How does a 'camera detector' (/hidden device detector) detect the hidden camera/device? (curious as to whether they give many false-positives when used in real settings, e.g. airbnb or hotel room).
- throwaway81523 9mo agoIt's an RF field strength meter. I watched about a half minute of the video then shut it off.

- vorpalhex 9mo agoRF or EMF detection, magnetic field detection and an IR light plus filtered lens for visually checking for camera lenses. Ye old k18 is still the $50 go to for foiling airbnb perverts.
