Cashier Sentinel

Loss prevention at the counter: a virtual tripwire on the camera detects customer–cashier exchanges, groups them into sessions and reconciles them with the POS. Exchanges with no recorded sale go to human review.

RoleI designed the architecture, built the proof of concept and took it to production end to end, with the Emilia team.

  • change detection (SSIM)
  • session clustering
  • POS reconciliation
