System Overview

How It Works

A compact hardware node sits between your device and your camera network — zero modifications to existing infrastructure.

01
🖨
Device Outputs Data
Your POS, cash counter, or slot machine sends transaction data over serial (RS232) or TCP/IP — exactly as it already does.
02
⚡
Node Filters & Processes
The CamOverlay node reads the data stream, applies your configured filters (show only TOTAL, CASHIER, VOID etc.) and queues it for display.
03
📷
Camera Shows Overlay
Lines scroll onto the camera's live view and recording via the camera's native OSD API. No additional hardware or software at the DVR/NVR.
