The final AntiCam pin, version 2: a dark grey case with a clear acrylic window over the emitter module and its three-by-three grid of emitters

Final prototype V2, the clip-on pin: the emitter module under a clear acrylic window.

  • 30+ prototypes and four major versions, from laser-cut discs to clear acrylic pins.
  • Tested against a live Ring doorbell camera at night: the sensor recorded a glowing orb where the face should be.
  • It works with light, not radio: unlike a jammer, which is illegal, it jams and damages nothing.

AntiCam is my wearable privacy device: an infrared LED array and a retro-reflective lining that keep cameras from capturing a usable image of me, without jamming or damaging anything.

Versions

  1. First

    Proof of physics: a single IR module on laser-cut discs with four coin cells. Cameras see it, eyes do not.

    The first prototype: a navy laser-cut disc with the white COB module seated in a cross-shaped cutout

  2. Second

    First enclosure: laser-cut MDF housing, logo engraved into the lid, carryable.

    Laser-cut MDF plates for the second prototype on the laser bed, Tully Tech engraved

  3. Third

    Clip-on device: acrylic plates, nine hand-soldered coin cells joined with copper tape, tested against real cameras.

    A clear acrylic plate carrying nine coin cells joined by solder links and wire

  4. Final V1

    7 June 2023

    The generation that passed the doorbell test: the finished pin, and the under-brim cap array beside it.

  5. Final V2

    Six clear acrylic plates, coin cells and a slide switch, in three colourways.

    Six clear laser-cut acrylic plates for the AntiCam V2 pin laid flat: the LED plate with its module, a plate with four coin cells and a slide switch, spacer plates and the engraved lid

  6. Cap V2

    The final version: the emitter array moves under the brim of a cap, aimed where cameras look, with retro-reflective lining behind it.

The V2 clear acrylic parts laid out at an angle: cells and switch plate, LED plate, cutout plates, engraved lid

The V2 stack

The V2 stack laid out in order: cells and switch, emitter plate, spacers, lid.

Three AntiCam V2 pins side by side: white, dark gray and navy, each with a clear top showing the emitter module

Final V2, three colourways

Final prototype V2: white, dark gray and navy colourways.

Cap V2, under the brim

Cap V2: emitters set under the brim, with the lining behind them.

How it works

A Ring doorbell camera at night, 30 October 2025. When the cap’s emitters switch on, the camera loses my face to a white glare; to anyone standing there, nothing changes.

Test 2, phone camera: the emitter reads magenta to a sensor and dark to the eye.
