Proof needs two eyes and one clock.

A single camera can show you a moment, but it can’t prove one. There’s nothing beside it to check the claim against. AnchorCam Stereo pairs two global-shutter sensors sharing one clock, so every capture carries geometric proof no single feed, real or AI-generated, can fake. That proof is signed in hardware the moment it’s captured.
