Detection of infrared (IR) signals from remote controls and hidden cameras. The application through the camera is able to filter signals from remote controls, cameras and any other device that emits infrared rays. The sensitivity adjustment allows you to avoid or reduce false positives. Simply frame the area to be examined to immediately obtain in real time on the screen the possible source of IR emission with acoustic signal and graphic circumscription of the emission area on the screen. Better results can be obtained using an infrared filter costing a few dollars or a filter made by hand with a piece of a DVD from which the paint with the reflective layer must have been removed.
