I'm going to sell glasses that have IR LEDS in them that are unreasonably bright. Any camera looking at you will either only the light of a thousand sun eminating from my face or compensate so drastically that it will only see the LEDs, and everything else will be blacker than night.
This is what I want and can't seem to find. I'm not good enough at soldering to do it myself and have been instead looking at buying an IR flood light for cameras to just clip on.
Would this work on license plate tracking cams like flock?
There's already a whole community for that sort of thing
Where might one find that community?
Just go to your local law enforcement and look for the "people who for some reason think making themselves extremely noticeable will stop us tracking them" folder. It's basically doing this.
"Hey, do you know where I could find more information on hammers?"
"Yeah, look for all the idiots with broken windows because they decided they didn't like using keys! Hahuhaha"
It's quite fun to assume everyone but you is an idiot, but I am in fact aware of that xkcd, and more importantly the myriad benefits of blending in. That doesn't mean that having another potential tool wouldn't be useful in specific situations.
I enjoy keeping up with red team style covert infiltration tools and hearing about what actually works in the field for the professionals that do this shit for a living. This video is mostly a guy having fun showing off how much of his own company's stuff he can fit in a suit, but it gets the point across and touches a little on sureptitious use when he talks about his RFID cloner.
My specific interest in a group investigating this sort of thing was in the actual testing and investigation. To see if anyone had managed to actually test the "overwhelm them with IR" urban legend against any modern equipment, because the last serious test of it that I'm aware of was a decade ago, and the resulting "hat" was obvious as fuck like the hypothetical in the XKCD.
I've done a quick search and found a slightly more recent experiment done in 2018 attempting to fool facial recognition instead of just blinding it. Vice overview here, arxiv paper here.
The hat is still pretty damn conspicuous if you ask me:
But it's also 8 years old.
I'm curious on if modern camera equipment like FLOCK has just spent the extra few cents per 100 units for an IR filter, and if the massive strides forward with LED tech might allow for something less horrendously obvious.
I suspect that the most easy and covert method (if you don't care about adding property damage and the like to your rap sheet if caught) is still just to use a stupid high powered laser to burn out the camera sensor from outside the angle it covers.

This will only work at night, on cameras that use IR sensor. Under normal daylight conditions it won't do anything.
Well that's disappointing. Guess I'll have to integrate visible wavelength LEDs too. I'll just market them as a wearable work light.
It's not about wavelength, but about intensity.
At night, in darker conditions, cameras dial up their light sensitivity so that they can see faint light (the human eye does the same thing through the iris). So in that mode, they're sensitive to the brightness that can be produced by human-made light emitters.
But during the day, they're already set for sunlight levels of brightness so that blinding them in that setting will require more light than is feasible to produce using normal light emitting technology. Infrared or visible light.
Think about trying to blind someone with your car headlights in the middle of a bright sunny day. It just doesn't work.
So i just have to get out at night? Mmh interessing
And not under particularly bright indoor lighting.
TBH the tiny Meta glasses cam probably won’t work at night anyway. If it’s small enough to be “stealth” then it just can’t pick up much light.
1,000,000 lumen work light glasses. What kind of work, you ask? The Lord's work.
Unless you use ir LEDs that could be mistaken for a weapon.
The daylight thing is accurate, but almost all cameras pick up IR.
You can point an IR TV remote at your phone's camera and see the lights blinking when you click buttons.
I don't think that works these days.
Works on both my phones. Samsung Fold 6 and Razr 2024+
It will still work in daylight, but the LEDs you'd use would have to be brighter than the sun.
Unless the camera has two separate sensors/lenses, one with an IR filter and one without.
While I like the intention, doesnt this risk burning the eyes of people arround you? Specially durint night? IR may be invisible but it's still light.
Might blind people if you could even manage to get them that bright without extra glowing or obvious power sources.
