and watch the list of nearby Wi-Fi networks.
That's it!
