Spy camera detector
🕑 Added 2024-01-02 03:09:53 +0000 UTCThis is a rather net version of the classic device used for locating hidden cameras in accommodation or other locations.
It relies on retro-reflection from optical systems to show their location and allow further investigation.

Interesting. I guess that could be kind of effective with the caveats you mentioned. I haven't heard dichroic filters mentioned since my early days in Television. I remember a dichroic filter was used in front of the prism that separated out the RGB tubes.

It will reflect off any typical optical system regardless of whether it is powered or not.

I take it that this will detect cameras that are not turned on at the time.
