Do you have experience with "infrared camera detection" on mobile devices?
Do you have experience with "infrared camera detection" on mobile devices?
If so, how do you assess the difference between o How the infrared camera detection works on a mobile device, versus o Similar functionality, in almost _any_ digital video camera viewfinder? Note this question is only about the inherent infrared detection differences between almost any digital camera ... and these "green-screen" viewfinder apps. Today I decided to check an area for hidden cameras and microphones where the first non-obnoxiousware non-Internet non-GPS-aware free tool I happened to test was o Detect Hidden Camera, version 1.9 o (com.techno95.detecthiddencameraandmicrophone) The way "it" works is pretty simple, apparently, where o It detects rf emitters using the magnetometer reading, and o It detects infrared emitters using a "green screen" video viewfinder Based on an Internet search, these tools abound on both iOS & Android: https://knowtechie.com/smartphone-apps-can-help-detect-hidden-cameras-anywhere/ https://www.techzac.com/best-hidden-camera-detector-apps-android/ http://www.graphictunnel.com/2017/09/best-hidden-camera-detector-apps.html etc. My question for this newsgroup is only about that green-screen viewfinder. Q: Essentially, other than being "green" - how is it any different from almost _any_ digital video viewfinder (all of which seem to detect infrared emissions)? |
