Using a cell phone to detect a camera’s location is a relatively simple task. It requires an iPhone or a cell phone with an Android operating system. Either of these options will be more than enough. (1)

Detecting a hidden camera

This type of application is used by simply pressing a button. When this application starts to operate, infrared is triggered.

This operation is performed explicitly to detect the place where this infrared bounces. It occurs in cases where there are no hidden cameras anywhere. Implemented cameras invisible to the human eye can be seen regardless of the hidden camera lens size.

What to do with a detected camera?

Making a call close to the hidden camera can provide a signal. Some interference from the remote object should be heard.

The persomustto repeatedly moves closer and further away from the object to tdetect this interference clearly and accurately. 

There is no built-in LED light to indicate whether the camera is working. It will be instrumental in putting something in the middle of the camera to avoid video or photo recording. (2)

Other Ways to Detect a Camera with A Cell Phone

Use your cell phone to detect all wireless networks available in the same area. The wireless network used by the camera will be seen immediately. It could indicate that the camera is hidden in a room or elsewhere.

People can also take a picture where they think a hidden camera is working. The camera flash should be on, and the photo should be taken close up at the hidden camera’s possible location. It can provide a clear picture to see a camera lens somewhere through the reflection.
