  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.

        And not under particularly bright indoor lighting.

    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.
