How the estimate works

The math behind the number

A quick, honest model — not a guarantee. Your real numbers depend on layout, staffing, and how much guests have to divest.

Throughput per lane

Each walk-through detector clears roughly 400–900 guests an hour depending on how thoroughly you screen. Lighter divest = faster lines.

Your entry window

We divide your attendance by how fast you want everyone in. Doors open an hour early? That hour is your window. Tighter window = more lanes.

A backup unit

For larger checkpoints we suggest a spare on standby, so a single unit going down never stops the line. Peace of mind at the gate.

This planner gives a planning-level estimate based on industry throughput ranges (about one detector per 500–1,000 guests per hour). For a firm recommendation, we'll factor in your venue layout, arrival pattern, staffing, and local requirements.
