#App to detect hidden mini-cameras

“During the scan process, the ToF sensor emits laser pulses and receives the reflected light off of the object – such as the water bottle – and its surroundings. Specifically, the hidden camera embedded in the object reflects the incoming laser pulses at a higher intensity than its surroundings due to an effect called lens-sensor retro-reflection,” they explained.

“This occurs when almost all light energy impacting an object is reflected directly back to the source. These unexpectedly high-intensity reflections from hidden cameras cause certain regions of the ToF sensor to be “saturated” and appear as black pixels. LAPD processes these saturated areas to automatically identify the hidden camera and its location and displays it on the user’s smartphone screen.”
