#52Wonder if it handles the really tiny pinholes effectively. For now, a thermal camera feels more robust for peace of mind.
This detects cameras that are off, which a thermal camera would not.

#53Can't a thermal camera can do this? It should be able to detect any difference in ambient temp, even a few degrees, and a CMOS sensor gets warm, not to mention any wireless transmitters, power sources, and ICs. Turn off everything in the room and walk around with a ~$100 ali express handheld thermal camera.
LED clocks, alarm motion sensors, bluetooth speakers and whatever other appliances also get a bit warm. How would you tell a legit device from one with a milliwatt camera?

If you walk up to it and point the camera at it, you can see a lot of detail about what is going on in the device.
Here are some pictures of some ordinary electronics for reference:

#55People normally do this by scanning a 10mW 832nm laser with a mirror, according to Dan Gelbart in https://www.youtube.com/watch?v=0MtRxX0crjU . The lecture is 77 minutes, covering nonlinear junction detectors, digital calipers, the US-embassy bug in Russia, laser microphones bounced off windows, and geometric errors from material relaxation. The bit about camera detectors is close to the end. Works for eyeballs too.…
The junction detector is a truly brilliant idea that, unfortunately, is probably rendered nearly useless now that everything in the world has embedded electronics in it.
Also, thinking about it, you could probably defeat the optical retroreflection detector by putting the camera behind a Faraday rotator (optical isolator). But those are quite expensive and you'd need to be really paranoid to use one, plus it'll only really work well if you match the wavelength of the laser.

#56Finally, a practical use for those notification LEDs. Definitely adding this to my travel toolkit if it proves reliable.

#57Definitely trying this next time I check into an Airbnb. The old flashlight trick is tedious.

#59Earlier quoted context omitted.
For Meta they need to detect people giving wearers the finger to stop the glasses from recording or taking pics ha I do wear my Metas frequently though would never get the finger cause Im not a creep.
Our culture has definitely changed from when Google Glass wearers were referred to as Glassholes. It appears that more people have just accepted that they will be filmed anywhere and everywhere. I miss the old days.
Not everyone has accepted that.
Meta glasses are known as perv glasses. People are actively destroying flock cameras all over.

#60This is great. Hopefully this device becomes so ubiquitous that it deters anyone from putting up hidden cameras.
