Using a cell phone to detect a camera’s location is a relatively simple task. It requires an iPhone or a cell phone with the Android operating system. Either of these options will be more than enough to rely on one of the applications used to detect any camera. (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?

It means that making a call close to where the hidden camera is located can provide a signal. During the week, some interference from the remote object should be heard.

The person needs to repeatedly move closer and further away from the object to clearly and accurately detect this interference. 

There is no built-in LED light to indicate whether the camera is working or not. 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
